Sick VTE18-3E8112 photoelectric proximity sensor NPN

Photoelectric Proximity Sensor NPN

The Sick VTE18-3E8112 is a cylindrical photoelectric proximity sensor with an NPN switching output designed for industrial automation tasks. It detects objects using an infrared LED beam across a sensing range of 10 mm to 700 mm, with a maximum reach of 800 mm. The sensor operates on a 10 V DC to 30 V DC supply and features a potentiometer for straightforward range adjustment. It suits engineers integrating presence detection into conveyors, packaging lines or robotic cells.

Brass Nickel-Plated Housing IP67

The metal housing combines brass nickel-plated components with plastic elements and a PMMA optics cover, rated IP67 for protection against dust ingress and temporary water immersion. A fixed 2 m PVC cable with a 3.1 mm diameter and 0.14 mm² conductor cross-section provides a permanent connection without separate plug assemblies. The straight cylindrical form factor measures 63.6 mm in length, allowing installation in tight machine frames where right-angled variants would not fit. Operating temperatures span –25 °C to +70 °C for both use and storage.

Light Switching Mode 2 ms Response

The sensor switches on light reception (light switching) with a response time of 2 ms, enabling reliable detection of fast-moving targets on high-speed lines. A narrow 2.8° angle of dispersion keeps the beam focused, reducing false triggers from nearby reflective surfaces. Power consumption is capped at 30 mA with a 10 % ripple tolerance on the supply rail. UL file NMFT2.E175606 confirms compliance for North American control-panel installations. Buyers who need a PNP output, a plug-in connector or a longer cable must select a different variant.
