Banner Engineering S18AE3FF100Q1 Photoelectric Sensor

The Banner S18AE3FF100Q1 is an epoxy-encapsulated, barrel-mount photoelectric sensor from Banner’s S18 series that operates on AC voltage and uses fixed-field background suppression with a 100 mm sensing distance. The suffix Q1 denotes the 4-pin 1/2-20 UNF quick-disconnect connection for easy wiring in industrial layouts. Built to withstand harsh environments, the S18 family is IP69K-rated for reliable wash-down applications. On the front, two LEDs—green to indicate power and amber to indicate sensing—provide clear, immediate status when power is applied and when a target is detected. Typical uses include presence/absence detection on conveyors and packaging lines, where a compact cylindrical sensor with robust sealing helps maintain performance in demanding production environments.
