The Autonics PRDT12-8DO Long-Distance Inductive Sensor offers extended sensing performance with a non-shielded M12 sensing side and an impressive 8mm sensing distance, making it suitable for detecting larger metal targets like 25Γ25Γ1mm iron plates. It operates on a DC 2-wire 12β24VDC supply and delivers a Normally Open control output, supporting flexible logic circuits in both relay-based and PLC-controlled systems. Designed with a maximum leakage current of 0.6mA and residual voltage of 3.5V, it ensures energy-efficient switching and stable performance in signal-sensitive environments.
This model features a rugged brass body with nickel plating for corrosion resistance and long-term durability. The IP67 protection rating ensures safe operation in dust, oil mist, and wet conditions, while the ambient operating range of -25Β°C to 70Β°C supports use in both indoor and semi-exposed installations. With a response frequency of 400Hz, the sensor can handle fast-moving production lines without missing signals. Itβs built to support uninterrupted performance, whether mounted horizontally on metal frames or vertically on adjustable brackets.

The PRDT12-8DO is widely used in assembly lines, press machines, conveyor systems, and jig detection applications where longer sensing distance with high-speed output is required. Maintenance engineers prefer it in equipment where sensors must detect objects at a distance without mechanical contact, reducing wear and increasing service life. In packaging units, it is used to ensure metal tray or component presence before initiating filling or sealing cycles. For junior engineers and students in automation labs, it offers a practical example of how 2-wire DC sensors can be integrated into real-time control systems. With minimal wiring, precise detection, and robust protection, this sensor supports preventive maintenance and error-free sensing for smooth plant operations.
