Feature: 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. Specification: 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. Package List: 10 x Pairs of Switches Note: The door induction sensor only provide a switch signal, cannot directly supply power, and cannot be directly connected to the light fixture
