Commercial Hands-Free Wave-to-Open Sensor | Microwave Doppler Technology | Adjustable 4"–24" Detection Range | 12–24VAC/VDC | IP54 Rated

The BEA 10MS31 Series Magic Switch is a commercial-grade, touchless automatic door activation sensor designed to provide convenient, hygienic, and accessible operation of automatic pedestrian doors without requiring physical contact.

Featuring advanced microwave Doppler radar technology, the BEA MS31 detects movement from a hand, wheelchair, cart, or other moving object within its adjustable detection zone, allowing users to activate compatible automatic doors without touching a traditional push plate.

With an adjustable detection range of 4 to 24 inches, the MS31 can be configured for close-range wave-to-open activation or longer-range detection in applications requiring greater accessibility.

The sensor features an adjustable 0.5–30 second relay hold time, selectable timed or toggle operation, configurable LED indication, and silent activation for noise-sensitive environments.

Available in Black, Gray, or White, the BEA 10MS31 Series offers multiple mounting configurations, including single-gang, double-gang, narrow jamb, and 6-inch round faceplates.

The durable polycarbonate and polyethylene construction features an IP54-rated enclosure, making it suitable for properly protected commercial environments exposed to dust, incidental water splashes, and routine cleaning.

Whether installed in hospitals, commercial offices, retail storefronts, cleanrooms, or industrial facilities, the BEA 10MS31 Magic Switch provides a versatile solution for touchless automatic door activation.

How the BEA 10MS31 Works

Step 1 – Approach the Sensor

A pedestrian approaches the automatic door and moves a hand within the configured sensing zone.

Step 2 – Microwave Motion Detection

The BEA MS31 detects movement using its microwave Doppler radar sensor.

Step 3 – LED Indication

The configurable LED responds according to the selected DIP switch setting.

Step 4 – Electrical Activation

The sensor activates its voltage-free relay contact, sending a signal to the connected automatic door control system.

Step 5 – Door Operation

The compatible automatic door operator receives the activation request and opens the door according to its programmed sequence.

Step 6 – Output Reset or Toggle

The relay returns to its normal state after the selected 0.5–30 second interval, or changes state according to the selected toggle configuration.
