1、Premium Material: The switch housing is made of ABS flame retardant material, not easy to crack and aging, ensuring high temperature resistance and deformation resistance. 2、Wide Application: Designed for all access control and alarm systems, widely used for secure window, doors, and cabinets. The package includes 10 reed switches for your convenience. 3、High Performance: The sensor has a touch spot capacity of 0.5A (maximum switching current), a voltage of DC 100V, a rated power of 10W, and an operating distance of 15‑20mm. 4、Normally Closed (NC) Design: The NC design ensures that the circuit is on (the light is on) when the contacts are together. When separated, the circuit is off (the light is off). 5、Embedded Installation: This magnetic sensor can be installed on wooden or aluminum alloy doors and window, providing a versatile solution for your safety needs. Item Type: Recessed Wired Window Door Sensor Product Model: MR-34B Product Features: Flame Retardant ABS shell Connection Type: Normally Closed (When the door magnetic contacts are closed, it is in the conductive state) Voltage: DC100V Rated Power: 10W 10 x Pairs of Switches
