Reed Relays| Operation and Types of Reed Relays

Reed Relays

Reed relays are a reliable, fast switching solution which offer many advantages over conventional electromechanical or clapper relays. These relays feature few moving parts and provide true isolation when switched. Their speed of operation lies in the low-millisecond range, making them suitable for control systems that activate solenoids, motor starters, and other electromechanical devices.  Where …
