Banner Engineering S18SP6LPQ Photoelectric Sensor

The Banner Engineering S18SP6LPQ is an 18 mm polarized retroreflective photoelectric sensor in the S18 Series, built as an epoxy-encapsulated barrel-mount device for compact installations. It operates on 10–30 V DC and uses a 4-pin M12 quick-disconnect connector to deliver a PNP output, with LO/DO (Light-ON/Dark-ON) mode configurable to suit different sensing needs. This model offers a polarized retroreflective sensing configuration with a practical 2 m range, making it suitable for detecting reflective targets when paired with a compatible reflector. The rugged construction and epoxy encapsulation help withstand industrial environments, while Banner’s EZ-beam optics are designed to deliver reliable sensing with minimal adjustments. With an 18 mm barrel diameter and a quick-connect M12 interface, the S18SP6LPQ provides a compact, field-installable solution for applications requiring a small footprint and a polarized retroreflective approach to non-contact sensing.
