Sick VTF18-3F5840 photoelectric proximity sensor

The Sick VTF18-3F5840 is a cylindrical photoelectric proximity sensor with a PNP switching output designed for industrial automation tasks. It detects objects using an infrared LED light source within a sensing range of up to 45 mm. The sensor operates on a 10 V DC to 30 V DC supply voltage and features an IP67 enclosure rating for harsh environments. A potentiometer allows adjustment of the switching point for specific application needs.

Suited for automated lines needing compact object

This sensor suits engineers integrating presence detection into machinery where space is limited and a 75 mm housing fits. The M12 4-pin male connector simplifies wiring in standard industrial control cabinets. Buyers needing longer sensing distances beyond 50 mm or analog output signals should look at different sensor types. Applications requiring detection through transparent materials may also need alternative sensing principles.

Straightforward M12 plug-in mounting

Installation involves securing the cylindrical housing and connecting the M12 4-pin connector to a compatible cable or distribution box. The potentiometer is adjusted manually to set the exact switching threshold for the target object. Common issues include misalignment of the angled light beam causing missed detections and contamination on the PMMA optics reducing the effective sensing range. Ensuring the supply voltage stays within the 10 V DC to 30 V DC range prevents output errors.
