Cylindrical angled photoelectric sensor with 2 m PVC cable

Sick

Sick VTF18-3P5812 Photoelectric proximity sensor PNP

SKU CH-B25S-8ZYG3

Photoelectric proximity sensor detects objects up to 45 mm away using infrared LED, PNP dark-switching output, and a 2 m PVC cable

  • Photoelectric sensing up to 50 mm range
  • PNP dark-switching output for reliable detection
  • IP67 enclosure withstands harsh environments
  • 10–30 V DC supply fits industrial systems
  • 2 m PVC cable simplifies installation

Industrial proximity sensing

The Sick VTF18-3P5812 is a cylindrical photoelectric proximity sensor designed for automation tasks that require non-contact object detection. Its PNP dark-switching output and 10–30 V DC supply make it compatible with standard industrial control systems. The angled light emission and potentiometer adjustment allow precise alignment on conveyor lines or packaging equipment. An IP67 enclosure rating ensures reliable operation in dusty or wet environments.

Cable and adjustment

A fixed 2 m PVC cable with 0.14 mm² conductors eliminates the need for separate connectors and simplifies installation in tight cable trays. The built-in potentiometer lets technicians set the switching point without software or teach-in procedures, reducing commissioning time. Infrared LED illumination provides consistent detection across varying surface colours while remaining invisible to operators. The plastic housing and PMMA optics resist common industrial cleaning agents.

Range and limits

The sensor detects objects from 0 to 45 mm with a maximum sensing range of 50 mm, suitable for short-range presence verification on assembly fixtures. Response time of 2 ms supports moderate line speeds but may limit use on very high-speed sorting conveyors. Operating temperature span of –25 °C to +70 °C covers most indoor and sheltered outdoor applications. Buyers needing longer detection distances or faster switching should consider alternative sensing principles.

Questions about this item

How often should I replace the potentiometer or LED in the VTF18-3P5812 sensor?

The sensor has no user-replaceable parts; the LED and potentiometer are sealed inside the IP67 housing and are designed for the unit's full service life.

What limits the sensing range first when the VTF18-3P5812 runs continuously?

The maximum sensing range is 50 mm and the rated range is 45 mm; the 2 ms response time and 10–30 V DC supply define the operating window under sustained use.

How much heat or noise does the VTF18-3P5812 produce during all-day operation?

Power consumption is 30 mA at 10–30 V DC with no moving parts, so heat is minimal and the unit runs silently within the –25 °C to +70 °C temperature range.
