The Sick WTB27-3S1511 Photoelectric Sensor is designed with a background suppression function, using a focused 880 nm infrared LED to detect target objects within a broad sensing range of 100 mm to 1,600 mm. Its rectangular ABS housing measures 24.6 mm Γ 80.6 mm Γ 54 mm and features a built-in potentiometer for easy manual adjustment. The Γ 25 mm light spot at 800 mm distance ensures sharp and stable detection, even in reflective or cluttered backgrounds.
Powering this sensor is remarkably flexibleβit operates across a wide supply voltage range of 20 V to 250 V AC/DC and consumes β€ 2.5 VA. The relay-based change-over output contacts support up to 4 A switching current at 250 V AC or 24 V DC, making the sensor compatible with standard control circuits in most industrial applications. With a fast β€ 10 ms response time and a 10 Hz switching frequency, it is suitable for medium-speed automation tasks where timing accuracy is critical.
Built to thrive in tough shop-floor conditions, the WTB27-3S1511 holds an IP66/IP67 enclosure rating, providing reliable protection against dust and water ingress. It comes with a factory-fitted 2-meter, 5-wire PVC cable for straightforward integration into control panels or PLC systems. Operating temperatures range from β40 Β°C to +60 Β°C, making it ideal for both chilled storage zones and high-temperature production lines. Trusted across sectors like automotive, FMCG, electronics, and packaging, this model delivers consistent performance and reduces downtime by filtering out false triggers due to background reflections.
