To increase the reliability, the supply voltage for a reflected light barrier is increased and the operating point of the phototransistor of the reflected light barrier is stabilized by a suitable control circuit.
It operates optically based on the reflection light barrier principle.
Fork-type light barrier with connecting cable (10 meters or 18 meters)
This print monitor symbol (15) is scanned by means of a light barrier (26), which is used to place the documents (12) in a printing position, and checks the presence and condition of the print via a program-controlled assessment unit (AE).
The angular speed of the crank (1) is measured by a reed contact, a light barrier, an induction loop, or a mechanical tachometer.
A photoelectric barrier located in front of the slot (9) detects a sheet (2) that projects out of the slot (9).
This zone is scanned by a photoelectric barrier (1) in the sharp range and issues the stop command by means of an evaluation logic.
The sheet-film reloading device (6) is also provided with a bifurcate photoelectric barrier (34h) which surrounds isolated sheets of film and identifies double sheets.
