English Product Introduction
The PR08-2DN is an inductive proximity sensor operating on 12-24VDC, featuring NPN normally-open configuration with 3-wire connection. This cylindrical sensor detects ferrous metal targets within 2mm range through electromagnetic field variation, generating eddy currents that alter oscillation parameters when metal objects approach. With compact M8 housing (8mm diameter), it suits space-constrained installations in industrial automation systems.116
Key Features
This non-contact switch eliminates mechanical wear with rapid response (500Hz switching frequency) and long service life. Built-in protections include reverse polarity safeguard (DC models) and voltage fluctuation resistance. The IP67-rated housing withstands dust and temporary immersion, operating reliably in -20°C to 70°C environments. Standard 2-meter cable follows color-coded wiring: brown (+V), blue (0V), and black (signal output). Both flush and non-flush mounting options are supported.2818
Typical Applications
Ideal for position sensing in CNC machines, conveyor systems, and robotic arms, the sensor performs metal part detection, object counting, and end-position control. Common implementations include elevator leveling, packaging line monitoring, and automated assembly verification. Its sealed construction also suits food processing equipment and printing machinery where liquid splash or powder exposure occurs.6924
Performance Advantages
Compared to mechanical limit switches, this solid-state device offers higher repeat accuracy (±0.1mm) and vibration resistance, supporting up to 800 operations per second. The optimized coil design from AUTONICS ensures stable performance even in environments with metal chips interference. Variants with different sensing ranges (1.5mm/2mm) and threaded lengths are available for flexible integration.111926
