Cylindrical M18 plastic sensor body with 2 m PVC cable, 63.6 mm long, IP67 rated

Sick

Sick VS/VE18-3P3612 Through-beam photoelectric sensor PNP

SKU CH-Y073-BYKDB

Through-beam photoelectric sensor with 14 m sensing range, PNP dark-switching output, 10–30 V DC supply and IP67-rated cylindrical M18 housing

  • 20 m max sensing range for long-distance detection
  • 14 m operating range with 700 mm spot size
  • PNP dark-switching output handles 100 mA loads
  • IP67-rated plastic housing withstands –25 °C to +70 °C
  • 2 m PVC cable with 3-wire connection simplifies wiring

Sensing range and output

This through-beam photoelectric sensor detects objects at distances up to 20 metres with a practical range of 14 metres. It supplies a PNP dark-switching output rated at 100 milliamps and operates on a 10 to 30 volt DC supply.

Cable and housing features

A two-metre three-wire PVC cable with a 3.1 millimetre diameter connects the sensor without separate plugs. The cylindrical M18 by 1 threaded housing is 63.6 millimetres long and made from PBT/PC plastic rated IP67 for dust and water ingress.

Installation notes

Axial optical alignment and a 2.8 degree dispersion angle mean the emitter and receiver must face each other precisely across the gap. The sensor has no sensitivity adjustment so mounting position determines reliable detection. Wiring must observe the 30 milliamp power draw and the 2 millisecond response time for correct PLC timing.

Questions about this item

Will the 2 m PVC cable need replacement in harsh environments?

The 2 m PVC cable with 0.14 mm² conductors and 3.1 mm diameter is fixed; IP67 rating protects the sensor but cable wear depends on installation conditions.

What limits continuous operation at the 14 m sensing range?

The 250 Hz switching frequency and 2 ms response time set the speed limit; dark-switching PNP output handles up to 100 mA per cycle.

How much heat does the sensor generate when powered at 30 V DC all day?

Power consumption is 30 mA at 10–30 V DC; the sensor operates from –25 °C to +70 °C without active cooling.
