PRT08-1.5DO Autonics Proximity Sensor
Autonics PRT08-1.5DO Inductive Proximity Sensor – M8, 1.5 mm, NPN, DC 3-Wire
Autonics PRT08-1.5DO is an ultra-compact M8 inductive proximity sensor with 1.5 mm sensing distance and NPN DC 3-wire output.
Designed for precise metal detection in PLC-controlled compact automation systems.
The Autonics PRT08-1.5DO is a miniature cylindrical inductive proximity sensor engineered to detect metal objects only in space-constrained industrial automation environments. With its M8 threaded housing, 1.5 mm sensing distance (flush type), and NPN DC 3-wire normally open output, it ensures fast, stable, and repeatable detection for PLC panels, compact machines, jigs, and fixtures.
