MKA-14 Magnetic Reed Switch (12mm, 2 Pin, Normally Open)

The MKA-14 Magnetic Reed Switch is a compact 12mm magnetic sensor designed for proximity detection, position sensing and magnetic switching applications. It features two ferromagnetic contacts enclosed inside a hermetically sealed glass tube. The normally open contacts close when a suitable magnetic field is applied and reopen when the magnetic field is removed. Its passive operation, compact construction and low power requirements make it suitable for security systems, automation equipment, electronic counters and embedded electronics projects.
