Automation Direct C18BAP2E Photoelectric Sensor

< p>Automation Direct's C18B-AP-2E is an 18 mm diameter tubular photoelectric sensor that uses diffuse sensing with background suppression to reliably detect foreground targets against cluttered backgrounds. It operates on 10–36 VDC and provides a PNP, 3‑wire output for straightforward PLC interfacing. The sensor emits a visible red light and offers an adjustable sensing distance in the 10–120 mm range, making it suitable for part detection on conveyors, machine frames, and other compact spaces where precise edge or presence sensing is required. Its metal housing and compact form factor support industrial environments, while its right-angle optics enable easier mounting in tight installations. This C18B-AP-2E variant is part of AutomationDirect’s C18 series, which prioritizes a compact 18 mm footprint with consistent electrical characteristics across diffuse-with-background-suppression models.
