SICK WTT4SLC-3B2262B01 PowerProx Laser Distance Sensor

The SICK WTT4SLC-3B2262B01 PowerProx laser distance sensor is a compact Time‑of‑Flight device that delivers precise distance measurements from 100 mm to 1,300 mm using a visible red laser (658 nm) and outputs the distance value via IO‑Link. It offers a 1 mm resolution, repeatability of roughly 4.5–11 mm, and an accuracy of ±35 mm, with a fast update rate of 0.8 ms. The laser is class 1 under IEC 60825‑1. The unit is powered from 10–30 V DC and typically draws around 50 mA; it supports a configurable discrete output (NPN/PNP, Push‑Pull) in addition to the IO‑Link interface for basic signaling. The sensing window produces a spot size of about Ø4.4 mm at the 1,300 mm range, and the housing is rectangular with an M3 threaded mounting hole for secure installation. The WTT4SLC-3B2262B01 is designed for multitask photoelectric sensing across applications such as quality control in automotive and parts supply, handling and assembly lines, door and gate safety, loop control, and winding/unwinding operations, where fast, repeatable distance measurements improve positioning and process control. As part of SICK’s PowerProx family, this miniature distance sensor combines precise measurement with IO‑Link connectivity and robust packaging to withstand industrial environments.
