The Keyence EH-422 is an inductive proximity sensor designed to deliver reliable, long-range detection with outstanding precision and durability. As a standard, non-shielded cylindrical sensor, it provides extended sensing distances compared to shielded models, making it a versatile choice for applications requiring more detection flexibility. The threaded body design ensures simple integration into existing systems while maintaining robust performance in various industrial environments.

One of the standout features of the EH-422 is its extended sensing capability. With a stable detecting range of 0 to 9 mm and a maximum detecting distance of 18 mm, it provides consistent detection of ferrous metals, such as steel and iron. This makes it ideal for use in applications like conveyor systems, automated machinery, and metal component assembly lines, where reliable object detection is crucial for operational efficiency. The sensor is also capable of detecting non-ferrous metals with adjusted characteristics, further broadening its usability.

In terms of precision, the EH-422 excels with a hysteresis of just 0.06 mm and repeatability of 0.02 mm, ensuring highly accurate measurements and stable outputs. This level of accuracy reduces false detections and supports applications that demand tight tolerances, such as in robotics, positioning, or precision machining. Its temperature characteristics also guarantee consistent detection performance within ±10% of the rated distance, even under varying conditions between -10°C and +60°C, making it reliable in fluctuating environments.

Durability is another strength of the EH-422. The sensor is built with a rugged structure and comes with an IP67 enclosure rating, meaning it is resistant to dust ingress and water immersion. This enables it to perform reliably in harsh industrial conditions where exposure to moisture, oil, or dust may otherwise compromise performance. The sensor also withstands humidity ranges of 35 to 85% without condensation, extending its lifetime and reducing maintenance requirements.

Weighing approximately 175 g, including its nuts and 3-meter cable, the EH-422 is compact yet sturdy. This lightweight yet strong construction ensures easy installation without compromising robustness. The included cable provides flexible wiring options, making it easier for engineers to integrate the sensor into complex systems.

In summary, the Keyence EH-422 Inductive Proximity Sensor combines extended detection capability, high precision, rugged durability, and reliable performance in varied environments. These qualities make it an ideal solution for demanding applications where long-range detection, accuracy, and robustness are essential to maintaining productivity and efficiency.
