SICK WTT280L-2P1531 Inductive Proximity Sensor

The SICK WTT280L-2P1531 PowerProx long-range photoelectric proximity sensor is a multitask, background-suppressed device that uses optical time-of-flight sensing to reliably detect targets at distances up to 4 meters. Operated from a 10–30 V DC supply and drawing about 100 mA, this module is designed for robust inline automation on conveyors, packaging lines, and robotic applications where precise, non-contact sensing is essential. The sensor provides a PNP switching output and belongs to SICK's PowerProx family, praised for compact form and versatile detection modes that perform consistently across varying target colors and surface finishes. Typical installations ship with a 2-meter, 5-pin cabling option, simplifying integration into standard control panels and harnesses. With its background-suppression capability, the WTT280L-2P1531 minimizes false readings from clutter and reflective backgrounds, while the time-of-flight architecture supports stable performance in dynamic environments—ideal for line-scan tasks, pick-and-place operations, and safety-related sequencing where reliable non-contact sensing matters most.
