Harsh Environment Interfaces

In today’s market there is an increase in demand requiring human-machine interface to be designed to withstand harsh environments.

We have experience in custom designing and manufacturing high reliability user interface products and control panels that can operate in the harshest environment. Examples include under water, extreme temperature ranges, dust/sand, shock, and even constant G force. One of our designs included the cockpit controls in a fighter jet where extreme temperatures swings and G forces are common.

See our blog post to learn more about improving membrane switches to withstand harsh environments.

At a Glance: Harsh Environment Interfaces

• Harsh environment user interfaces are engineered to operate reliably in demanding conditions including underwater applications, extreme temperatures, dust, sand, shock, vibration, and sustained G-force exposure.
• Custom designs can incorporate environmental sealing, ruggedized construction, and application-specific materials to protect electronics from water, solvents, contaminants, and mechanical stress.
• Proven across aerospace, military, marine, industrial, automotive, and commercial applications where performance and reliability are critical.

Under Water Applications - Exposed to Solvents - Medical Device Wipe Downs

Let us help you reduce manufacturing risks; we have worked on a wide variety of applications including marine environments and consumer electronics where the user interface is exposed to water or liquid solvents. In these situations, it is critical that the electronic components are completely sealed from any outside containments that could damage the built in electronics.

When developing a product that needs to be exposed to constant water such as a control panel on a boat or an underwater application, it is important to select the correct supplier that can manufacture to these strict requirements.

Applications Include:

• Marine/Boat Controls
• Cleaning Equipment
• Pool and Spa Controls
• Outdoor Remote Controls
• Waste Water
• Chemical Pumping Products

Shock, Vibration and G-Force

Human-machine interfaces can be built to withstand the exposure of extreme shock, vibration and G-force. Construction and heavy moving equipment controls, marine controls, and aerospace controls are great examples where constant shock and vibrations are considered normal everyday use.

If required, we have AS9100 and ISO 9000 certified plants that globally support various Tier 1, 2, and 3 providers with a wide variety of critical application solutions.

A few examples of current programs we support include production support for communication, helicopter parts, countermeasures, cockpit lighting, ruggedized vehicles, avionics systems, and power supplies.

Applications Include:

• Heavy Equipment Manufacturers
• Aerospace, Military and Defense Products
• Automotive Manufacturers
