The Autonics PRDT30-25DO is a reliable M30 long-distance inductive sensor designed for accurate detection of large metal targets up to 25mm. This non-shielded model supports a DC 2-wire system with an operating voltage range of 12–24VDC. It offers a Normally Open output with minimal leakage current, rated at just 0.6mA, ensuring efficient integration into industrial control circuits. With a standard target size of 75Γ—75Γ—1mm (iron) and a response frequency of 100Hz, this sensor provides consistent switching and real-time detection feedback in demanding environments.

Engineered with a nickel-plated brass housing and a durable build, the PRDT30-25DO performs reliably in harsh industrial setups. Its IP67-rated protection safeguards against dust and low-pressure water jets, making it suitable for use in dusty workshops and semi-wet process areas. The sensor maintains stability within a temperature range of -25Β°C to 70Β°C and supports humidity levels up to 95% RH. With a residual voltage of max. 3.5V, it minimizes electrical noise in control panels. Designed for long-distance metal detection, this sensor is part of the proven Autonics Proximity Sensors family. For additional solutions and controller integration, refer to Autonics Sensors and Controllers.

In high-vibration environments where traditional sensors may trigger false signals, the PRDT30-25DO maintains detection stability. Panel builders benefit from its 2-wire design which simplifies wiring, and service technicians appreciate the robust body which reduces sensor failures in the field. Training centers often include this model in curriculum-based automation kits to teach real-world industrial applications involving longer detection zones. Whether used in machinery control, material handling, or part positioning, the Autonics PRDT30-25DO delivers dependable sensing over extended distances.
