reed switch sensor (pack of 2)

The reed switch sensor is a magnetic-activated electrical switch designed to open or close a circuit in the presence of a magnetic field. Supplied as a pack of 2, these sensors offer a reliable and long-lasting solution for position detection, security, and automation applications. Featuring a sealed glass construction, they provide fast and dependable switching without any physical contact, which reduces wear and ensures a long operational life.

These sensors can operate in normally open or normally closed configurations depending on the model, and they consume very low power, making them ideal for low-voltage and low-current circuits. Their compact and lightweight design allows easy integration into a wide range of electronic systems, from microcontroller-based projects to industrial equipment. Common applications include door and window security sensors, position and limit detection, home automation systems, automotive sensing, and embedded or IoT projects. The pack of two makes them perfect for prototyping, replacements, or small-scale installations, offering versatility and convenience for both hobbyists and professionals.
