Banner Engineering S18SP6FF50 Photoelectric Sensor Switch

The Banner Engineering S18SP6FF50 Photoelectric Sensor Switch is an epoxy-encapsulated, barrel-mount sensor from Banner’s EZ-BEAM S18 family with a fixed-field sensing zone of 50 mm. It operates on 10–30 V DC and provides a complementary PNP output, wired through a 2 m PVC cable (4 conductors, 0.5 mm²). The compact 18 mm-diameter housing is epoxy-encapsulated for reliable operation in industrial environments and is IP40-rated for basic protection. Identified by the part number S18SP6FF50 (often cataloged as 30325), this model is the 50 mm FF (fixed-field) variant of the S18 series and is designed for barrel-mount installation where space is limited. The sensor package is suited for use on small conveyors, assemblies, and machine panels where non-contact presence detection is required, and it can be paired with Banner emitters and the EZ-BEAM family for extended sensing solutions.
