Sick VTE18-4N4312 photoelectric proximity sensor NPN

Sick VTE18-4N4312 photoelectric sensor

The Sick VTE18-4N4312 is a cylindrical photoelectric proximity sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply voltage and provides an NPN switching output with selectable light or dark switching via an L/D control cable. The housing combines nickel-plated brass and plastic with an IP67 enclosure rating for harsh environments. A 2 m PVC cable with 0.14 mm² conductors terminates the connection.

Suited for short-range infrared detection

This sensor suits automation engineers who need reliable object detection between 5 mm and 350 mm using an infrared LED with a 2.8° dispersion angle. The potentiometer allows straightforward sensitivity adjustment for varying target reflectivity. Buyers who require sensing distances beyond 350 mm or a different output type such as PNP should look at alternative models. The fixed 2 m cable length may also limit installations needing longer runs or pluggable connectors.

5 mm to 350 mm sensing range defines fit

The decisive specification is the sensing range of 5 mm to 350 mm, which determines whether the sensor reaches the intended target in your application. This range is paired with a 2 ms response time and infrared light source optimised for diffuse reflection. Verify that the maximum distance and beam angle match your mechanical layout before purchasing. The IP67 rating and –25 °C to +70 °C operating temperature support use in wet or thermally demanding conditions.
