Balluff BES-516-343E3L Inductive Proximity Sensor

Balluff BES-516-343E3L is a tubular, 3‑wire DC inductive proximity sensor from Balluff's BES 516 family, offering a compact metal‑cased design with a 1.50 mm nominal sensing distance for metal‑target detection. It provides a normally open NPN output and operates on 10–30 V DC, with a 5 m cable lead suitable for remote mounting and standard automation wiring. Its flush, shielded installation and IP68 rating ensure reliable service in harsh industrial environments, making it well suited for end‑of‑stroke or position sensing on conveyors and automated assemblies. The device aligns with IEC 60947‑5‑2 and carries CE, cULus, and EAC approvals; it supports a maximum load capacitance of 0.5 µF and a no‑load current up to 3 mA, with a functional indicator to aid diagnostics. Typical applications include detecting metal targets in tight spaces where a compact, dependable proximity sensor is required, such as machine tools, packaging lines, or robotic grippers, where a 1.5 mm sensing distance helps ensure precise actuation without misdetection.
