Eclipse Security, Access Control Infared Touchless Exit Door Button - ECL-ACC420IR

Sold by Spark Technologies Ltd.

Description

Another great looking and functional sensor from Eclipse. This touchless door sensor operates using reflected infrared light. It can activate a door or relay when you wave your hand in front of it.

The sensor works by detecting infrared light at a pulsed frequency that matches the frequency of the emitter LED, built into the front of the device. This eliminates false operations due to infrared coming from nearby infrared sources like surveillance cameras and radiant IR illuminators.
