Available. The SICK WTB8L-P2131 is a miniature photoelectric sensor from the W8 Laser series, designed for precise detection of small and fast-moving objects in industrial automation applications. Operating on the principle of background suppression, it ensures reliable object detection by distinguishing targets from their surroundings. This sensor features a visible red laser light source with a wavelength of 650 nm, providing a light spot size of approximately 1.5 mm at a distance of 300 mm. The adjustable potentiometer allows for fine-tuning over four turns, accommodating various detection requirements. With a sensing range between 30 mm and 300 mm, it is suitable for applications such as feed monitoring on high-speed conveyors, pick-and-place verification of miniature components, and presence sensing in automated assembly lines. The sensor operates within a supply voltage range of 10 V DC to 30 V DC and has a current consumption of 30 mA without load. It offers a PNP switching output with a response time of ≤ 0.25 ms and a switching frequency of 2,000 Hz, ensuring rapid and accurate detection. The housing is constructed from ABS plastic, and the optics are made of PMMA, both materials contributing to its lightweight design of 10 grams. With an IP67 enclosure rating, the sensor is protected against dust and water ingress, making it suitable for harsh industrial environments. The ambient operating temperature ranges from –10 °C to +50 °C, and the storage temperature from –40 °C to +70 °C, ensuring reliable performance across a wide range of conditions. The sensor is supplied with a stainless steel mounting bracket (1.4301/304) for easy installation. For detailed specifications and further information, refer to the official datasheet.
