Description: 1. A 12mm Reed Switch/Sensor is an electromechanical component consisting of two metal contacts enclosed in a glass tube filled with an inert gas, separated by a small gap that can be closed when a magnet is brought near. 2. Size and Shape: The 12mm size refers to the diameter of the sensor's housing, making it relatively larger than some other Reed Switches, providing easier installation and mounting for various applications. 3. Operating Principle: When a magnetic field is applied, the normally open contacts are attracted and close, creating an electrical circuit; when the magnet is removed, the contacts spring back to their original position, opening the circuit again. 4. Versatility: Reed Switches can be used in various applications, including industrial control systems, HVAC systems, motor control, and even as a component in household appliances like coffee machines or vending machines. 5. High Reliability: The contacts within the switch have no moving parts except when they
