Sick

Sick VS/VE18-3P3640 through-beam photoelectric sensor

SKU CH-GG37-ZPHRS

A through-beam photoelectric sensor detecting objects up to 20 m away with infrared light and a PNP dark-switching output

  • Detects objects up to 20 m away
  • Infrared LED emitter with 2.8° beam spread
  • PNP dark-switching output rated 100 mA
  • M12 4-pin connector for quick wiring
  • IP67 housing survives –25 °C to +70 °C

Industrial detection sensor

The Sick VS/VE18-3P3640 is a through-beam photoelectric sensor built for industrial automation tasks. Its cylindrical M18 housing suits machine mounting where axial optical alignment is required. The sensor delivers a maximum sensing range of 20 metres with an infrared LED source. It targets engineers needing reliable object detection across conveyors or access points.

Verify voltage and connector compatibility

Confirm your control system supplies between 10 and 30 volts DC with ripple below ten percent. The unit draws up to 30 milliamps and switches a PNP dark-switching output rated at 100 milliamps. A male M12 four-pin connector is required for wiring. The test input disables the sender when pulled to zero volts.

Rugged plastic housing rated IP67

The PBT/PC housing weighs 200 grams and measures 78 millimetres in length. It meets enclosure rating IP67 for dust and temporary immersion protection. Protection class III insulation applies. Operating temperature spans from minus 25 to plus 70 degrees Celsius. The M12 connector ensures secure, vibration-resistant installation in harsh environments.

Questions about this item

Does the Sick VS/VE18-3P3640 sensor include the M12 connector and mounting hardware, or must they be purchased separately?

The sensor has a male M12 4-pin connector built in. The mating cable or connector is not included and must be sourced separately. Mounting nuts for the M18 x 1 thread are also sold separately.

Should I choose the maximum 20 m sensing range or the 14 m operating range for my application?

Use the 14 m sensing range for reliable detection. The 20 m figure is the absolute maximum under ideal conditions; the 14 m range accounts for normal contamination and alignment tolerances.

What does the 250 Hz switching frequency mean when the sensor is installed on a production line?

The sensor can change state up to 250 times per second, so it can detect objects passing at intervals as short as 4 ms. This suits high-speed counting or positioning tasks.
