Contrinex Full Metal proximity sensor M18, NPN NO DW-AD-701-M18

Embeddable (flush), Cable type connection, 10 mm Sensing distance

The Contrinex full metal proximity sensor DW-AD-701-M18 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 10mm, 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 full metal proximity sensor provides:

  • 18 mm sensing side diameter
  • NPN Normally Open control output
  • 10 mm sensing distance
  • Embeddable (flush) installation
  • Long life cycle and simple operations
  • protections against short-circuits and voltages reversal
  • IP 68 / IP 69K ingress protection structure according to IEC standards
  • Yellow LED status indicator


This Contrinex full metal proximity sensor's case and nut parts are made of Stainless-steel V2A and its sensing side is made of Stainless-steel V2A.

The DW-AD-701-M18 features IP 68 and IP 69K ingress protection.

The LED on its body acts as the process indicator.


The Contrinex M18 NPN prox sensor DW-AD-701-M18 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 18 mm. This sensor's maximum distance to detect its standard sensing target, which is a 30x30x1 mm, FE360 piece of iron, is 10 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 M18 NPN prox sensor also features ≤ 0.3 mm repeat accuracy.

Control output

The DW-AD-701-M18 features NPN Normally Open control output. NPN stands for Negative-Positive-Negative transistors.


The ambient temperature range that the DW-AD-701-M18 M18 NPN prox sensor works properly in is -25 … 85°C.

EXTREME Proximity sensors

Only the toughest sensors survive the most extreme environments, and Contrinex EXTREME inductive sensors from the Full Inox family are ideally equipped for the job. Thanks to one-piece stainless-steel (V2A/AISI 303) construction and a hermetically sealed cable entry, Extreme sensors are corrosion-resistant, impervious to oil, and pressure-resistant to 100 bar. Rugged, reliable and highly accurate, the EXTREME range is at home in the most challenging circumstances.

Developed to withstand the harshest industrial operating conditions, Extreme sensors are rated to IP 68 and IP 69K, delivering fit-and-forget performance with minimal downtime. With operating distances up to 40 mm, the Extreme range senses both ferrous and non-ferrous materials with Factor 1 performance, and is available in sizes from M8 to M30 and C23.

EXTREME Sensors Main features

  • World class performance in extreme environments
  • Extremely robust one-piece, stainless-steel housing
  • Factor 1 with both ferrous and non-ferrous materials
