Force, Position, HMI, Gas Sensing, Smart Textile, and Printed Electronics Products

Interlink invented the Force Sensing Resistor and brought it to market in 1985. The architecture uses a printed interdigitated circuit and conductive layer that decreases resistance as applied force increases, enabling predictable, analog force interpretation in compact form factors.

The standard FSR portfolio includes high-performance options such as the UX 400 series (0.5 N to 150 N), the X 400 series (0.3 N to 50 N), and the original 400 series (0.2 N to 20 N). This range supports design-in across medical interfaces, industrial controls, robotics, and consumer electronics.

For rapid evaluation, Interlink also offers hardware development kits with sensor variations, overlays, and adhesive options so teams can validate force behavior before committing to production geometry and stack-up decisions.

The Force Sensing Linear Potentiometer (FSLP) detects position along a straight path, making it useful for volume sliders, linear movement controls, and home automation interactions where users expect smooth, tactile navigation.

The Ring Sensor uses related force sensing principles in a 360-degree format, giving teams a dial-like interface pattern that can be integrated into compact industrial and consumer products without adding complex mechanics.

For early-stage design and prototyping, Interlink offers HDK options with sensor and connector variations. If standard shapes are not a fit, the custom solutions team can modify dimensions, geometry, and stack-up details for application-specific position sensing requirements.

The standard lineup spans resistive touchpads like VersaPad, joystick modules such as MicroJoystick, and industrial pointing devices including DuraPoint. These modules can add touchpad and directional control behavior to a wide range of electronic products.

Interlink’s HMI products emphasize rugged design principles for real-world use. When properly integrated, they are engineered to tolerate spills, dirt, vibration, and temperature stress in markets like healthcare, industrial automation, and field equipment.

Unlike many capacitive-only interfaces, these force-based and resistive solutions can be used with gloves, which is often required in hospitals, factories, and maintenance environments. HDK options are available to accelerate evaluation during design and prototyping.

The portfolio spans electrochemical gas sensor elements, digital and analog modules, environmental instruments, ozone analyzers, portable detectors, fixed monitors, inline systems, and connected wearables for OEM and commercial deployments.

This range supports product selection across air-quality monitoring, industrial safety, facility sensing, consumer wearables, and application-specific gas detection programs without fragmenting the experience across separate brands.

On this page, gas-related products are grouped together so users can browse the broader Interlink gas portfolio in one place while still reaching the right technical path for product follow-up.

The smart textile portfolio is built around stretchable printed electronics that can be integrated into textile substrates without conventional rigid boards or wire harnesses. That opens up product paths for heated apparel, body-worn sensing, rehabilitation garments, and other e-textile programs.

Current families include ElastaTherm heating elements, ElastaTrode printed textile circuits, ElastaSens textile sensors, ElastaMoist moisture sensors, and FES electrodes for rehabilitation and stimulation workflows.

These keypad programs are suited to industrial, electronics, and OEM interface requirements where enclosure fit, circuitry integration, tactile feel, and environmental durability all matter. Early design collaboration is a core part of the product-development process.

The category supports a broad set of surface finishes, embossing options, switch constructions, and integrated electronic features including LEDs and shielding.

Interlink can support membrane switching, graphic layers, printed circuitry, LEDs, shielding, adhesives, and mechanical integration as one coordinated assembly. This is useful when the user interface needs to fit the enclosure, electronics, labeling, tactile behavior, and environmental requirements from the beginning of the design process.

These programs are typically specification-led and are best handled through a design review so the final construction can be matched to the device architecture, production volume, and field environment.

These overlay programs support self-adhesive front layers with clear or tinted windows, through-holes, embossing, insert pockets, and digitally enhanced graphics. They are frequently paired with membrane keypads, microswitches, or PCB-based switching architectures.

This category is especially relevant for OEMs that need both functional interface protection and polished front-panel branding in a single engineered part.

The category covers everything from simple decals to intricate multi-colour labels and product badges. CNC cutting enables complex geometries without expensive hard tooling, and coordinated production with keypads or overlays keeps finish and colour consistency tight.

Because label requirements are usually specification-led, these items are presented here as contact-led products rather than shoppable checkout items.

Interlink supports printed electronics through additive and subtractive process combinations, conductive and insulative inks, and cost-effective prototyping paths. These offerings fit OEM teams that need custom electronic functionality in compact or flexible packages.

Together with Interlink sensing and interface programs, this category helps position the site as a broader product and technology system rather than only a sensor catalog.

These products can include printed conductive layers, stretchable electrode geometries, textile-compatible structures, and application-specific stack-ups for diagnostic, rehabilitation, stimulation, or wearable monitoring workflows.

Because electrode designs are usually application-specific, this category is presented as a contact-led product path rather than a generic off-the-shelf checkout item.

Interlink can support printed heating elements for smart garments, automotive seating, medical warming products, PPE, and other applications where conventional wire heater mats create too much bulk or limit product design.

These programs often involve thermal performance, comfort, washability, safety behavior, and manufacturing constraints, so they are best evaluated as a custom printed-electronics or wearable-system program.
