Cables – Almax

[ Overview ]

What Are Cables?

Custom cable interconnects built around the device.

Cables are electrical interconnects made from one or more insulated conductors. The conductors may be used individually, grouped into a jacketed cable, arranged as twisted pairs, shielded for signal protection, or built into a product-specific harness with branches and terminations.

Within ALMAX Keypads & Interfaces, Cables belong to the Interconnects group. Their role is to move electrical signals or power between parts of the product system. They are normally hidden inside an enclosure or routed between assemblies rather than serving as the user-facing control surface.

Customers commonly consider a cable when a thin exposed flex tail is not the best mechanical fit, when components are separated by a longer distance, when the route must pass through a housing, or when a removable and serviceable connection is preferred. ALMAX treats the cable as part of the complete interface architecture rather than as an isolated commodity item.

ALMAX develops product-specific cable assemblies that carry signals or power between a custom interface and the host electronics when the connection needs routing freedom, distance, strain relief, or serviceability.

This page focuses on Cables as flexible, insulated interconnect assemblies for carrying signals or power through a product; related products and technologies are mentioned only where they help explain construction choices, integration, alternatives, or system fit.

[ System Fit ]

Where Cables Fit in the Product System

A cable may begin at a keypad, membrane switch, sensor, display, flexible circuit, smart interface, or small PCB and end at the host controller, motherboard, power supply, another module, or an external connection point.

Typical integration points include

A cable transition from a membrane or flexible circuit
A connectorized lead between a control panel and a remotely mounted PCB
A harness connecting switches, indicators, sensors, or other interface elements

A routed power-and-signal link inside an enclosure
A service loop that allows an assembly to be installed, opened, or replaced
A shielded connection for signals that require additional noise control

The cable route must work with the enclosure, mounting features, bend space, connector access, assembly order, and service strategy. Grommets, clamps, channels, overmolds, heat-shrink, boots, or other strain-relief features may be coordinated where the cable enters an assembly or passes through a housing.

[ How It Works ]

How Cables Work

An electrical source, sensor, interface, or controller places a signal or power onto a conductive path. The cable’s insulated conductors carry that electrical connection between endpoints while the insulation keeps adjacent conductors separated and protects them from the surrounding structure.
Additional construction can support the application:

Twisting conductors can help control coupling in selected signal paths.

Foil, braid, or combined shielding may be used when electromagnetic interference is a concern.

An outer jacket can protect the conductor bundle from handling, abrasion, and the defined operating environment.

Terminals or connectors create the contact interface at one or both ends.

Strain relief reduces mechanical loading where the flexible cable meets a rigid termination.

The final result is a routed electrical path selected around the product’s voltage, current, signal, movement, installation, and environmental requirements.

[ Variations ]

Common Types and Variations

Discrete wire leads

Best for simple point-to-point connections, individual power lines, switches, or small signal counts.

Multi-conductor cables

Used when several circuits need to follow one controlled route through the product.

Twisted-pair cables

Used when the electrical design benefits from paired conductors and controlled routing.

Shielded cables

Selected when sensitive signals or the surrounding electromagnetic environment require additional protection.

Coaxial constructions

Considered for signal paths that require a dedicated center conductor and surrounding shield.

Custom wire harnesses

Used when a cable assembly must branch to multiple components or connector locations.

Jacketed high-flex constructions

Considered when the route will experience repeated motion or needs a more flexible outer system.

Hybrid cable-to-flex transitions

Used when a thin interface circuit must transition into a more robust routed cable.

[ Applications ]

Typical Applications

Industrial control panels with electronics mounted away from the operator interface
Medical and laboratory equipment with internal modules, sensors, or replaceable subassemblies
Transportation and vehicle controls that require routed connections through constrained structures
Outdoor or rugged equipment where cable entry, abrasion, moisture, and service access must be considered

Appliances and commercial equipment with separated controls, displays, and power electronics
Test, measurement, and instrumentation systems with multiple internal signal paths
Smart keypads and embedded HMI assemblies that connect to host electronics through a harness
Wearable, flexible, or sensor systems that require a transition from a thin circuit to a conventional wire system

Suitability depends on the complete design, including electrical load, movement, bend behavior, chemicals, temperature, sealing, installation method, and applicable qualification requirements.

[ Benefits ]

Customer Benefits

Benefits include:

Routing freedom

Cables can bridge separated components and follow enclosure paths that are impractical for a short, exposed flex tail.

Mechanical robustness

Insulation, jackets, connectors, and strain relief can protect conductors during assembly, handling, and use.

Serviceability

Connectorized cables can support modular installation, replacement, or maintenance when the product architecture requires it.

System simplification

A defined cable or harness can combine multiple signal and power paths into a controlled assembly.

Assembly efficiency

Keyed connectors, labels, color coding, and managed branch lengths can reduce ambiguity during production and service.

Custom integration

ALMAX can coordinate the cable with the interface circuit, connector location, housing, mounting approach, and final assembly process.

Scalable development

The interconnect can be considered during design, prototyping, validation, and production instead of being added after the interface geometry is fixed.

