At the core of the Sick WL4S-3F2130 lies a photoelectric retro-reflective sensing principle with autocollimation, enabling accurate detection even with shiny or low-contrast objects. It supports a sensing range of 0 to 2.5 meters (maximum 4 meters with suitable reflectors), using a highly focused PinPoint LED that emits visible red light at a wavelength of 650 nm. This tight light beam ensures the sensor can detect small objects or labels with precision while minimizing misalignment errors.
Built for speed, the sensor offers a rapid response time of less than 0.5 milliseconds and a switching frequency of 1,000 Hz, making it ideal for fast-moving conveyor lines or high-speed packaging systems. Its output is configured as PNP with dark switching, and it operates on a 10 V DC to 30 V DC supply, consuming just 20 mA, which helps reduce energy usage in continuous operations.
Encased in a slim, rectangular housing made of durable ABS plastic, with a front screen built from impact-resistant PMMA, the sensor achieves IP66/IP67 protection. This means itβs resistant to dust, water splashes, and washdownsβperfect for harsh industrial settings. The compact dimensions (12.2 mm width, 41.8 mm height, 17.3 mm depth) and M8 3-pin connector allow flexible mounting even in tight control cabinets or complex machinery. Its wide temperature range from β40 Β°C to +60 Β°C makes it dependable for both indoor and outdoor installations in Indian industrial environments.
