Sick VTF18-3N1840 Sensor

The Sick VTF18-3N1840 is a photoelectric proximity sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply and provides an NPN dark-switching output. The unit suits automation engineers who need reliable object detection at short range.

Cylindrical Angled Housing

The sensor features a cylindrical angled housing made of plastic with PMMA optics. It carries an IP67 enclosure rating for dust and water protection. Connection is via a male M12 4-pin connector. A potentiometer allows on-site adjustment of the sensing range.

Check Voltage And Connector

Verify that your control system supplies 10 V DC to 30 V DC and accepts an NPN dark-switching signal. Ensure an M12 4-pin cable or matching junction block is available. Confirm the 3 mm to 90 mm sensing window fits the application. The sensor operates from –25 °C to +70 °C.
