The mine air door opening and closing state sensor is a magnetically driven position switch sensor. This product can be installed on the air doors at all levels of underground tunnels in the environment of methane and coal dust explosion in coal mines. It is used to monitor the opening and closing state of the air door, provide air door status information for ventilation management, and can send voice information. It can also convert the detected signal into various standard signals and transmit it to the mine monitoring system, and finally realize the centralized, continuous and automatic collection, processing and monitoring of the air door status of the entire mine on the ground.

It is suitable for underground coal mines containing explosive mixtures but no corrosive gases that damage insulation. Explosion-proof type: mining intrinsically safe type, explosion-proof mark: Ex ia Ⅰ Ma.
