The WTB12-3P2441 Photoelectric Sensor from Sick uses background suppression to differentiate target objects from surrounding surfaces, providing a dependable sensing range of 35 mm to 100 mm and a maximum limit of 175 mm. It features a visible red LED light source operating at a wavelength of 660 nm, delivering a precise 2 mm light spot at 60 mm distance. This setup makes it ideal for detecting small or dark objects on varying backgrounds with consistent performance.
With an ultra-fast response time of β€ 330 Β΅s and a switching frequency of 1,500 Hz, this sensor is built for high-speed manufacturing and packaging lines. Its complementary PNP output supports both light and dark switching modes, with a maximum output current of β€ 100 mA, ensuring compatibility with a wide range of PLCs and automation systems. Operating efficiently within a 10 V DC to 30 V DC supply range and consuming only 45 mA, it offers stable signal output and low power consumption.
Housed in a rugged metal enclosure measuring 15.6 mm Γ 48.5 mm Γ 42 mm, the WTB12-3P2441 offers IP66, IP67, and IP69K protection, making it suitable for dusty, wet, or washdown environments. Its M12 4-pin male connector ensures easy and secure installation in tight spaces. Trusted in the electronics, automotive, and packaging sectors, this sensor is engineered to perform reliably even in fluctuating industrial conditions. .
