  • Photoelectric proximity sensing up to 45 mm
  • Infrared LED light source for reliable detection
  • PNP dark-switching output with 2 ms response
  • IP67 enclosure rating withstands harsh environments
  • Operates from –25 °C to +70 °C on 10–30 V DC

Industrial photoelectric sensor

The SICK VTF18-3P5940 is a cylindrical photoelectric proximity sensor with a PNP switching output designed for industrial automation tasks. It operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 30 mA. The infrared LED light source detects objects at a sensing range of 0 mm to 45 mm with a maximum range reaching 50 mm.

M12 connector and IP67 housing

A 4-pin M12 male connector provides the electrical interface for integration into control cabinets or fieldbus modules. The plastic housing and PMMA optics carry an IP67 enclosure rating, allowing installation in environments exposed to dust and temporary water immersion. A built-in potentiometer enables sensing distance adjustment without additional tools.

Dark switching with 2 ms response

The sensor uses a dark-switching mode, activating the PNP output when the light beam is interrupted by a target. Response time is specified at 2 ms, supporting reliable detection on fast-moving conveyor lines. Ambient operating and storage temperatures span –25 °C to +70 °C, maintaining consistent switching behaviour across extended shifts in unheated or outdoor installations.
