Contrinex High Protection proximity sensor M30, PNP NO DW-LD-703-M30

Embeddable (flush), Cable type connection, 20 mm Sensing distance

The Contrinex high protection proximity sensor DW-AS-623-M5 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 20mm, sensing side diameter and housing size of M30, 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 protection proximity sensor provides:

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


This Contrinex high protection proximity sensor's case and nut parts are made of Stainless-steel V4A and its sensing side is made of V4A.

The DW-LD-703-M30 features IP 68, IP 69K ingress protection.

The LED on its body acts as the process indicator.


The Contrinex high protection proximity sensor DW-LD-703-M30 features standard cable type connection. This cable covers the sensor's 3 wires. It is 2 meters in length, and is made of TPE-S.

Sensing specifications

This inductive sensor's sensing side diameter is 30 mm. This sensor's maximum distance to detect its standard sensing target, which is a 60x60x1 mm, FE360 piece of iron, is 20 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 washdown sensors with a correction factor, mentioned in their datasheet.

This sensor also features ≤ 0.7 mm repeat accuracy.

Control output

The DW-LD-703-M30 features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.


The ambient temperature range that the DW-LD-703-M30 high protection proximity sensor works properly in is -25 … 85°C.

Industries / applications:

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

Series Information

WASHDOWN Proximity sensors

WASHDOWN inductive sensors are certified to operate continuously and reliably in the harsh conditions of the food, beverage and pharmaceutical industries, ensuring uninterrupted production. With Ecolab approval and rated to IP 68 and IP 69K, they are pressure resistant up to 80 bar, food safe and corrosion resistant. WASHDOWN sensors are available in conventional Classics technology, size M12, or Full Inox technology, sizes M12, M18 and M30. Full Inox types have a totally impervious one-piece housing in stainless-steel (V4A / AISI 316L), including the sensing face. They are therefore highly resistant to the corrosive chemicals used for clean-in-place or wash-down processes. With Factor 1 on steel and aluminum and extended sensing ranges up to 40 mm, Full Inox technology minimizes the possibility of impact damage – a common hazard in confined operating spaces. WASHDOWN sensors meet the increasingly demanding sensing needs of the food, beverage and pharmaceutical industries, delivering best-in-class performance with an attractive total cost of ownership.

WASHDOWN Sensors Main features

  • Rated to IP68 and IP69K, ECOLAB®-certified
  • Extended sensing ranges of up to 40mm
  • One-piece stainless-steel (V4A/AISI 316L) housings
