Sick VTF18-3P5640 Photoelectric Proximity Sensor PNP
A cylindrical photoelectric proximity sensor with focused optics and background blanking, sensing up to 45 mm with a PNP dark-switching output in an IP67-rated M18 housing
- Background blanking ignores objects beyond 45 mm
- Focused infrared LED produces a 3 mm spot at 25 mm
- PNP dark-switching output handles 100 mA at 250 Hz
- IP67-rated PBT/PC housing survives –25 °C to +70 °C
- M12 4-pin connector simplifies installation on 10–30 V DC systems
Sensing range and detection
The VTF18-3P5640 is a cylindrical photoelectric proximity sensor that uses background blanking to detect objects up to 45 millimetres away. It operates on 10 to 30 volts DC and provides a PNP dark-switching output with a maximum load of 100 milliamps. The M12 four-pin connector suits standard industrial wiring.
Sustained operation and protection
The sensor draws 30 milliamps and maintains a 250 hertz switching frequency with a two-millisecond response time. An IP67 enclosure rating and circuit protection classes A through D protect the electronics during continuous use. The plastic PBT/PC housing and PMMA optics withstand ambient temperatures from minus 25 to plus 70 degrees Celsius.
M18 threaded mounting constraint
The M18 by 1 thread and 78-millimetre housing length fix the mechanical envelope, so the sensor only fits openings cut to that specification. Builders needing a different thread size, a longer body or a side-looking optical axis must choose another model.

Questions about this item
How much power does the SICK VTF18-3P5640 draw when running continuously on a 24 V DC supply?
The sensor consumes 30 mA from a 10 V DC to 30 V DC supply, with a maximum ripple of 10 %.
Which connector and voltage must my control cabinet already provide for this PNP sensor?
A male M12 4‑pin connector supplying 10 V DC to 30 V DC is required for the PNP dark‑switching output.
Will the M18 × 1 threaded body and 78 mm length fit the mounting brackets I use for older M18 sensors?
Yes, the cylindrical housing uses an M18 × 1 thread and is 78 mm long, matching the standard M18 form factor.
