Product details

Sensor overview and key ratings

The WLG4S-3P2232V is a photoelectric retro-reflective sensor from the SICK W4S-3 series, delivering a 5 m sensing range with a PinPoint LED visible red light source. The PNP output switches at 100 mA load current with a 500 µs response time, making it suitable for high-speed object detection on conveyor lines or packaging machinery. Rated IP66, IP67, IP68, and IP69, the sensor body and optics withstand high-pressure washdown and temporary submersion — a fit for food-and-beverage processing or outdoor material handling where sanitation protocols demand aggressive cleaning. Operating voltage spans 10 V to 30 V, with a temperature range of -30 °C to 60 °C, covering freezer-zone logistics and heated factory environments without derating.

The 15.25 mm wide housing fits into tight panel layouts or machine frames where space is at a premium. The M8 4-pin connector simplifies field replacement — no hardwiring, just unplug and swap, reducing downtime on a down line. Switching type is selectable between Light-ON and Dark-ON via the wiring, giving the integrator flexibility to match the sensor logic to the existing control scheme without a separate configuration tool.

Frequently asked questions

What is the closest functional second-source to the WLG4S-3P2232V?

The WTB4SL-3P2261 is a peer in the same W4S family but is a proximity sensor with background suppression (300 mm max range), not retro-reflective. It also uses a red laser rather than a PinPoint LED, and its IP rating stops at IP67 — no IP68/IP69. The WLG4S-3P2232V is the retro-reflective choice for longer-range (5 m) washdown applications.

What are the key dimensions of the WLG4S-3P2232V?

Width is 15.25 mm, height is 44.9 mm, and length is 22.2 mm.

Will the WLG4S-3P2232V drop into a panel specified around the WTB4SL-3P2261?

No — the WTB4SL-3P2261 is 12.2 mm wide versus 15.25 mm for the WLG4S-3P2232V, and the mounting hole pattern or bracket may differ. The connector is M8 4-pin on both, so wiring is compatible, but physical fit requires checking the mounting footprint.
