Reed Switch Module

A reed switch is a type of line switch component that realizes control by magnetic signals. It induces by a magnet. The “switch” here means dry reed pipe, which is a kind of contact passive electronic switch component with the advantage of simple structure, small size, and easy to control. When a magnetic substance approaches, the switch senses the magnetic force and is electrified; thus, the module outputs a low level. When there is not a magnet approach, the module is de-energized and will output high. The induction distance between the reed switch and magnet should be less than 1.5cm; otherwise, the module won't be sufficiently sensitive to the magnet field and give no response.The module can be applicable to a variety of devices including SPC exchange, photocopier, washing machine, refrigerator, camera, door contact, electromagnetic relay, gasometer, etc.   Features A reed switch module to detect the magnetic field. Different from Hall sensors which are generally used to measure t
