Inductive Sensor M12, PNP NO, Flush – PRDCM12-4DP

Autonics proximity sensor M12, PNP NO PRDCM12-4DP

Shield (flush), Long distance, 4 mm Sensing distance

The cylindrical inductive sensor PRDCM12-4DP 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 shield (flush) installation. The standard 12v proximity switch 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

• Shield (flush) installation

• Improved noise resistance

• Long sensing distance

• Easy to check operation from various angle with 4-side LED

• Advanced durability as comprehensive existing case and rear cap structure

• Shorten the time of maintenance

• Built-in surge protection, reverse polarity protection and over-current protection circuit

• 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 nickel-plated brass. The PRDCM12-4DP features IP67 ingress protection.

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

Connection

The Autonics proximity sensor PRDCM12-4DP features standard cable type connection. This cable covers the sensor’s 3 wires.

Sensing specifications

This inductive 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 PRDCM12-4DP features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.

Temperature

There are limitations in temperature and humidity in which PRDCM12-4DP 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.
