BEA MSO8U Magic Switch Touchless Microwave Switch

The BEA MS08U Magic Switch is a microwave, touchless actuator for automatic doors that detects motion with Doppler radar and converts it into a controlled relay signal to operate door hardware. It ships as a single-gang cream-faceplate assembly (faceplate variant 70.5276) and uses a four-conductor cable for power, signaling, and output, making it a compact, hard-wired activation device for standard door installations. The unit supports a 4–24 inch adjustable sensing zone and uses a 24.125 GHz microwave carrier, with an output mode that can be configured as Toggle or Pulse depending on the installation; the relay output is a switch-over contact (voltage-free) rated up to 60 VDC / 125 VAC and 1 A resistive. This MS08U model belongs to BEA’s Magic Switch microwave family, engineered specifically for automatic-door control with a straightforward mounting footprint suitable for single-gang installations.
