The door opens when passers-by or people near the door block the beam.


The sensor is a transmission type photoelectric sensor that is embedded in the sash, such as in a mullion.
The sensor is installed near the door with its photoelectric beam passing along the door, and it keeps the door opened while passers-by or people near the door block the beam.


1) The sensor can be used even where the depth is limited.
2) The sensor can be installed by one action, pushing the body into its mounting recess.
3) Self-test feature offers greater certainty of detection for pedestrians's safety.
 ・The door system conducts a self-test in every operation to check whether sensor's safety functions are working correctly.
Self-test in each single opening/closing cycle secures safety always
