Description

Autonics proximity sensor M18, NPN NC PR18-8DN2

Non-Shield (non-flush), Cable type connection, 8 mm Sensing distance

 

The Autonics proximity sensor PR18-8DN2 features outstanding noise protection and stable sensing performance due to its specialized sensor IC developed by Autonics. This sensor comes in a round cylindrical shape, sensing distance of 8mm, sensing side diameter and housing size of m18 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:

  • 18 mm sensing side diameter
  • NPN Normally Closed control output
  • 8 mm sensing distance
  • Non-Shield (non-flush) installation
  • Improved noise resistance
  • Built-in reverse polarity protection circuit
  • Built-in surge protection circuit
  • Built-in over-current protection circuit
  • Long life cycle and high reliability, and simple operations
  • IP67 ingress protection structure according to IEC standards
  • Red LED status indicator
  • Alternative to micro switches and limit switches.

Body

This Autonics proximity sensor's case and nut parts are made of nickel-plated brass, its sensing side is made of PBT, and its washer is nickel plated iron made.

The PR18-8DN2 features IP67 ingress protection.

The red LED on its body acts as the process indicator.

Connection

The Autonics proximity sensor PR18-8DN2 features standard cable type connection. This black cable covers the sensor's 3 wires. It is 5 mm in diameter and 2 meters in length, and is made of PVC.

Sensing specifications

This Autonics PR Series inductive sensor's sensing side diameter is 18 mm. The maximum distance that this sensor can detect its standard sensing target, which is an 25x25x1 mm piece of iron, is 8 mm. This so-called sensing distance differs from one sensing target to another, based on their material, size, etc.

Although almost no one talks about the setting distance of an inductive sensor, it is a big deal to know this concept. Every sensor can detect its standard sensing target in a specified range, no matter what changes occur in ambient temperature, voltage fluctuations, etc. This distance, which is called the setting distance, is from 0 to 5.6 mm for this proximity sensor.

Control output

The PR18-8DN2 features NPN Normally Closed control output. NPN stands for Negative-Positive-Negative transistors.

Temperature

There are limitations in temperature and humidity in which this NPN proximity sensor is used:

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

Environment resistance is rated at no freezing or condensation.

Industries / applications

  • Part detection on industrial conveyor systems
  • Automated production lines
