Inductive Sensor M12, NPN NO – PRD12-8DN

Autonics inductive proximity sensor PRD12-8DN

Cylindrical, NPN Normally Open, Cable Type

The PRD12-8DN inductive proximity sensor features long sensing distances and excellent noise immunity with a specialized sensor IC developed by Autonics. The connector type sensor offers easier maintenance and wiring work. This high performance cylindrical inductive sensor can be used in diverse applications requiring non-contact detection of metallic objects. The PRD12-8DN is available in DC 3-wire type.

As a quick report, this cylindrical inductive sensor provides:

• Non-shield (non-flush) installation

• 12 mm sensing side diameter

• 3-wire cable connection

• Simple operation, reliable performance, and high durability

• Operation indicator (red LED)

• Durable and reliable alternative to micro switches and limit switches

• Built-in surge protection circuit

• Built-in overcurrent protection circuit

• Built-in reverse polarity protection circuit

Body

The PRD12-8DN long body size case is made of nickel-plated brass, its washer is made of nickel-plated iron, and the material of its sensing side is PBT.

Protection structure of this proximity sensor is IP67 (IEC standard).

This sensor has a red LED as the operation indicator on its body.

Connection

Connection of the PRD12-8DN is Cable Type, which contains a cable covering its 3 wires.This standard cable is black and made of PVC.

Sensing specifications

The diameter of the PRD12-8DN sensing side is 12 mm and its sensing distance is 8 mm. Although almost no one talks about the setting distance of an inductive sensor, it should be announced that for this sensor, it is 0 to 5.6 mm.

Also, it should always be considered that this data is reported for the secure and standard sensing target, which is an 25x25x1 mm piece made of iron, for this product.

Control output

The control output of the case study proximity sensor is NPN Normally Open.

Temperature

There are limitations in environment temperature and humidity in which this proximity switch NPN NO is used:

• Ambient temperature: -25 … 70°C

• Ambient humidity: 35 to 95%RH

• Storage temperature: -30 … 80°C

• Storage humidity: 35 to 95%RH

Environment resistance is rated at no freezing or condensation.

It’s better not to use this product outside of these ranges, in order to keep it stable.
