KHJ24A Mining intrinsically safe bidirectional emergency stop lock switchDetailed product description：

The KHJ24A intrinsically safe bidirectional emergency stop lock switch for mining is an intrinsically safe electrical equipment for mining. Suitable for environments with gas and coal dust explosion hazards underground in coal mines, as well as industries such as coal, metallurgy, chemical, building materials, grain, transportation, and harsh ground environments such as coal preparation plants, steel plants, thermal power plants, grain depots, ports, etc. It is used for emergency locking protection of conveyor lines. It is equipped with an encoded fault location recognition circuit inside, and the electronic control system can identify the fault location through it.

Function characteristics of KHJ24A intrinsically safe bidirectional emergency stop lock switch for mining
The locking switch is equipped with an encoded fault location recognition circuit and an action status indicator light inside.  
When the tape machine malfunctions and needs to be stopped urgently, simply pull the cable at either end of the switch, and the travel switch will activate. After receiving this signal, the electrical control device of the tape machine sends a command to cut off the power supply of the motor. After troubleshooting, pull out the reset button and reset the switch. Without manual reset, the pull rod cannot return to its original position, and the switch plays a locking role.
