SICK WT4-2P330 Photoelectric Sensor

The SICK WT4-2P330 Photoelectric Sensor (Art. 1015143) is a compact, non-contact proximity switch that uses a visible red LED and background suppression to reliably detect objects within a 4–130 mm sensing range. It operates on 10–30 V DC and provides a PNP switching output through a 3‑pin M8 connector; setup is quick thanks to a single teach‑in button or via a connected cable. Designed for industrial automation, the WT4-2P330 offers a small footprint and dependable performance on conveyors, packaging equipment, and pick‑and‑place cells where robust sensing is required. Key specifications include sensing range 4–130 mm, background suppression, LED indicator, 10–30 V DC supply, PNP output, and M8 3‑pin connection. This model is part of SICK’s WT4 family of photoelectric proximity sensors and is suitable for projects needing reliable, non‑contact detection with straightforward installation.
