ROLAND 037U695690- LEUZE 10-002/1

photoelectric (optical) sensor made by Leuze, used in Roland printing machines, sensors from Leuze are typically used for object detection, registration marks, or label / sheet edge detection in press automation. Leuze’s “switching sensors” portfolio includes through-beam, retro-reflective, and diffuse sensors. In a printing press (like Roland), this sensor likely helps detect the presence or alignment of printed sheets, enables registration (mark detection), or monitors sheet transport to synchronize phases of the press.
