SICK Retroreflective Photoelectric Sensor, Barrel Sensor, 35 mm → 4.5 m, PNP, IP67, IP68, IP69K

SICK V18 Series Photoelectric Sensor, IP67, IP68, IP69K, 30V DC Maximum DC Voltage - VL18-4P2240V

This photoelectric sensor is a retroreflective detection device designed for industrial automation environments. It detects transparent items using an LED light source and is built for continuous operation in demanding settings, providing fast signalling and a robust stainless-steel cylindrical housing suitable for threaded mounting.

Features and Benefits:

• PNP output enables simple integration with control systeMS
  4-pin M12 Terminal offers compact, secure connectivity
  Response time 1 MS delivers near-instant detection performance
  Operating range to 80°C supports high-temperature processes
  IP67 IP68 IP69K rating resists dust, water and washdowns
  Maximum current 100 mA minimises load on controllers

Applications

• Suitable for conveyor-line transparent bottle detection
  Ideal for packaging inspection in washdown environments
  Used for position sensing in automated assembly cells
  Can be used for material handling with threaded mounting
  Suitable for food production lines requiring stainless housings

What electrical supply limits should I observe?

Ensure the control circuit does not exceed 30V DC and design inputs to accommodate a sensor current draw up to 100 mA.

How is the sensor connected to a PLC or relay?

Use the 4-pin M12 Terminal with wiring for a PNP output configuration to Interface directly with standard sourcing inputs.

What environmental stresses can it tolerate?

The stainless-steel housing and ingress protection ratings allow operation under immersion and high-pressure cleaning common in industrial facilities.

What detection challenges does it address with transparent materials?

The LED light source and retroreflective arrangement improve contrast detection of clear substrates compared with diffuse sensors.
