CSM Series: Illuminated Capacitive Touch LED Sensor Displays

Forward-thinking capacitive backlit displays combine touch, color, and icons to elevate HMI design and eliminate size constraints.

VCC’s Capacitive Touch Sensors Take Illuminating Buttons to the Next Level

These small SMT solutions provide the perfect alternative to traditional, contact-based mechanical switches that wear out quickly.

With a 21st century take on physical buttons, the CSM sensors combine user feedback and a switch into a single input for streamlined design and more effective operation.

Made for Maximum Design Flexibility

From icons to switches, the CSM Series was designed to remove the barriers holding you back from designing the best possible interface.

Simplify the HMI with a Microcontroller/PLC

Connect the CSM to a microcontroller to simultaneously turn on the LED and signal a programmed event trigger such as turning on a relay that controls a motor. The CSM output interacts with the PLC input to signal the action.

Extend Life with a Standard Momentary Switch

Combine the CSM with a buffer/driver to act as a relay and better handle the load during operation while avoiding having to use a mechanical switch. This component will help handle the load connected to the CSM while driving the LED inside CSM at the same time.

Improve Reliability with a Latching Switch

Pair the CSM with a buffer or flip-flop driver connected to its output to handle the relay for standard “on/off” latch operations without an actual mechanical switch that could wear down. The driver helps manage the load connected to the CSM and will drive the LEDs inside the sensor.

Optional Overlay Icons Increase Safety

Humans process images 60,000 times faster than text, and icons will improve user operation. Add standard on/off, arrow, or alarm icons, or customize any design. The overlay used is durable and chemical-resistant.

Multiple Configurations Enhance Design

Choose to position the cap touch sensors on the HMI, or place them behind a thin glass or acrylic sheet for a sleeker, more modern aesthetic. The CSM can also be reverse mounted for additional design opportunities.

Streamline with Bi-Color or RGB LEDs

When using a microcontroller or PLC, a custom bi-color LED or series of RGB colors can be programmed to change color and trigger desired events on the device.

csm searies benefits and features

Compact + Innovative + So Much More.

Tiny Footprint. No Constraints.
Measuring only 15mm x 15mm x 3.20 mm, the series can combine multiple operator cues into a single, yet seamless LED sensor.
Reliable LED Technology
Advanced LED technology provides uniform illumination, high optical clarity, and long operating life in a range of standard colors. Custom colors are also available.
No Mechanical Switch = Longer Life
Replacing the mechanical switch with a durable cap touch sensor eliminates wear and tear while providing the power relay functionality.
SMT for Simplified Production

OEMs can take advantage of production efficiencies when using the surface-mount installation thanks to pick-and-place automation.

Interactive Control + Color Identification
Cap touch technology and color LEDs work together to ensure more effective control over the device and its functions.
Work Well in Various Working Conditions
The CSM sensors can be activated with a dry or damp hand, or when using touchscreen-compatible gloves.
