The KEYENCE LR-ZB100N distance-based laser sensor is a compact stainless-steel photoelectric sensor engineered for reliable presence and position detection in demanding industrial automation environments. With a rugged SUS316L housing and rectangular form factor, it performs on packaging machinery, CNC cells, and food-and-beverage lines where washdown, vibration, and short cycle times are routine.

Using a Class 1 red laser at 660 nm with an NPN open-collector output, the LR-ZB100N delivers stable detection on metals, plastics, and dark targets within its defined sensing window. A bright 3-digit 7-segment display streamlines setup and monitoring, while selectable response times (1.5/10/50 ms), Light-ON/Dark-ON output logic, an external laser stop input, and comprehensive protection circuits enable fast integration on 10–30 VDC Class 2 or LPS supplies, even under challenging ambient light.

The integrated 2 m pre-wired cable and IP68/IP69K, NEMA 4X, 6P, 13 enclosure ratings simplify installation in washdown and harsh areas, helping reduce downtime and maintenance costs, and it is backed by a 1-year warranty for added assurance in continuous-duty applications.
