Rectangular Proximity Sensor 25 mm, NPN NO – PFI25-8DN
DESCRIPTION
Autonics proximity sensor 25mm, NPN NO PFI25-8DN
Rectangular, Cable type connection, 8 mm Sensing distance
The Autonics PFI Series proximity sensor PFI25-8DN features outstanding noise protection and stable sensing performance due to its specialized sensor IC developed by Autonics. This proximity sensor comes in a rectangular shape, sensing distance of 8mm, sensing side diameter and frame size 25mm and Rectangular installation. The standard square inductive proximity 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 Open 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 flat proximity sensor’s case and nut parts are made of Poly Phenylene Sulfide.
The PFI25-8DN features IP67 ingress protection.
The red LED on its body acts as the process indicator.
Connection
The Autonics proximity sensor PFI25-8DN features standard cable type connection. This 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 square inductive proximity 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 PFI25-8DN features NPN Normally Open control output. NPN stands for Negative-Positive-Negative transistors.
Temperature
There are limitations in temperature and humidity in which PFI25-8DN flat 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.
