The Sick WTB4S-3P3161 Photoelectric Sensor operates using a photoelectric retro-reflective principle with advanced background suppression, enabling accurate detection of objects within a sensing range of 10 mm to 180 mm. Its PinPoint LED emits a focused visible red light with a wavelength of 650 nm, forming a clear Γ 6.5 mm light spot at 150 mm. This precise light targeting helps eliminate false triggers and ensures consistent detection even in cluttered industrial areas. The sensor's 5-turn potentiometer allows for fine-tuning the detection threshold to suit specific machine or conveyor line setups.
Operating on a standard 10 V DC to 30 V DC supply with a low 20 mA current draw, the WTB4S-3P3161 is designed for efficient power use without sacrificing performance. With a fast response time of under 0.5 ms and a switching frequency of 1,000 Hz, it delivers dependable performance in high-speed automation tasks. Its PNP digital output and light switching mode make integration with industrial PLCs seamless. The sensorβs slim rectangular ABS housing measures just 12.2 mm Γ 41.8 mm Γ 17.3 mm and connects via a 3-pin M8 cable with connector, making installation both compact and secure.
Rated at IP66 and IP67, the WTB4S-3P3161 withstands harsh environments, including moisture, dust, and mechanical vibration, making it suitable for use in automotive, FMCG, and packaging industries. Its reliable operation across extreme temperatures from β40 Β°C to +60 Β°C further strengthens its credibility for long-term use. Trusted for its performance, build quality, and cost-efficiency, the Sick WTB4S-3P3161 Photoelectric Sensor is a go-to choice for maintenance engineers and OEM integrators.
