Technical Specifications: The PRDT18-7DO features a flush-type M18 sensing head with a 7mm sensing distance, optimized for standard 20Γ20Γ1mm iron targets. Operating on DC 2-wire 12β24VDC, it ensures low leakage current under 0.6mA and residual voltage below 3.5V, delivering accurate and stable control output with Normally Open operation. Its response frequency of 250Hz supports medium-speed automation tasks efficiently.
Performance & Reliability: Engineered with a nickel-plated brass body and IP67 protection, this Autonics Proximity Sensor resists dust, moisture, and oil, maintaining reliability in harsh industrial environments. It operates seamlessly in temperatures ranging from -25Β°C to 70Β°C and humidity from 35% to 95% RH. Compact and lightweight (~97g), the sensor withstands long-term use with minimal maintenance, ensuring uninterrupted operation on production lines and conveyor systems.
Applications & Use Cases: Widely used in automated conveyors, part feeders, press machines, and jig detection, the PRDT18-7DO guarantees precise detection before machine start-up or tool engagement. Maintenance engineers value its simple plug-and-play wiring and low failure rate. In dusty, high-vibration, or die-casting shop environments, it prevents false triggers, reduces downtime, and improves safety interlocks. Engineering students also use this model for learning industrial-grade non-contact sensing principles in lab conditions.
