Sick VTF18-3N1312 photoelectric sensor

The Sick VTF18-3N1312 is a cylindrical photoelectric proximity sensor with an angled light emission design. It operates on a 10 V DC to 30 V DC supply and provides an NPN dark-switching output. The housing combines nickel-plated brass with plastic and carries an IP67 enclosure rating. This sensor suits automation engineers who need reliable object detection in confined industrial spaces.

Replaces older diffuse sensors with shorter range

The unit extends the sensing range up to 100 mm maximum and 90 mm nominal using infrared LED illumination. A built-in potentiometer allows quick sensitivity adjustment without external tools. The 2 ms response time supports fast cycling on packaging or assembly lines. The upgrade is worthwhile when existing sensors cannot reach the required distance or lack the rugged IP67 housing for wash-down environments.

Check voltage, output logic

Verify that the control system supplies 10 V DC to 30 V DC and accepts an NPN dark-switching signal. The fixed 2 m PVC cable with 0.14 mm² conductors and 3.1 mm outer diameter must reach the termination point without splicing. Confirm the 60.6 mm housing diameter and angled optics clear surrounding machine structures. The operating temperature span of –25 °C to +70 °C must cover the intended ambient conditions.

Questions about this item

What are the housing dimensions and thread size for mounting the VTF18-3N1312?

The cylindrical angled housing measures 60.6 mm overall with an M18 thread for panel or bracket mounting.

How do I wire the NPN dark-switching output and set the sensing distance?

Connect brown to 10–30 V DC, blue to 0 V, and black to the load; then turn the potentiometer to adjust the 3–90 mm range.

When should I replace the cable or clean the optics on this IP67 sensor?

Inspect the 2 m PVC cable for cracks after repeated flexing and wipe the PMMA lens if contamination reduces the 100 mm maximum range.
