The BALLUFF BES01H0 (BES 516-355-S4-C) is a cylindrical inductive proximity sensor designed for reliable, non-contact metal detection in industrial automation environments. Featuring a compact M18×1 threaded housing with overall dimensions of 18 × 83 mm, it supports easy installation in shielded (flush-mounted) configurations. The sensor provides a 5 mm nominal sensing range, ensuring precise and repeatable detection performance across standard metallic targets. It is equipped with an NPN normally open (NO) switching output, allowing direct integration with control circuits and PLC input modules. Engineered for durability and consistent operation, the BALLUFF BES01H0 sensor delivers stable switching behavior and strong electromagnetic compatibility. This inductive sensor could potentially be utilized across North America, Europe, Asia, and other industrial regions where robust, shielded M18 proximity sensing with NPN output and 5 mm detection range is required.
