HMI Input Devices

A touch so distinct.

Introduction To HMI Input Devices

An input device provides the user interface for medical, industrial, aviation and commercial products.
These are durable, lightweight, and flexible panels with strong adhesives that support various applications and endure harsh environmental conditions.
We can manufacture any shape and form using polycarbonates or polyesters with strong adhesion. We can even create keyboards that can withstand harsh environments.
We offer membrane switch solutions, PCB switches, touch keypads, backlit keyboards, pro-steel/vandal resistant & elastomeric keyboards.
These solutions can be customized in countless different ways based on our customer’s industry & requirements.

These are wafer-thin assemblies with an array of open momentary contact switches printed using conductive substrates.
SMD LEDs can be embedded & sealed in the membrane, making it an economical & superior alternative to Conventional Switching.
These membrane switches can be standardized or customized to suit individual requirements.

These are similar to ﬂexible membranes, except the contact layers of these switches are etched on a PCB panel.
They can be designed to incorporate discrete passive components, mechanical switches, surface mount devices and provisions for active components.
PCB switches are supported with riveted mountings. The complete assembly is self-supporting.
This HMI input device can also be housed in enclosures or integrated with other accessories.

Capacitive keyboards work primarily by detecting the change in capacitance on a capacitive pad spread across the keyboard.
They can also be termed touchscreen-based HMI input devices.
Unlike traditional keyboards, electricity is always flowing through a capacitive keyboard.
Capacitive keyboards are faster than contact keyboards as they only require a gentle push to register a keystroke.
The capacitive touchscreens also provide a superior user experience with an elegant design.

Integrated keyboards are HMI input devices developed by integrating PCBs with other top interfacing layers.
Protolab is equipped with the technology and expertise to combine these various features into a single product that serves multiple functions.
Integrated keyboards are used extensively across a host of industries.
We can manufacture them with a wide range of customizations that serves our client’s requirements.

These uniformly backlit keyboards can be created in multiple colors & designs.
Illuminated keyboards can also be manufactured with light guide films with a plunger for key contact.
Illuminated keyboards give keys greater visibility under low lighting.
They can be designed in white, colored or RGB LEDs.
They look elegant and Protolab can manufacture them in different sizes, shapes, colors, button types, etc.
Illumination can also be added as a custom feature to other HMI input devices.

Membrane Switch solutions are standard switch layouts available with or without tactile feedback.
They work on the principle of scalable modular dimensions and can be used in conjunction with a custom overlay.
Our range of standard products is compatible with most enclosures available in the market.
We can also manufacture membrane switch solutions with all kinds of customizations required by our clients.

Prosteel or Vandal-resistant keyboards are air-tight & designed to withstand the harshest environment or vandalism.
They can be manufactured with stainless steel, alluzinc, aluminium & even plastics.
They can be produced in various key shapes and sizes.
Legends such as braille can be engraved or etched with embossing or debossing effects on these keyboards.

Silicone Rubber Keypads can replace costly mechanical switches at a lower cost and provide greater design versatility.
Input devices topped with elastomeric keypads can look & feel like traditional mechanical switches without their disadvantages.
Like membrane switches, rubber keypads can be made to resist moisture and other harsh environmental conditions.
Screen printing enhances rubber keypads by printing the graphics on the tactile part.
Overcoating is added to extend their life expectancy when keypad graphics are exposed to high abrasion usage.

Metal touch Keyboards are designed on the principles of capacitance using metallic surfaces like steel.
They can be designed with audible and haptic feedback and are waterproof.
Another highlight of the technology is it can operate with water.
The metal plates can be anodized or printed as per custom specifications.
This HMI input system can be operated even with gloves.

Programmable keyboards allow for more accurate output and thus are one of the most time-efficient HMI input devices.
You can create your actions with Advanced Scripting, Program keyboard shortcuts, text snippets or launch programs.
The connector comes with additional USB ports to link with more HMI input devices.
They are used as a part of the controller assembly in aviation, defense, heavy machinery manufacturing, robotics, etc.
