Banner Engineering T18SP6RQ Photoelectric Switch Sensor

Banner Engineering's T18SP6RQ EZ-Beam through-beam photoelectric receiver is a rugged, self-contained barrel-mount sensor designed to pair with Banner EZ-Beam transmitters for beam-break detection across long distances. It operates from 10–30 V DC and provides a complementary PNP output with a maximum load current of 150 mA, while wiring is accomplished via a 4-pin M12 integral quick-disconnect connector. The unit carries IP67/IP69K protection for washdown and harsh industrial environments and covers a wide operating temperature range from -40 °C to 70 °C. The sensing beam is infrared and offers up to a 20 m range, making it well suited for applications such as end-of-conveyor sensing or other line-level position checks where distance matters. Catalog number 33422 corresponds to Banner’s T18SP6RQ; Banner lists this model as obsolete and notes that replacement options exist, such as the T18-2VPRL-Q8. Legacy systems can reference the T18SP6RQ when planning upgrades to current Banner sensors.
