Inductive Sensor M12, PNP NO – PR12-4DP
DESCRIPTION
Autonics inductive proximity sensor M12, PNP NO – PR12-4DP
Non-shield (non-flush), Cable type connection, 4 mm Sensing distance
The Autonics inductive proximity sensor PR12-4DP 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 4mm, sensing side diameter and housing size of m12 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:
- 12 mm sensing side diameter
- PNP Normally Open control output
- 4 mm sensing distance
- Non-shield (non-flush), installation
- Improved noise resistance
- Long life cycle and simple operations
- 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 pnp 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 PR12-4DP features IP67 ingress protection.
The red LED on its body acts as the process indicator.
Connection
The Autonics proximity sensor PR12-4DP 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, and is made of PVC.
Sensing specifications
This inductive PNP proximity sensor’s sensing side diameter is 12 mm. The maximum distance that this sensor can detect its standard sensing target, which is a 12x12x1 mm piece of iron, is 4 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 2.8 mm for this proximity sensor.
Control output
The PR12-4DP features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.
Temperature
There are limitations in temperature and humidity in which PR12-4DP PNP proximity sensor is used:
