SEFB2408, Fixed 8m infrared beam, battery powered

This battery-powered infrared photocell is ideal for protecting the active zone on automatic swing/sliding doors and gates. By triggering the moving unit to automatically stop if a person or obstacle is detected in the zone, injuries and accidental damage can be prevented. This model has a 8m range between the transmitter producing the infrared beam, and the receiver picking it up at the other end. If the beam is interrupted, the desired action (such as halting machinery) is triggered.
