Balluff BNS519-B4R16-100-10 Programmable Limit Switch

Balluff BNS519-B4R16-100-10 Programmable Limit Switch is Balluff’s programmable position-sensing device in the BNS family, used to detect a defined mechanical position and trigger a control signal in automation systems. Designed for rugged industrial environments, this limit switch is configured to trip when a cam, plunger, or other actuator reaches the programmed travel point, enabling precise end-of-travel detection, sequencing, or interlock functions in conveyors, robotics, packaging lines, CNC machines, and other automation equipment. As part of Balluff’s multi-position and programmable BNS lineup, the BNS519 supports configurable actuation and switching behavior to suit high-cycle or safety-related applications, with compatible housings, cams, and mating cables available through Balluff’s ecosystem. The model naming—BNS519-B4R16-100-10—signals its place in the product family and supports standard electrical interfaces used in industrial controls; however, exact electrical ratings, mechanical dimensions, and configuration options are specified in Balluff’s official datasheets and catalog materials for this model. For integration, users typically pair this switch with Balluff wiring harnesses and control modules to ensure signal integrity and reliable operation within PLC or safety interlock circuits. This description reflects Balluff’s emphasis on robust, repeatable position sensing in manufacturing environments and the role of programmable limit switches in end-of-travel sensing and machine safety.
