Fys35 mine explosion-proof remote control is a new generation of explosion-proof remote control developed on the basis of F21 classic remote control. It has passed the exibibt4 intrinsic safety certification of relevant national departments, and obtained the national coal underground use license. It can work safely in the bad chemical coal mines and other flammable and explosive dangerous occasions.

FYs and fyf335 mining remote controller (hereinafter referred to as industrial remote controller) are used in the environment of methane and coal dust explosion. They can send wireless carrier signal and operate the panel switch of remote controller to start the transmitting function. When they are not in operation, the remote controller is in standby mode. The shell of remote controller is made of Q235A. The mechanism is reasonable and the explosion releasing performance is durable.
