2 Sets Magnetic Reed Switch AC220V Brass NC Wired Door Window Sensor Switch for Alarm System MR‑199

Feature: 1. Heat Resistant: Made of premium brass material, reed switch is resistant to high temperatures and deformation, ensures durability for long term use. 2. Normally Closed: NC represents normally closed function, circuit conducts when magnets are drawn together (light on), circuit disconnects when magnets separate (light off). 3. Functional Range: With a functional distance of 10‑20mm, providing fast reflection and precise detection that ensures efficient and reliable functionality. 4. Working Conditions: When the magnetic gate is energized, the voltage is controlled at AC220V, and the load current cannot exceed 500mA, the maximum power is 10 W. 5. Wide Application: Suitable for all access control and anti theft alarm systems. Can be installed on wooden or aluminum alloy doors and window. Specification: Item Type: Magnetic Reed Switch Model: MR-199 Material: Brass Connection Method: Normally Closed (When the door magnet is drawn together, it is in a conductive state) Rated Voltage: AC220V Package List: 2 x Pair of Reed Switches
