Contrinex proximity sensor M12, PNP NO - DW-AS-503-M12

Quasi-embeddable (flush), M12 4-pin, 6 mm Sensing distance

The Contrinex 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 6mm, sensing side diameter and housing size of M12, 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:

  • 12 mm sensing side diameter
  • PNP Normally Open control output
  • 6 mm sensing distance
  • Quasi-embeddable (flush) installation
  • Long life cycle and simple operations
  • protections short-circuits and voltages reversal
  • IP67 ingress protection structure according to IEC standards
  • Yellow LED status indicator


This M12 flush prox sensor's case and nut parts are made of Chrome-plated brass.

The DW-AS-503-M12 features IP67 ingress protection.

The LED on its body acts as the process indicator.


The M12 flush prox sensor DW-AS-503-M12 features a 4-pin M12 electrical connection.

Sensing specifications

This inductive sensor's sensing side diameter is 12 mm. This sensor's maximum distance to detect its standard sensing target is 6 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-AS-503-M12 features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.

Industries / applications:

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

Series Information

BASIC Proximity sensors

Contrinex BASIC inductive sensors have a worldwide and well-deserved reputation for uncompromising accuracy and exceptional reliability. With best-in-class sensing distances between 1.5 mm and 40 mm, the Contrinex BASIC range offers fit-and-forget operation, delivering world-class performance and a highly attractive total cost of ownership. Available in sizes from M8 to M30 and C44, with optional Ø 6.5 plain and 8 mm square-section models, BASIC range inductive sensors are ideal for general position-sensing and presence-sensing applications in almost any industry. Embeddable or non-embeddable variants are available, with either hard-wired, hermetically sealed connecting cables or integral metal connectors. BASIC range devices, whether from the conventional Classics, or the advanced Extra Distance or Full Inox technology families, all utilize Contrinex application-specific integrated circuits (ASICs) that ensure highly repeatable results at operating temperatures between -25°C and +70°C. An IO-Link interface is also available for communication in PNP NO versions.

BASIC Sensors Main features

  • Excellent price performance ratio
  • Deviation in operating distance ≤2%
  • Outstanding temperature compensation
  • IO-Link
