The Microcell from BEA is a set of single infrared beams offering protection in the threshold of a sliding door or on the guide rails of a swinging/folding door. The Microcell's transmitter sends an infrared beam to a receiver that, if broken, will deactivate the door until the infrared connection is restored.
Due to their compact design, they can be used in single or double doors, as well as specific applications such as railways, security entrances, etc.
The 10MICROCELL1D features a set of 2 transmitters & receivers with a 15 foot cable.
