Cutler-Hammer 1451B-6507 Polarized Reflex Self-Contained Sensor

Cutler-Hammer 1451B-6507 Polarized Reflex Self-Contained Sensor is a DC-powered photoelectric sensor with the emitter, receiver, and signal-processing electronics integrated in one compact housing. As a polarized reflex device, it detects targets by light reflected from the object and uses polarized optics to reduce false triggers from ambient light or glossy backgrounds. It runs on 30 V DC, eliminating the need for an external amplifier or separate receiver. This self-contained design simplifies installation and wiring, making it suitable for compact automation footprints. The 1451B-6507 variant is part of the Cutler-Hammer/Cutler-Hammer 1451B family and is intended for non-contact sensing of reflective surfaces in industrial environments. Typical applications include detecting reflective parts on conveyors, packaging lines, and other automated systems where a simple, robust reflective-surface sensing solution is desired. The polarized reflex configuration helps maintain stable operation when targets vary in brightness or environmental lighting, contributing to more reliable detection without mechanical interruptions.
