Magnetic Switch Sensor

This magnetic switch (reed switch) has two iron-nickel magnetic reeds sealed in a plastic case, overlapped with a small gap. When a suitable external magnetic field is within 2cm, the reeds contact and conduct to sense object position changes. It’s compact, lightweight, ideal for miniaturized equipment. Its switching elements are hermetically sealed in inert gas for long service life. Widely used in door/window limiters, proximity switches, instruments, automation/security/transportation devices, smart homes, etc.
