Features 1. NC Functionality: Experience security with our Normally Closed (NC) magnetic door sensor. This design ensures that when the switch is in close proximity to the magnets, the circuit is completed (light ON), providing immediate alert. Conversely, when the switch is detached from the magnets, the circuit breaks (light OFF), ensuring a secure environment 24/7. 2. Optimal Sensing Capability: Boasting an impressive transmitting distance of 10-20mm, our recessed magnetic door sensor ensures swift and precise detection. Engineered with state-of-the-art technology, it offers stable performance that markedly boosts security system efficiency. Suitable for any residential or commercial space. 3. High Electrical Standard: Designed to operate efficiently within a safe electrical threshold, this sensor accepts an AC220V power supply, with a maximum load current of 500mA and a power capacity of up to 10W. It ensures safety without compromising on performance, activating magnetism only when powered. 4. Versatile Application: Our -pack magnetic door sensor set is for enhancing any home security, access control, or anti-theft alarm systems. Compatible with both wooden and aluminum alloy doors and windows, this sensor is a must-have for robust and resilient home safety solutions. 5. and Strong ABS Housing: Enclosed in a superior quality ABS plastic case, the sensor is crafted to withstand high temperatures and physical stress without deforming. The build guarantees a long service life and versatile application across a variety of environmental conditions.
