Banner Engineering S18SP6FF50 Photoelectric Sensor

Banner Engineering's S18SP6FF50 Photoelectric Sensor is an epoxy-encapsulated emitter in the S18 series, packaged in a compact 18 mm plastic housing for barrel-mount installations and fixed-field detection at a 50 mm cutoff. As part of the EZ-BEAM family, it uses infrared light (880 nm) with fixed-field optics to deliver reliable sensing without adjustments, and it operates from a 10–30 V DC supply with a complementary PNP output. A 2 m (6.5 ft) cable provides straightforward integration into standard industrial wiring. This model is designed for opposed-mode sensing and must be paired with a compatible receiver to form a complete sensing pair (for example S18SN6FF50); Banner notes that one emitter and one receiver are required for opposed-mode operation. The S18SP6FF50’s epoxy encapsulation and barrel-mount construction support durability in harsh environments, making it suitable for object detection, position sensing, and line monitoring on conveyors and packaging lines where a compact, fixed-field emitter is advantageous.
