Reed Switch, SPST-NO/NC, 0.05A 1W, IP67

The DFROBOT Reed Switch is a compact, highly reliable magnetic proximity sensor engineered for accurate position detection. It operates on a simple yet effective principle: the unit consists of an inducting end containing a reed switch and a separate trigger housing a magnet. When these two parts are brought within 1 cm of each other, the magnetic field closes the reed switch contacts, completing the circuit. This action can detect the position change of an object, enabling precise control for functions like travel limiting and safety protection.

Characterised by outstanding reliability and a long operational lifespan, this switch is designed for continuous use in demanding applications. Its low power consumption and wide operating voltage range (0–380V DC/AC) make it incredibly versatile for various electronic and control systems. The high switching frequency of 200Hz allows for rapid response in dynamic environments.
