Weld Immune Proximity Sensor M12, PNP NC, Flush – PRDACM12-4DP2

Autonics Cylindrical Inductive Long-Distance Sensor M12, PNP NC – PRDACM12-4DP2

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

The Autonics proximity sensor PRDACM12-4DP2 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 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 Closed control output

• 4 mm sensing distance

• Shield (flush) installation

• 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.

• Spatter-resistant type: PTFE coated for high heat resistance (prevent malfunction from welding spatter)

Body

This proximity sensor’s case and nut parts are made of Brass (teflon coated).

The PRDACM12-4DP2 features IP67 ingress protection.

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

Connection

The Autonics cylindrical sensor PRDACM12-4DP2 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 PRDACM12-4DP2 features PNP Normally Closed control output. PNP stands for Positive-Negative-Positive transistors.
