Balluff BNS 813-D02-D12-100-20-01-FD Mechanical Limit Switch

Balluff BNS 813-D02-D12-100-20-01-FD is a mechanical limit switch in Balluff’s 100-series designed for precise position sensing in automation. It provides two switching positions (2x chisel plungers) with snap-action contacts arranged as DPST (one normally open and one normally closed per position), delivering reliable feedback for control and safety circuits. The unit arrives pre‑assembled with a wiring chamber and screw‑clamp termination, and it uses an M25 cable entry for cabling; it is intended for vertical mounting in a rectangular aluminum, anodized housing measuring 120 x 70 x 85 mm with 12 mm switch spacing. LED function signaling operates from a 6–60 V control supply to indicate contact status. On the electrical side, switch 1–2 is rated up to 250 V AC, making it suitable for line-level signaling and control tasks in industrial environments. This Balluff BNS813 family device functions as a dual-position mechanical limit switch with integrated safety switching features, ideal for cam-operated applications that require clear status indication and robust mounting with feet for secure installation.
