Auxiliary interlock of optical coupler Hall contactor

The invention relates to an auxiliary interlock of an optocoupler Hall contactor. The auxiliary interlock of the optocoupler Hall contactor comprises a shell; the circuit board is used for bearing a state output circuit module, and the circuit board is detachably arranged in the shell; the motion push rod is installed on the circuit board in a sliding mode, the magnetic block is detachably installed on the motion push rod, and the Hall magnetic field induction module is installed on the circuit board and located at the side end of the motion push rod. The magnetic field intensity received by the Hall magnetic field induction module is changed; and the state output circuit module is used for sending the magnetic field information acquired by the Hall magnetic field induction module. The device is novel in design, achieves the real-time monitoring of the state of the contactor, is rapid in output state switching, replaces mechanical interlocking, reduces the fault rate, and is high in practicality. 本发明涉及一种光耦霍尔接
