The WLG4S-3P2232 Photoelectric Sensor from Sick is a powerful retro-reflective sensing solution that incorporates autocollimation for accurate, alignment-tolerant detection. It supports a sensing range of 0 to 3 meters (up to 5 meters max) and utilizes a PinPoint LED with visible red light at 650 nm. The light spot size of Γ 45 mm at 1.5 meters ensures precise alignment, making setup easy even in dynamic environments. Its response time is under 0.5 milliseconds and it operates at a high switching frequency of 1,000 Hz, making it ideal for fast conveyor applications and automated quality control.
Powered by a 10β30 V DC supply and consuming only 20 mA, the sensor is engineered for long-term, energy-efficient deployment. The PNP output supports both light and dark switching, enabling flexible integration into a variety of PLC systems. Housed in a slim rectangular ABS plastic body with a PMMA front screen, and sealed to IP66 and IP67 standards, the sensor is protected against dust, moisture, and industrial washdowns. Its compact size (12.2 mm Γ 41.8 mm Γ 17.3 mm) and M8 4-pin male connector allow for fast, space-saving installation in panels, brackets, and sensor arrays.
The Sick WLG4S-3P2232 is widely used in automated packaging lines, transparent material detection, and assembly verification systems. It excels in detecting clear PET bottles, plastic films, and small components moving at high speed. Maintenance engineers value its single teach-in button for quick calibration, while automation specialists trust its repeatable performance for reducing machine downtime. For students and trainees in industrial automation, this model provides hands-on insight into real-world sensor behavior, logic switching, and optical detection principles. Trusted globally, the WLG4S-3P2232 offers an excellent balance of precision, durability, and Sickβs commitment to industrial innovation.
