Balluff BES-517-140-U5-H Inductive Proximity Switch

The Balluff BES-517-140-U5-H is a cube‑style inductive proximity switch with a 50 mm nominal sensing distance, designed for reliable, non‑contact detection of metallic targets in tight automation spaces. It measures 80 × 80 × 40 mm and uses a PBT housing with a PBT sensing face, featuring a 4‑pin screw‑terminal connection and NPN switching in NO/NC configurations. The device operates from 10–55 V DC and draws up to 200 mA, with an IP67 rating for dust and water protection and an operating temperature range of −25 to 70 °C. This model belongs to Balluff’s BES 517‑140 family of 50 mm cube inductive sensors and is well suited for applications such as presence or position sensing on conveyors, end‑of‑travel detection, and fixture alignment where robust, field‑bus compatible switching is required.
