Banner Engineering T18SN6FF50 Photoelectric Sensor

Banner Engineering T18SN6FF50 is an 18 mm diameter DC photoelectric sensor from the T18 family configured for Fixed Field sensing with a 50 mm cutoff, designed to detect small parts at close range while resisting background interference. It operates on 10–30 V DC and provides an NPN switching output. The standard variant includes a 2 m (6.5 ft) potted cable for straightforward wiring in control circuits. The fixed-field design defines a precise sensing zone suitable for compact installations on conveyors, packaging, and assembly lines where reliable presence detection at a fixed distance is needed. For opposed-mode operation, this sensor must be paired with a matching emitter and receiver; Banner notes that one emitter and one receiver are required for opposed-mode sensing.
