Sick GRTE18-P1112 Cylindrical Photoelectric Sensor PNP

SKU CH-BKTH-0791S

A cylindrical photoelectric proximity sensor with an M18 thread, 5 mm to 100 mm sensing range, visible red PinPoint LED, PNP complementary output and 2 m PVC cable

  • Visible red PinPoint LED for precise detection
  • Sensing range up to 115 mm with 8 mm light spot
  • PNP complementary output switches at 500 Hz
  • IP67 metal housing withstands –25 °C to +55 °C
  • 2 m PVC cable with 10–30 V DC supply

Sick GRTE18-P1112 cylindrical photoelectric sensor

The Sick GRTE18-P1112 is a cylindrical photoelectric proximity sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply and provides a PNP complementary output suitable for automation systems. The sensor uses a visible red PinPoint LED with a 650 nm wavelength for precise alignment.

Sensing range 3 mm to 115 mm

The maximum sensing range spans 3 mm to 115 mm, while the specified sensing range covers 5 mm to 100 mm. A potentiometer allows manual adjustment of the switching threshold for application-specific tuning. The sensor delivers a switching frequency of 500 Hz and a response time under 1,000 µs for reliable detection. It is not suited for applications requiring longer-range detection beyond 115 mm or higher switching speeds.

IP67 nickel-plated brass housing with 2 m PVC cable

The housing combines nickel-plated brass and ABS with a PMMA optics cover, rated IP67 for dust and water protection. A 2 m, 4-wire PVC cable provides the connection, and two fastening nuts are supplied for M18 x 1 mounting. The sensor operates from –25 °C to +55 °C and meets EN 60947-5-2 EMC standards. Build quality supports demanding industrial environments but the fixed cable length may limit placement flexibility.

Questions about this item

Will the M18 cylindrical sensor fit alongside my existing M18 mounts on the conveyor line?

Yes, the housing uses an M18 × 1 thread, so it shares the same mounting pattern as other M18 sensors you already have installed.

How can I verify the PinPoint LED is aligned correctly after wiring the 4-wire cable?

Turn the potentiometer until the visible red spot (Ø 8 mm at 100 mm) falls on the target; the complementary PNP output will then toggle cleanly at up to 500 Hz.

Does the box include a mounting bracket or just the two fastening nuts listed?

Only two fastening nuts are supplied; a separate mounting bracket must be purchased if your application requires one.
