Photoelectric Sensors

This category stocks 269 Allen-Bradley photoelectric sensors covering a range of sensing modes and form factors suited to discrete detection and color identification applications. The most prominent family is the Bulletin 42KA Ultra Mini photoelectric sensor, available in standard diffuse, sharp cut-off diffuse, and transmitted beam configurations with both front and side through-hole mounting options — making them a common choice where space is constrained on a machine frame or conveyor. The 46CLR True Color Sensor series is also represented, offering diffuse-mode color detection in a stainless steel housing. Buyers searching for Allen-Bradley 42KA catalog numbers, photoelectric proximity sensors, diffuse mode sensors, or transmitted beam through-beam sensors will find multiple SKU variants in stock across both families.
