Banner Engineering S18SP6FF50Q Photoelectric Sensor

The Banner Engineering S18SP6FF50Q Photoelectric Sensor is an epoxy-encapsulated, 18 mm EZ-BEAM barrel-mount sensor from the S18 series with a fixed-field background-suppression setup at a 50 mm sensing distance. It operates on 10–30 VDC and provides a PNP output with either dark-ON or light-ON switching, accessible via a Quick Disconnect (QD) connection for fast wiring and field replacement. The 50 mm fixed-field design helps discriminate targets from background within the sensing range, making it well suited to presence/absence detection on conveyors, part alignment on assembly lines, and other automation tasks where reliable sensing at a short distance is required. Built for rugged industrial environments, the epoxy-encapsulated housing protects the sensing electronics in a compact cylindrical package, while EZ-BEAM optics contribute to stable performance across typical industrial targets. This sensor integrates with Banner EZ-BEAM systems and is commonly used when a compact, robust, 50 mm-range sensor with a PNP output and QD wiring is needed for automation controls.
