SICK WT150-P430 Photoelectric Proximity Sensor

WT150-P430 is a compact miniature photoelectric proximity sensor from SICK (6011044) in the W150 family, designed for diffuse-reflection detection over a 10–250 mm sensing range and a 10–200 mm switching range. The rectangular ABS housing measures 10 mm x 28 mm x 17.5 mm and weighs about 7 g, with a PC optics window and an IP67 enclosure for harsh environments. It uses a visible red LED light source and terminates to a male M8, 4-pin connector. Switching mode is Light/Dark, selectable via an L/D control cable, with a 270° potentiometer to set the threshold. Electrical specs include up to 100 mA output current, a response time ≤ 0.5 ms, and a switching frequency up to 1,000 Hz. The sensing angle is approximately 6°, and the sensing principle is diffuse reflection from objects, with a reference note for DIN 5033 90% reflectivity. The device operates from –25 °C to +55 °C and is UL-listed (UL File Nos. NRNT2.E128350 and NRNT8.E1283501). The package includes BEF-W150-A mounting bracket to ease installation. This WT150-P430 configuration is identified by part number 6011044 and is part of SICK’s W150 series, offering a small footprint with fast response for industrial proximity sensing.
