The Banner Engineering Q85VR3LP-T9 (P/N 30872) is a polarized retroreflective photoelectric sensor with an SPDT electromecanical relay output and an integrated programmable timer. Operating on universal voltage from 12–240 V DC or 24–240 V AC, it detects targets over a range of 80 mm to 4.6 m using a visible red LED beam with polarization to minimize interference from reflective backgrounds. Encased in a thermoplastic housing with IP67 protection (NEMA 4X), the unit includes a wiring chamber and measures about 65 mm high by 25 mm wide by 85 mm long, weighing roughly 291 g.
