Banner Engineering T18SP6RQ Opposed-Mode Photoelectric Sensor

The Banner Engineering T18SP6RQ Opposed-Mode Photoelectric Sensor delivers long-range, non-contact object detection for industrial automation, with a sensing range of 0–20 m and a rapid <3 ms response time. As an opposed-mode receiver, it detects objects that interrupt a transmitted infrared beam, making it well-suited for conveyors, packaging machinery, material handling equipment, assembly lines, and automated production systems that require reliable high-speed detection. It operates on 10–30 VDC and provides a complementary PNP (programmable) output, with a switching frequency up to 160 Hz to support fast process cycles. The sensor features an M18 threaded barrel in a thermoplastic housing, a polycarbonate lens, and an M12 × 1 4-pin connection for robust wiring. Its protection rating of IP67 and IP69K enables use in demanding environments, and it operates from -40°C to +70°C. For retrofit or replacement planning, common alternatives include Banner QS18VP6RQ8.
