WTV4FE-8416A120A00 Photoelectric Proximity Sensor 50mm Push-Pull IP66 | SICK

The Original New SICK WTV4FE-8416A120A00 (1123755) is a miniature photoelectric proximity sensor from the W4 series, engineered for reliable detection of glossy, flat, uneven, perforated, and transparent objects in intelligent industrial automation. Its V-optics background suppression principle ensures precise, colour-independent detection at a sensing range of 2 mm to 50 mm, while the PinPoint LED light source (visible red, 635 nm) enables accurate alignment. The push-pull output (NPN/PNP) with dark-on/light-on operation provides flexible integration, and the 182 mm cable with a 4-pin M12 connector simplifies installation. Housed in a compact 16 × 40.1 × 12.1 mm plastic enclosure rated IP66, the sensor operates from 10 V to 30 V DC across a temperature range of –40°C to +60°C.
