The working principle and characteristics of thermal reed relay
Relay is an electronic control device. It has a control system (also known as an input loop) and a controlled system (also known as an output loop). It is usually used in automatic control circuits. It actually uses a smaller current to control a larger A kind of "automatic switching" of electric current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
Thermal Reed Relay is a new type of thermal switch that uses thermal magnetic material to detect and control temperature. It consists of a temperature-sensing magnetic ring, a constant magnetic ring, a reed switch, a thermally conductive mounting piece, a plastic substrate and some other accessories. The thermal reed relay does not use coil excitation, but the magnetic force generated by the constant magnetic ring drives the switch action. Whether the constant magnetic ring can provide magnetic force to the reed switch is determined by the temperature control characteristics of the temperature-sensing magnetic ring.
