Cylindrical metal photoelectric sensor with angled head and M12 connector

Sick

Sick VTF18-4N5340 Photoelectric proximity sensor NPN

SKU CH-SJQK-4ZQS3

Photoelectric proximity sensor detects objects up to 45 mm with adjustable infrared LED, NPN output, IP67 brass housing, and M12 connector for 10–30 V DC supply

  • Detects objects up to 45 mm with infrared LED
  • Adjustable sensitivity via built-in potentiometer for precise setup
  • Selectable light or dark switching via control cable
  • IP67-rated metal housing withstands dust and water immersion
  • Operates reliably from –25 °C to +70 °C

Industrial sensing fit

The Sick VTF18-4N5340 is a photoelectric proximity sensor with an NPN switching output for 10 V DC to 30 V DC systems. Its cylindrical angled housing measures 78 mm and suits machine builders who need reliable object detection at close range. The M12 4-pin male connector allows quick integration into existing control cabinets. It is not for applications that require analog distance data or PNP logic.

Thermal and electrical profile

The sensor draws 30 mA with a 10 % ripple tolerance across the full supply range. An IP67 brass nickel-plated metal and plastic enclosure protects the optics from dust and temporary immersion. Operating and storage temperatures span –25 °C to +70 °C without active cooling. Infrared LED emission and a 2 ms response time keep power dissipation low in continuous duty.

Adjustment and mounting aids

A built-in potentiometer lets technicians set the switching threshold between 0 mm and 45 mm, while the L/D control cable selects light or dark switching without rewiring. The PMMA plastic lens resists common industrial solvents. UL file NMFT2.E175606 confirms component recognition for North American panel builds. No separate mounting bracket or configuration software is included.

Questions about this item

How do I wire the M12 4-pin connector for the NPN switching output?

Connect pins 1 and 3 to the 10 V DC to 30 V DC supply, pin 4 to the load, and pin 2 to the L/D control cable for light/dark mode selection.

What maintenance does the PMMA optics and IP67 housing require?

Wipe the plastic optics clean when dirty; the nickel-plated brass housing and IP67 seal need no routine servicing.

At what temperature does the sensor hit its operating limit first?

The ambient operating range tops out at +70 °C; sustained heat beyond that will cause failure before any other spec is reached.
