SEF2420 SEF2420 Adjustable infrared photocell, 20m range This 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 20m 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. The SEF2420 also benefits from adjustable optics. Key features: Active infrared photocell Ideal for protecting active machinery zones such as automatic doors Trigger immediate stoppage of machinery when a person is detected Up to 20m range between beam transmitter and receiver Adjustable optics TECHNICAL SPECIFICATIONS: Card / reader technology Infrared Number of Relays 2 Mounting Surface Min Temperature (°C) -10 Max Temperature (°C) 55 Range in Open Field (m) 20m between transmitter and receiver ELECTRICAL SPECIFICATIONS: Min.
