Autonics inductive proximity sensor PRA30-10DN

Cylindrical, Spatter-Resistant, High protection class

The PRA30-10DN inductive proximity sensor is PTFE coated for high heat resistance and prevention of malfunctions caused by welding spatter. This sensor also features excellent noise immunity with a specialized sensor IC developed by Autonics. The sensor is ideal for welding applications and can be used as an alternative to spatter-resistant limit switches. The PRA30-10DN is a DC 3-wire type proximity sensor.

As a quick report, this inductive proximity sensor provides:

• Shield (flush) installation
• 30 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
• Built-in reverse polarity protection circuit

Body

The PRA30-10DN case is made of PTFE coated brass, its washer is made of PTFE coated iron, and the material of its sensing side is PTFE.

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 PRA30-10DNis connector type which consists of a 4-pin M12 connector. This standard cable is black and made of PVC.

Sensing specifications

The diameter of the PRA30-10DN sensing side is 30 mm and its sensing distance is 10 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 7 mm.

Also, it should always be considered that this data is reported for the secure and standard sensing target, which is a 30x30x1 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 PRA30-10DN proximity sensor 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.
