GEJ30 (A) intrinsically safe wireless deviation sensor for mining

The single-stage two-way deviation switch has the characteristics of small size, light weight and high strength. The contact rod is covered with flame-retardant nylon rod, which can roll and retract flexibly, and has the characteristics of wear resistance and strong applicability. The contact rod action drives the opening and closing of the travel switch contacts, which can realize the transmission of wireless frequency switch signals and can be used for controlling mechanical actions or limit control. It is mainly used for electrical signal detection of auxiliary transportation equipment in coal mines.
