Balluff BES-517-347-M1-Z5 Inductive Proximity Sensor

Balluff BES-517-347-M1-Z5 Inductive Proximity Sensor is a compact, non-contact sensing device designed to detect metal targets on automation lines. As part of Balluff’s BES family, it uses inductive technology to switch when a metal object enters its field, providing reliable presence or position sensing without wear. Verified retailer listings for BES-517-347-M1 variants show a 2 mm sensing distance, a current draw of about 130 mA, and a DC supply range of 10–30 V, making it compatible with common industrial control circuits. The M1 form factor supports installation in tight spaces, and the inherent benefits of inductive sensing—no moving parts and resistance to dirt and contamination—help ensure long-term, maintenance-free operation in typical manufacturing environments. This model is suited for applications such as detecting the presence of metal components on conveyors, verifying part presence in assembly lines, and other short-range metal-detection tasks where precise, repeatable switching is required. Balluff's BES sensors are known for repeatable performance and consistent electrical interfaces across the family, which simplifies integration with PLCs and controllers. The BES-517-347-M1-Z5 variant provides the same core sensing technology and electrical characteristics as other BES 517-series devices while offering a specific form factor and connector option to fit tight installation spaces.
