The SICK WL36-B730 is a photoelectric retro-reflective sensor with a sensing range of 0.1 m to 15 m (extendable to 22 m under ideal conditions), using visible red light. It operates on 10–30 V DC, draws 40 mA, and offers a PNP/NPN switching output configurable for light-on or dark-on mode. The housing is glass-fiber-reinforced plastic rated IP65, sized 36 × 85 × 72 mm, with a 7-pin Q7 DC connector.
The IP65 rating means the sensor body withstands washdown and dust ingress — suitable for packaging, conveyor, or material-handling lines where hose-down cleaning is routine. The 7-pin Q7 connector carries both PNP and NPN signals; verify the pinout against your PLC input card before wiring, especially if the existing panel uses a different connector family.
