Safety when the door opens
Pull-in protection
Photoelectric sensors to EN 12978 that prevent people or objects from being drawn into the winding mechanism of roller shutters and sectional doors.
Application
Photoelectric sensors used for pull-in protection on door systems must comply with EN 12978. Protection is required on doors whose design poses a risk of being drawn in when opening – such as roller grilles – or with door heights below 2.5 m, where people can reach into the danger zone of the winding mechanism as the door opens or closes.
Reliable operation is tested with a test rod of max. Ø 50 mm.
