Contrinex proximity sensor M18, 2-wire NC DW-AD-608-M18

Embeddable (flush), Cable type connection, 5 mm Sensing distance

The Contrinex proximity sensor DW-AD-608-M18 features outstanding noise protection and stable sensing performance due to its specialized sensor IC developed by Contrinex. This 2 wire proximity sensor comes in a round cylindrical shape, sensing distance of 5mm, sensing side diameter and housing size of M18, and shield (flush) installation. The standard cylindrical inductive sensor can be used in diverse applications requiring non-contact detection of metallic objects.

As a quick report, this inductive proximity sensor provides:

  • 18 mm sensing side diameter
  • 2-wire Normally Colsed control output
  • 5 mm sensing distance
  • Embeddable (flush) installation
  • Long life cycle and simple operations
  • protections Induction built-in
  • IP67 ingress protection structure according to IEC standards
  • Yellow LED status indicator


This Contrinex proximity sensor's case and nut parts are made of Chrome-plated brass and its sensing side is made of PBTP (Crastin).

The DW-AD-608-M18 features IP67 ingress protection.

The LED on its body acts as the process indicator.


The Contrinex proximity sensor DW-AD-608-M18 features standard cable type connection. This cable covers the sensor's 2 wires. It is 2 meters in length, and is made of PVC.

Sensing specifications

This inductive sensor's sensing side diameter is 18 mm. This sensor's maximum distance to detect its standard sensing target, which is a 18x18x1 mm piece of iron, is 5 mm. This so-called sensing distance differs from one sensing target to another, based on their material, size, etc. You could find out the sensing distance in Contrinex proximity sensors with a correction factor, mentioned in their datasheet.

This 2 wire proximity sensor also features 0.5 mm repeat accuracy.

Control output

The DW-AD-608-M18 features 2-wire Normally Colsed control output.


The ambient temperature range that the DW-AD-608-M18 2 wire proximity sensor works properly in is -25 … 70°C.

Industries / applications:

  • Tool selection automated production lines
  • Robotic position-sensing
  • Control of micro-mechanisms
