S18 Series Photoelectric Sensors

Banner Engineering S18 Series Photoelectric Sensors feature EZ-beam technology with specially designed optics and electronics for reliable sensing without adjustments. The sensors are self-contained, fixed-field, infrared diffuse mode sensors with far-limit cutoff, which is a type of background suppression. High excess gain and fixed-field technology allow the components to detect low-reflectivity objects while ignoring background surfaces. The S18 EZ-beam series sensors feature a -40°C to 70°C operating temperature range, <1 microamp at 30VDC off-stage leakage current and a 20mA receiver current. These Epoxy encapsulated barrel-mount sensors are leakproof, rated NEMA 6P and IEC IP67 per IEC 60529.