[ Materials & Construction ]

Materials, Construction,
and Technology Options

Conductors

Stranded copper, tinned copper, or another conductor system selected for electrical and mechanical needs

Primary insulation

Materials such as PVC, TPE, silicone, PTFE, polyurethane, or other application-appropriate compounds

Shielding

Foil, braid, drain wire, or a combined shield where required

Outer jacket

A protective layer selected around flexibility, abrasion, chemicals, cleaning, temperature, or outdoor exposure

Terminations

Crimp contacts, soldered ends, IDC connections, terminals, contact pins, or connector housings

Strain relief

Heat-shrink, boots, clamps, grommets, overmolding, or mechanically retained features

Identification

Color-coded wires, printed labels, serialized markings, or keyed connector positions

Material selection must be based on the actual operating environment and applicable customer or regulatory requirements. Specific ratings, chemistries, electrical limits, flex life, and qualification results should be confirmed for the chosen materials and components rather than assumed from a general cable category.

[ Design Considerations ]

Design and Integration Considerations

[ Performance ]

Performance and
Durability Factors

Long-term cable behavior depends on the complete construction and use conditions. Important factors include conductor stranding, gauge, insulation and jacket materials, bend radius, flex frequency, routing, strain relief, connector retention, contact quality, shielding, sealing, temperature, chemicals, abrasion, and installation workmanship.

Depending on the design, materials can be selected for improved flexibility, temperature resistance, chemical resistance, abrasion resistance, or outdoor exposure. Those characteristics must be verified against the exact material grade and finished assembly.

A cable intended for static internal routing should not automatically be treated as a dynamic-flex cable. Repeated motion concentrates stress near connectors, clamps, sharp bends, and jacket exits, so the motion profile and minimum bend space should be defined before construction is finalized.

Electrical performance can also be affected by conductor resistance, cable length, current, contact resistance, capacitance, crosstalk, grounding, and shielding. The appropriate checks depend on whether the cable carries simple switch signals, sensor data, communications, lighting power, or another electrical load.

[ When to Choose ]

When to Choose Cables

Choose Cables when…

The connection must travel farther than a practical board-level or exposed flex-tail link.
The route needs flexibility through an enclosure or around internal structures.
The assembly requires robust insulation, jacketing, or strain relief.
A connectorized, replaceable, or serviceable link is preferred.
Multiple wires or branches need to be organized into one harness.
Signal and power paths must connect separated modules.
The product requires a cable-to-flex, cable-to-PCB, or cable-to-interface transition.

Consider alternatives when…

A thin membrane or flex tail can plug directly into a PCB—review ZIF.
The main need is a mechanically attached terminal on a wire or flex—review Crimped.
The selection centers on the mating interface rather than the routed conductor assembly—review Connectors.
Two closely spaced PCBs need a dense, low-profile connection—review Slim Stacking.
A circuit or module edge should mount directly to another board—review Castellation.

Simple First-Time
Customer Summary

If you are new to Cables, think of them as protected, flexible electrical pathways that connect an ALMAX interface or electronic subassembly to the rest of the device. They are commonly used when the connection needs more distance, routing freedom, mechanical protection, or serviceability than a short board-level tail. The most important things to consider are the electrical requirements, route and movement, termination method, and operating environment.

FAQ’s

Your questions, answered.

What are cable interconnects used for?

They carry signals or power between separated parts of a device, such as a keypad and controller, sensor and PCB, display and electronics, or interface assembly and host system.

How does a cable assembly work?

One or more insulated conductors create electrical paths between endpoints. Jackets, shielding, connectors, and strain relief may be added to protect those paths and support the product’s routing, signal, environmental, and service requirements.

What is the difference between Cables and ZIF?

A cable uses insulated conductors and is useful for longer, routed, mechanically protected, or serviceable connections. ZIF is a compact pressure-contact method typically used to mate a thin flexible or membrane tail directly to a board connector.

What is the difference between Cables and Connectors?

The cable is the routed conductor assembly. The connector is the mating contact system at an endpoint. A custom cable assembly may include connectors, but the two are not the same product scope.

Can ALMAX customize a cable assembly?

Yes. ALMAX develops custom B2B assemblies around project requirements such as conductor count, length, branching, wire gauge, shielding, jacket, labels, connector type, pinout, strain relief, routing, and integration with the interface or enclosure.

What affects cable durability?

Key factors include conductor construction, bend radius, movement, strain relief, jacket and insulation materials, connector retention, abrasion, chemicals, temperature, moisture, vibration, and installation method.

Are cables suitable for harsh environments?

They can be designed for demanding environments, but suitability depends on the exact cable materials, connectors, sealing, routing, qualification plan, and exposure conditions. Environmental performance should be verified for the finished product configuration.

When should I choose a cable instead of a flex tail?

Choose a cable when you need greater routing distance, protected conductors, robust strain relief, repeated handling, a service loop, or a conventional harness architecture. A flex tail may be better when the priority is minimum thickness and a short direct connection to a PCB. Structural
