REED Switches - 27/10/2020

What is a REED Switch? The REED switch is the sensitive element of the magnetic sensor. It detects the presence of a magnetic field, usually a permanent magnet. It detects without contact the position of the magnet and transmits an electrical on/off or analog signal depending on the model. Basic Principles   A REED switch […]
