Balluff BNS819-X512-100-R-12-S4 Mechanical Limit Switch

Balluff BNS819-X512-100-R-12-S4 is a single‑position mechanical limit switch from Balluff’s Classic portfolio, built with an anodized aluminum housing and a roller actuator for durable mechanical actuation. It uses a snap‑contact output and a mechanical switching principle, with a continuous current rating of 0.1 A and a rated operating voltage of 25 VAC / 60 VDC. The unit is rated IP67 and operates from -5 to 85 °C, making it suitable for harsh industrial environments. It can be mounted with the approach direction either lateral or perpendicular to the mounting surface and connects via a circular 4‑pin connector on the left side. Hardened X512 bushings are used in this model to enhance longevity in repetitive end‑of‑travel cycles, aligning with its role as a reliable position sensor in conveyors, presses, and automation arms.
