Schurter Capacitive Switch Momentary NO Illuminated RGB OptoMOS Relay Stainless Steel IP67 3-101-422

Schurter 3-101-422 capacitive switch offering momentary normally open (NO) function with RGB illumination and OptoMOS relay output in a robust stainless steel housing rated IP67. This switch features a capacitive touch sensor that eliminates mechanical wear and provides an attractive design with either scratch-resistant ceramics or stainless steel ring illumination surfaces.

The switch supports variable supply voltages from 5V DC up to 28V DC and delivers a constant LED intensity powered by a multicolor RGB LED, allowing flexible indication options for diverse application environments.

Designed for industrial use, it offers protection against unintended switching, vandal resistance, and floating switch connections to ensure reliability and durability. The stainless steel housing and actuator provide mechanical strength and high resistance against environmental factors. The rated operating temperature span from -40°C to +60°C enables use in harsh conditions.

The output uses an OptoMOS relay for galvanic isolation, suitable for sensitive electronic control circuits and automation systems requiring minimal electrical noise and increased signal integrity. It is RoHS, IEC/UL 60950, and REACH compliant.

Applications include industrial automation, machinery control panels, commercial equipment interfaces, and harsh environment installations requiring robust, illuminated user contact interfaces with long-term reliability and precise operation.

Features momentary switch operation with normally open function. RGB colour illumination provides multicolor indication. Constructed with durable stainless steel housing and actuator. Offers high ingress protection of IP67 for water and dust resistance.

Supports input voltage range from 5V DC to 28V DC. Output type is an OptoMOS relay for galvanic isolation. Operates reliably between -40°C to 60°C ambient temperature. Current rating is 100mA for load compatibility. Equipped with scratch-resistant ceramics or stainless steel touch surface.
