Infrared Touch Exit Button

The YINGHUA K9Button is an infrared touch exit button designed for door access control systems. It suits installers and facility managers who need a contactless release switch for secure entry points. The unit operates on DC 12-36V with a 3A current rating and provides NO, NC and COM output contacts.

IP55 Protection Limits

The switch carries an IP55 ingress protection rating, meaning it resists dust ingress and low-pressure water jets from any direction. It is not rated for immersion or high-pressure wash-down, so outdoor mounting should avoid direct exposure to heavy spray or standing water. The sensing range is fixed by the diffused infrared detection method.

Replaces Mechanical Push Buttons

This device replaces traditional mechanical push-button releases where touch-free operation reduces wear and improves hygiene. The mechanical life is tested to 500000 cycles, so the upgrade is worthwhile when existing buttons fail early or when a contactless interface is required for health-sensitive areas.

Questions about this item

Should I choose the version with or without the LED indicator for my access control system?

The K9Button includes a built-in LED light as standard, providing visual status indication for the exit button without needing to select a separate version.

What does the 500000 mechanical life rating mean for daily use on a busy office door?

The switch is tested to 500000 press cycles, which supports years of reliable operation even with frequent daily use in commercial environments.

How does the IP-55 rating affect installation on an exterior door exposed to rain?

IP-55 ingress protection allows the button to withstand water jets and dust, making it suitable for outdoor mounting on gates or exterior door frames.
