Sick VTE18-3E2812 Photoelectric Proximity Sensor NPN

Sick VTE18-3E2812 Photoelectric Sensor

The Sick VTE18-3E2812 is a cylindrical photoelectric proximity sensor designed for industrial automation and detection tasks. It operates on a 10 V DC to 30 V DC supply and provides an NPN switching output suitable for PLC inputs and control circuits. The unit uses an infrared LED with a 2.8° dispersion angle for reliable object detection. It targets engineers and technicians who need a compact presence sensor for conveyor lines or machine guarding.

Cylindrical Angled Housing With Potentiometer

The sensor measures 60.6 mm in housing dimension and features an angled light emission design for flexible mounting in tight spaces. A built-in potentiometer allows manual adjustment of the sensing range between 3 mm and 170 mm, extending to 200 mm maximum. The 2 m PVC cable with 0.14 mm² conductors and 3.1 mm outer diameter simplifies wiring without separate connectors. Plastic housing and PMMA optics keep weight low while achieving IP67 enclosure rating for dust and water protection.

Low Power Consumption And Wide Temperature Range

Power consumption is rated at 30 mA with a response time of 2 ms, enabling fast switching in high-speed applications. The device operates reliably from –25 °C to +70 °C in both operating and storage conditions, covering cold storage and heated industrial environments. UL file NMFT2.E175606 confirms compliance for North American installations. The light-switching mode activates the output when the beam is received, providing predictable logic for safety and counting functions.
