Contrinex Analog proximity sensor M30, Voltage/Current output DW-AS-509-M30-390

Quasi-embeddable, M12 4-pin, 0 To 20 mm sensing distance

The Contrinex analog proximity sensor DW-AS-509-M30-390 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 0 To 20 mm, 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 analog proximity sensor provides:

  • 30 mm sensing side diameter
  • Voltage/Current output
  • 0 to 20 mm sensing distance
  • Quasi-embeddable (flush) installation
  • Long life cycle and simple operations
  • protections against short-circuits and voltage reversal
  • IP67 ingress protection structure according to IEC standards


This Contrinex analog proximity sensor's case and nut parts are made of Chrome-plated brass.

The DW-AS-623-M5 features IP67 ingress protection.


The Contrinex analog 30mm proximity sensor DW-AS-509-M30-390 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 piece of iron, is 0 to 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 proximity sensors with a correction factor, mentioned in their datasheet.

Control output

The DW-AS-509-M30-390 features Voltage/Current Analog control output with switching frequency of 200 Hz and the input for this analog proximity sensor is 15 to 30 VDC.


The ambient temperature range that the DW-AS-509-M30-390 analog 30mm proximity sensor works properly in is -25 … 70°C.
