SICK WT27L-2S930A01 Inductive Proximity Sensor

SICK WT27L-2S930A01 is a compact laser-based photoelectric proximity sensor from SICK (part no. 1017933) designed for non-contact detection of metal parts on conveyors, machines, and assembly lines. It offers a sensing range of 100 to 800 mm, enabling reliable detection across short to mid-range distances without a reflector. The device uses a laser light source at 650 nm and is Laser Class 2 under EN 60825-1, with a light spot specified to be about 2 mm in diameter at a 400 mm distance for precise sensing of small components. Power consumption is listed at under 2 VA, supporting energy-efficient multi-sensor installations. Within SICK’s WT27L family, this model provides a compact form factor suitable for integration into standard industrial control circuits, delivering dependable optical proximity sensing in typical manufacturing environments. The 1017933 designation identifies this unit in SICK’s catalog of compact photoelectric sensors, and the WT27L line is recognized for accurate, repeatable detection of metal targets without direct contact. Ideal applications include part detection on production lines, presence checks for metal workpieces, and safety-related sensing tasks where reliable object presence within 0.1–0.8 m is required while occupying minimal mounting space.
