Sick VTE18-4P4812 Photoelectric Proximity Sensor PNP

Sick VTE18-4P4812 Proximity Sensor

The Sick VTE18-4P4812 is a cylindrical photoelectric proximity sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply and provides a PNP switching output with selectable light or dark switching via an L/D control cable. The sensor suits automation engineers and maintenance technicians who need reliable object detection in a compact M18 housing.

Upgrade From Basic Limit Switches

This sensor replaces mechanical limit switches or older diffuse sensors that lack the 5 mm to 350 mm sensing range and 250 Hz switching frequency. The jump is worth it when non-contact detection reduces wear, when the IP67 enclosure rating is required for wash-down environments, or when the 2 ms response time improves cycle speeds on packaging or conveying lines.

Straightforward M18 Installation

The sensor mounts via its M18 x 1 thread and connects through a 2 m, 4-wire PVC cable with 0.14 mm² conductors. No potentiometer adjustment is needed, so setup consists of aligning the radial optical axis and selecting the switching mode via the L/D wire. Common issues include exceeding the 100 mA output current, routing the cable where it can be pinched, or supplying voltage outside the 10 V DC to 30 V DC range.
