Balluff BES-515-437-S21-L-9430 Inductive Sensor

Balluff BES-515-437-S21-L-9430 Inductive Sensor is a compact Balluff induction device designed for non-contact detection of metal targets in industrial automation. As part of Balluff’s BES 515 family, it employs inductive sensing to switch its output when a metal object enters its sensing range, enabling reliable presence or position sensing on conveyors, robotic pick-and-place stations, and automated assembly lines. The model BES-515-437-S21-L-9430 identifies a specific configuration within the BES series, compatible with standard control system interfaces used in factory floors. Its rugged construction and Balluff heritage support stable operation in typical environments, including exposure to dust, coolants, and lubricants. This sensor is well suited for end-of-travel sensing on mechanical linkages, metal fixture detection, and tool presence monitoring, where precise, repeatable metal detection improves automation reliability. When integrating this device, engineers consider the target material, required sensing distance, and wiring arrangement to ensure proper mounting, wiring, and electrical compatibility with their controllers and actuators. The BES family is known for predictable switching behavior, durable housings, and Balluff’s long-standing focus on sensor reliability, helping installers achieve consistent performance in production lines and automated equipment.
