Camden CM-221/A42W Touchless Switch Double Gang
Overview
The CM-221/A42W is a double-gang touchless switch designed to eliminate manual contact points in high-traffic access control environments. Operating at 30VDC, it integrates with networked door control systems and electromagnetic lock strikes. The infrared sensor activates a Form C contact (1A @ 30VDC) to trigger door unlocking or other networked access functions. IP65 rating means water and dust ingress won't disable it—essential for building entrances, restrooms, and corridors where cleaning agents or moisture exposure is routine.
Compatibility
The CM-221/A42W pairs with any networked access control panel or door controller that accepts a dry contact closure and supplies 30VDC power. Compatible with electromagnetic lock strikes rated for 30VDC operation. Works alongside HID credential readers and other networked access infrastructure in enterprise installations. No special integration module required—standard dry contact wiring connects to existing door control logic.
Installation Notes
Requires a filtered, regulated 30VDC ±10% power supply—do not apply AC or unfiltered DC above the specified range (voids warranty). Sensor range is field-adjustable from 2 to 8 inches (5–20 cm), allowing tuning for hallway traffic patterns or confined spaces. Activation time delay is adjustable from 0.5 to 20 seconds, and toggle operation mode is selectable for repeated activation without hand removal. Heavy-gauge stainless steel faceplate resists corrosion and cleaner damage. Double-gang configuration fits standard electrical boxes for surface or flush mounting. Peak current draw is 45 mA, ensuring minimal strain on low-voltage infrastructure.
