Sick VTF18-3P5412 Photoelectric Proximity Sensor PNP

SICK VTF18-3P5412 proximity sensor

The SICK VTF18-3P5412 is a photoelectric proximity sensor with a PNP dark-switching output. It operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 30 mA. The unit is designed for industrial automation tasks requiring reliable object detection at close range. Its compact cylindrical housing suits installations where space is limited.

Brass nickel-plated housing with IP67 rating

The sensor features a metal housing made of brass nickel-plated material combined with plastic, rated IP67 for dust and water protection. A 2 m PVC cable with a 3.1 mm diameter and 0.14 mm² conductor cross-section provides the connection. The angled light emission and potentiometer adjustment allow straightforward alignment during setup. Operating temperatures span –25 °C to +70 °C.

Replaces basic inductive or mechanical switches

This sensor upgrades from simple mechanical limit switches or inductive sensors that lack optical detection capability. The infrared LED light source and 2 ms response time suit applications needing non-contact sensing up to 45 mm. The jump is worthwhile when the environment demands IP67 sealing and a robust metal housing that resists vibration and contamination.
