Description

Autonics inductive proximity sensor M18, NPN NO - PR18-8DN

Non-shield (non-flush), Standard body length, DC 3-wire type

The PR18-8DN inductive proximity sensor features great noise immunity and stable sensing performance with a specialized sensor IC developed by Autonics. The standard cylindrical inductive sensor, which is available in m18 size and 8 mm sensing distance, can be used in various applications requiring non-contact detection of metallic objects. The PR18-8DN is available in DC 3-wire type.

As a quick report, this inductive proximity sensor provides:

  • 18 mm sensing side and body diameter
  • Improved noise resistance with dedicated IC
  • 0 to 5.6 mm setting distance
  • Long life cycle and simple operations
  • Non-shield (non-flush) installation
  • Reverse polarity, surge and over-current protection
  • Cable type connection
  • IP67 rated ingress protection structure according to IEC standards
  • Red LED status indicator
  • alternative to micro switches and limit switches.

Body

The case and nut parts of the PR18-8DN inductive sensor is made of nickel plated brass, its sensing side is made of PBT, and its washer is nickel plated iron made.

According to IEC standards, this sensor's protection structure is IP67. That means it is possible to use this proximity sensor under water with maximum depth of 1 meter for at most half an hour.

There is a red LED on this sensor's body as the operation indicator.

Connection

The PR18-8DN connection is cable type. This standard black cable is 5 mm in diameter and 2 meters in length. The cable is made of PVC and covers the sensor's 3 wires.

Sensing specifications

This inductive sensor's sensing side diameter is 18 mm. There is a maximum distance from the sensing side in which inductive proximity sensors can detect their standard sensing target. This so called sensing distance, is 8 mm for the PR18-8DP. The sensing distance differs from one sensing target to another based on the target's dimensionmaterial, etc. Standard sensing target of the PR18-8DN is a 25x25x1 mm iron made piece.

Although almost no one talks about the setting distance of an inductive proximity sensor, it is a big deal, and the user must know that there is a range in which the sensor detects its standard sensing target no matter what changes happen in ambient temperaturevoltage fluctuations, etc.

Control output

 This inductive proximity sensor's control output is NPN Normally Open, which means there would be no voltage on the output as the sensor is not actuated.

Temperature

There are limitations in temperature and humidity in which this M18 NPN NO inductive sensor is used:

  • Ambient temperature: -25 … 70°C
  • Ambient humidity: 35 to 95%RH
  • Storage temperature: -30 … 80°C
  • Storage humidity: 35 to 95%RH

Environment resistance is rated at no freezing or condensation.

Industries / applications:

  • Automated production lines
  • Part detection on industrial conveyor systems
