The SICK WS9-2D630 Photoelectric Sensor is a compact industrial sensor from SICK’s WS9 family, designed for 10–30 V DC operation and a typical current draw of about 30 mA. It uses a visible red light source with PMMA optics inside an ABS housing and is rated IP69K for harsh washdown environments, offering a sensing range of 0–5 m (with a maximum range up to 7 m in certain configurations) and a fast response time of ≤ 2.5 ms. Connection options include a 4‑pin M12 connector or a 2 m cable, and the device provides a switching output with light/dark operation to suit PLC integration.
