Functional principle detail
Absence of reference object or reference surface
Housing design (light emission)
Rectangular
Safety-related detection zone
150 mm … 2,000 mm, Target with 6% remission or higher. The laser beam hits the target surface at an angle of incidence of 90°, the light spot is covered fully by the target. Distance front of sensor to reference surface: 150 mm … 2,000 mm, distance reference surface to background, e.g., step/opening: > 85 mm 1)

1) Customer may vary incident angle and target remission but needs to ensure effective reserve is within corridor as stated (the lower incident angle, the farther the distance the lower the reserve).
2) Average service life: 100,000 h at TU = +25 °C.
