Sick VTF18-3F1812 proximity sensor

The Sick VTF18-3F1812 is a cylindrical photoelectric proximity sensor with background blanking for reliable object detection. It operates on 10 V DC to 30 V DC and provides a PNP light-switching output. The M18 x 1 threaded housing suits industrial automation tasks where precise short-range sensing is required.

Sustained operation under load

The sensor draws 30 mA and delivers up to 100 mA switching current at 250 Hz with a 2 ms response time. Focused optics produce a 3 mm light spot at 50 mm distance across a 3 mm to 90 mm sensing range. Circuit protection A, B, C and D guard against wiring faults during continuous use. IP67 enclosure rating ensures consistent performance in dusty or wet environments.

Build quality and daily mounting

The plastic PBT/PC housing and PMMA optics withstand –25 °C to +70 °C ambient temperatures. A fixed 2 m PVC cable with 0.14 mm² conductors and 3.1 mm outer diameter simplifies permanent installation. Radial optical axis and M18 threading allow direct mounting without brackets. UL file NMFT2.E175606 confirms compliance for industrial control panels.

Questions about this item

Does the 250 Hz switching frequency cause noticeable heat during continuous operation?

The sensor draws only 30 mA at 10 V DC to 30 V DC, so heat buildup is minimal even when running all day.

What power supply and wiring must I already have for the PNP output?

You need a 10 V DC to 30 V DC source with ≤ 10 % ripple and a three-wire cable rated for 100 mA load.

Will the M18 × 1 thread and 60.6 mm length fit the bracket I use for older M18 sensors?

Yes, the cylindrical M18 × 1 housing and 60.6 mm length match standard M18 mounting patterns.
