Description

Autonics PRA12-2AC - Inductive Proximity Sensor

Cylindrical Spatter-Resistant Inductive Proximity Sensor (Cable Type)

Wire type and power: AC 2-wire type, 100-240VAC~
Sensing side diameter: M12
Sensing distance: 2mm
Installation: Shield (flush)
Standard sensing target: 12×12×1mm (iron)

The PRA series inductive proximity sensors are PTFE coated for high heat resistance and prevention of malfunctions caused by welding spatter. The sensors also feature excellent noise immunity with a specialized sensor IC developed by Autonics. The sensors are ideal for welding applications and can be used as an alternative to spatter-resistant limit switches. The PRA series is available in DC 2-wire, DC 3-wire, AC 2-wire types.
