Engineered for high-precision detection tasks, the Sick WTB12-3P2431 Photoelectric Sensor uses a background suppression principle to eliminate false triggers caused by nearby surfaces. It operates effectively within a sensing range of 20 mm to 350 mm, using a highly visible red LED light source with a wavelength of 640 nm. The focused light spot diameter of 6 mm at 200 mm ensures sharp detection, making it particularly useful for identifying small or irregular-shaped objects.
This Photoelectric Sensor features a fast response time of β€ 330 Β΅s and supports a high switching frequency of 1,500 Hz, enabling rapid response in conveyor systems and automated packaging lines. It comes with a complementary PNP digital output and supports both light and dark switching modes. The sensor is designed to operate within a voltage range of 10 V DC to 30 V DC while drawing just 45 mA, making it highly energy-efficient.
With a compact rectangular housing measuring 15.6 mm Γ 48.5 mm Γ 42 mm, this sensor fits easily into tight machine spaces. The metal body and PMMA plastic front screen provide both durability and optical clarity. The M12, 4-pin male connector simplifies electrical installation, and the robust construction meets IP66, IP67, and IP69K protection standards, making it suitable for wet or dusty industrial conditions. The WTB12-3P2431 is trusted across a wide range of applications including parts detection, presence sensing, and small object recognition in demanding industrial automation setups. .
