Camden CM-221/46N Touchless Switch Narrow Jamb

Overview

The CM-221/46N is a touchless door activation switch designed for narrow jamb frame installations where physical contact must be eliminated. This ValueWave™ switch deploys in healthcare, hospitality, and commercial facilities where hands-free entry reduces germ transmission and accelerates traffic flow. The narrow jamb variant fits standard door frames with limited horizontal space — install it where a single-gang or double-gang box won't fit.

Compatibility

The CM-221/46N operates standalone or integrates with electromagnetic lock strikes rated for 30VDC operation. It pairs with standard access control systems that accept a Form C contact (1A @ 30VDC). The switch does not require networked readers or TCP/IP systems — it is a passive activation device that triggers a relay output to control door hardware. Verify your lock strike or door operator accepts 30VDC switched closure before ordering.

Installation Notes

Mount the CM-221/46N in a surface-mounted narrow jamb box (compatible with CM-23D enclosure). Sensor range is field-adjustable from 2 inches to 8 inches — set closer for high-traffic areas to minimize false triggers, wider for accessibility compliance. Time delay adjusts from 0.5 to 20 seconds; toggle operation mode available for alternative activation logic. Operating temperature range is −13°F to 122°F, supporting indoor or outdoor deployment. IP65 rating handles splashes and water spray but not full submersion — suitable for wet environments (restrooms, kitchens) but not pool decks or heavy washdown areas. Requires filtered, regulated 12–24 VDC power supply (not included); peak current draw is 45 mA. Do not apply AC voltage or unregulated DC above 24V — warranty is voided. Response time is 10 milliseconds, meeting ADA-grade activation requirements for automatic door operators.
