Inductive Sensor M18, PNP NO – PRDL18-14DP

Autonics Cylindrical Inductive Long-Distance Proximity Sensor – PRDL18-14DP

Cylindrical, PNP Normally Open, Cable Type, General type

The PRDL18-14DP 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 PRDL18-14DP is available in DC 3-wire type.

As a quick report, this inductive proximity sensor provides:

• Non-shield (non-flush) installation

• 18 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 PRDL18-14DP 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 PRDL18-14DP features standard cable type connection. This cable covers the sensor’s 3 wires. It is 5 mm in diameter and 2 meters in length, and is made of PVC.

Sensing specifications

The diameter of the PRDL18-14DP sensing side is 18 mm and its sensing distance is 14 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 9.8 mm.

Also, it should always be considered that this data is reported for the secure and standard sensing target, which is an 40x40x1 mm piece made of iron, for this product.

Control output

The PRDL18-14DP features PNP Normally Open control output. PNP stands for Positive-Negative-Positive transistors.
