Description

Autonics proximity sensor 25mm, NPN NC - PFI25-8DN2

Flat, Cable type connection, 8 mm Sensing distance

 

The Autonics proximity sensor PFI25-8DN2 features outstanding noise protection and stable sensing performance due to its specialized sensor IC developed by Autonics. This sensor comes in a rectangular shape, sensing distance of 8mm, sensing side diameter and frame size 25mm and rectangular installation. The standard Flat inductive sensor can be used in diverse applications requiring non-contact detection of metallic objects.

As a quick report, this inductive proximity sensor provides:

  • 25 mm frame size
  • NPN Normally Closed control output
  • 8 mm sensing distance
  • Improved noise resistance
  • Easy to mount in narrow space by Flat structure
  • Reverse polarity, surge, and over-current protection
  • 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 Poly Phenylene Sulfide.

The PFI25-8DN2 features IP67 ingress protection.

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

Connection

The Autonics proximity sensor PFI25-8DN2 features standard cable type connection. This black cable covers the sensor's 3 wires. It is 4 mm in diameter and 2 meters in length.

Sensing specifications

This inductive sensor's frame size diameter is 25 mm. The maximum distance that this sensor can detect its standard sensing target, which is a 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 PFI25-8DN2 features NPN Normally Closed control output. NPN stands for Negative-Positive-Negative transistors.

Temperature

There are limitations in temperature and humidity in which PFI25-8DN2 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

  • Detect the presence of metal plates in metal processing and manufacturing
  • Automation system example of an elevator, escalator, and parking system
