Rectangular Proximity Sensor 25 mm, NPN NC – PSN25-5DN2

Autonics proximity sensor 25mm, NPN NC PSN25-5DN2

Rectangular, Cable type connection, 5 mm Sensing distance

The Autonics proximity sensor PSN25-5DN2 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 5mm, sensing side diameter and frame size 25mm and rectangular installation. The standard rectangular 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

• 5 mm sensing distance

• Rectangular installation

• Shorten the time of maintenance with the body

• Improved noise resistance

• Long life cycle and high reliability

• 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 Heat-resistant ABS. 

The PSN25-5DN2 features IP67 ingress protection.

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

Connection

The Autonics proximity sensor PSN25-5DN2 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 Autonics PS Series inductive sensor’s frame size is 25mm. The maximum distance that this sensor can detect its standard sensing target, which is a 25×25×1 mm piece of iron, is 5 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 3.5 mm for this proximity sensor.

Control output

The PSN25-5DN2 features NPN Normally Closed control output. NPN stands for Negative-Positive-Negative transistors.
