SRB-RING LOCK/25

How it works: It uses infrared optical induction technology. When it detects an object within its proximity range (typically between 1 to 15 cm), it activates the built-in relay switch. LED Status Indicators: The switch features dual-color backlight rings. It glows blue while on standby and changes to green (or vice-versa depending on the configuration) when a user's hand triggers the sensor. Wiring Configurations: It usually comes equipped with standard NO (Normally Open), NC (Normally Closed), and COM (Common) output contacts to integrate seamlessly with magnetic locks, drop bolts, and automatic door openers.
