Contrinex proximity sensor M30, PNP NO - DW-AS-633-M30-002

Non-embeddable (non-flush), M12 4-pin, 25 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 25mm, sensing side diameter and housing size of M30, and Non-shield (non-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:

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


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

The DW-AS-633-M30-002 features IP67 ingress protection.

The LED on its body acts as the process indicator.


The Contrinex proximity sensor DW-AS-633-M30-002 features a 4-pin M12 electrical connection.

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 75x75x1 mm, FE 360 piece of iron, is 25 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 M30 PNP NO proximity switch also features 0.75 mm repeat accuracy.

Control output

The DW-AS-633-M30-002 features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.


The ambient temperature range that the DW-AS-633-M30-002 M30 PNP NO proximity switch works properly in is -25 … 70°C.

Industries / applications:

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

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
