The Autonics PR08-2DN is a standard cylindrical inductive proximity sensor for reliable non-contact detection of metal objects in industrial automation. Its 8 mm diameter metal housing and 2 mm sensing distance ensure stable detection of ferrous targets and easy mounting on machines. It uses a NPN output with normally open switching, providing reliable low-side switching for controller inputs. Built-in protection against reverse polarity and short circuits extends service life, and the sealed, rugged body resists dust, oil and vibration. With stable repeatability and fast response, the PR08-2DN supports precise positioning, presence detection and counting in packaging, conveying and metalworking equipment.
