Securitron DPS-M-WH Securitron DPS-M Door Position Switch for Metal Doors, Concealed, 0.4 Amp, White DPSM-WH

The DPS-M-WH Recessed Magnetic Door Position Switch is a reliable security contact designed to monitor the open or closed status of metal doors in commercial access control, intrusion detection, and electronic security systems. Featuring a normally closed (N.C.) SPST switching configuration, this concealed magnetic contact provides dependable door position monitoring for compatible security installations.

Specifically engineered for steel and other compatible metal doors, the DPS-M-WH incorporates an enlarged cylindrical permanent magnet to overcome the magnetic shielding effects associated with ferrous door construction. The magnetic switch and matching magnet are installed directly opposite each other within the door and frame, providing discreet operation without exposed surface-mounted components.

Designed for recessed mounting, both components require a 3/4-inch (19 mm) diameter installation hole and approximately 15/16-inch mounting depth. The device supports door and frame gaps of approximately 1/2 to 3/4 inch, depending on installation conditions.

The switch features a maximum switching current of 0.4 amps AC/DC and operates across a temperature range of -40°F to +150°F. Its wired contact output supports integration with compatible electronic access control systems, delayed-egress timers, and door-prop monitoring controllers.

Featuring a white housing, the DPS-M-WH provides a discreet installation option for commercial buildings, hospitals, schools, warehouses, industrial facilities, and other secured environments requiring dependable metal door monitoring.
