Product information

SICK WTV4-3 is a high-quality photoelectric proximity sensor with background suppression, designed to reliably detect deep black objects. It features a powerful IR LED light source, which means no influence on vision systems and best detection of low remission objects. With a sensing distance of 2 to 50 mm and adjustable operating distance of 5 to 70 mm, it is suitable for a wide range of applications. The WTV4-3 has a PNP complementary output with a maximum output current of 100 mA and a response time of less than 0.5 ms.
