Contrinex High Pressure proximity sensor M8, PNP NO DW-AD-503-P8

Embeddable (flush), Cable type connection, 1.5 mm Sensing distance

The Contrinex high pressure proximity sensor DW-AD-503-P8 features outstanding noise protection and stable sensing performance due to its specialized sensor IC developed by Contrinex. This sensor comes in a round cylindrical shape, sensing distance of 1.5mm, sensing side diameter and housing size of M8, 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 high pressure proximity sensor provides:

  • 8 mm sensing side diameter
  • PNP Normally Open control output
  • 1.5 mm sensing distance
  • Embeddable (flush) installation
  • Long life cycle and simple operations
  • protections against short-circuits and induced overvoltages
  • IP68 ingress protection structure according to IEC standards
  • Yellow LED status indicator


This Contrinex high pressure proximity sensor's case and nut parts are made of Stainless-steel V4A.

The DW-AD-503-P8 features IP68 ingress protection.

The LED on its body acts as the process indicator.


The Contrinex M8 proximity switch DW-AD-503-P8 features standard cable type connection. This cable covers the sensor's 3 wires. It is 2 meters in length, and is made of PUR.

Sensing specifications

This inductive sensor's sensing side diameter is 8 mm. This sensor's maximum distance to detect its standard sensing target is 1.5 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.

Control output

The DW-AD-503-P8 features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.


The ambient temperature range that the DW-AD-503-P8 M8 proximity switch works properly in is -25 … 70°C and 70 … 100°C.

Series Information

High Pressure Proximity sensors

Contrinex HIGH PRESSURE inductive sensors are suitable for continuous duty at pressures up to 500 bar (1,000 bar peak pressure), ensuring reliable, accurate sensing in the most demanding pneumatic and hydraulic applications. Available with classic metal housing or one-piece, stainless-steel construction, high-pressure sensors detect the smallest parts and are ideal for piston-control applications where space is at a premium. An IO-Link interface is also available for communication in PNP NO versions.

High Pressure Sensors Main features

  • Extraordinary life time under pressure cycles
  • Highest operating and peak pressures (500 bar, 1000 bar peak)
  • Operating temperatures up to 100°C
  • IO-Link
