YINGHUA R-TB01 Infrared Touch Exit Button

The YINGHUA R-TB01 is a no-touch infrared exit button designed for door access control systems. It suits installers and facility managers who need a hygienic, hands-free release for electric locks. The unit mounts on a standard panel and provides NO, NC and COM output contacts for flexible wiring. Its IP55 rating allows use in damp or outdoor locations.

Sustained operation at up to 3 A across 12 to 36 V

The switch is rated for a mechanical life of 500000 cycles, so it maintains reliable actuation through heavy daily traffic. Infrared sensing eliminates physical wear on the actuator, keeping contact resistance stable over time. The stainless steel 304 faceplate resists corrosion, and the IP55 seal prevents moisture ingress during prolonged exposure. LED indication remains visible without added power draw.

Replaces mechanical push-to-exit switches

The jump is worth it when hygiene or durability outweighs the cost of a basic mechanical button. It removes the need for users to touch a shared surface, reducing contamination risk in healthcare, food or public settings. The 500000-cycle rating far exceeds typical mechanical alternatives, cutting replacement frequency. It does not suit installations that require a physical key override or where a hard-wired push button is mandated by code.

Questions about this item

How much heat or power does the R-TB01 draw when it runs continuously on a 12 V supply?

The button is rated for DC 12-36 V at up to 3 A, so at 12 V the maximum continuous power is 36 W.

What wiring must already be in place for the NO, NC and COM terminals to function?

A DC power source between 12 V and 36 V and an electric lock or controller wired to the NO, NC and COM contacts are required.

Will the IP55-rated infrared sensor still trigger reliably if mounted beside an older mechanical push-button plate?

Yes, the diffused infrared detection works independently of adjacent mechanical switches and the IP55 rating protects it in the same environment.
