The SEF2410-AVN by CDVI is a vandal-resistant infrared photocell that protects the active zone on automatic swing/sliding doors and gates. This robust, vandal-resistant 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 10m 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. Active infrared photocell Robust vandal-resistant casing Ideal for protecting active machinery zones such as automatic doors Trigger immediate stoppage of machinery when a person is detected Up to 10m range between beam transmitter and receiver
