Description
Camden CM-333/41SW SureWave™ Touchless Wave-to-Open Switch
The Camden CM-333/41SW SureWave™ Touchless Switch is a battery-powered, hands-free door activation switch designed for automatic doors, access control systems, request-to-exit applications, and retrofit installations. Featuring active infrared sensing, a stainless steel double-gang faceplate, and a hardwired SPDT relay output, the CM-333/41SW provides a practical way to convert traditional push-to-open switches to modern touchless wave-to-open operation.
Hands-Free Door Activation
The Camden CM-333/41SW uses active infrared sensing technology to activate a door without requiring physical contact. Users simply wave a hand in front of the sensor to trigger the connected automatic door operator or access control device.
Its adjustable sensing range allows installers to fine-tune activation for the application, helping reduce accidental triggering while maintaining convenient hands-free operation.
Ideal for Retrofit Applications
The CM-333 is battery powered but uses a hardwired relay output, making it especially useful when replacing an existing mechanical push button where relay wiring is already present but electrical power is not available at the switch location.
This hybrid design can simplify touchless upgrades without requiring a completely new wireless door activation system.
