Bernstein Optronic OR20RH-MAR5-0400-ALE Optical Sensor

The Bernstein Optronic OR20RH-MAR5-0400-ALE is a background-suppression photoelectric sensor from Bernstein’s OR20 family, engineered for precise, non-contact object detection on industrial lines. In this RH variant, the device uses background suppression to detect targets within a 0.4-meter range (0400), while ignoring uniform backgrounds, a common requirement in packaging and conveyor applications. The OR20 family features a snap-lock cover and an M16x1.5 mounting thread, enabling quick, secure installation in tight spaces. This MAR5-0400-ALE (ALET) variant denotes Bernstein’s connector/configuration option for this model, designed to integrate with Bernstein controllers and compatible mounting and wiring accessories. Typical use includes presence/absence sensing, part counting, and automation tasks where reliable 0.4 m detection is required and background interference must be minimized. As part of Bernstein’s Optoelectronic Sensors lineup, the OR20RH-MAR5-0400-ALE is supported by Bernstein’s range of reflectors, brackets, and cable accessories that tailor mounting and wiring to specific machine layouts.
