Inductive Sensor M18, PNP NO, Flush – PRD18-7DP
DESCRIPTION
Autonics inductive proximity sensor M18, PNP NO – PRD18-7DP
Shield (flush), Long distance, 7 mm Sensing distance
The Autonics proximity sensor PRD18-7DP features outstanding noise protection and stable sensing performance due to its specialized sensor IC developed by Autonics. This proximity detector comes in a round cylindrical shape, sensing distance of 7mm, sensing side diameter and housing size of m18 and Shield (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 cylindrical inductive sensor provides:
- 18 mm sensing side diameter
- PNP Normally Open control output
- 7 mm sensing distance
- Shield (flush) installation
- Longer sensing distance up to 25mm
- Improved noise resistance
- Long life cycle and reliable
- 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 proximity sensor’s case and nut parts are made of nickel-plated brass. The PRD18-7DP features IP67 ingress protection.
The red LED on its body acts as the process indicator.
Connection
The Autonics proximity detector PRD18-7DP features standard cable type connection. This cable covers the sensor’s 3 wires.
Sensing specifications
This inductive sensor’s sensing side diameter is 18 mm. The maximum distance that this Autonics proximity detector can detect its standard sensing target, which is a 20x20x1 mm piece of iron, is 7 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 4.9 mm for this proximity sensor.
Control output
The PRD18-7DP features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.
