Balluff BNS-542-B03-R12-72-10 Mechanical Position Switch

Balluff BNS-542-B03-R12-72-10 is a mechanical multi-position limit switch from Balluff's BNS family, designed to detect multiple discrete positions along a moving part with three roller-actuated switching elements. The R12 in the model name indicates a 12 mm actuation pitch, and the 72-10 form factor denotes the line of mechanical integration for this variant. The switch features an aluminum housing with anodized finish and IP67 protection for demanding industrial environments, and it terminates via screw-terminal connections for robust wiring. Rated data for comparable Balluff multi-position switches in this family commonly reach up to 6 A at 250 VAC, enabling reliable control of actuators and logic circuits across multiple positions. The operating temperature range is typically -5 to +85 C, suitable for broad factory floors and process areas. With its three outputs, this device can provide independent normally-open and normally-closed or dual-changeover configurations depending on the installed switch elements, delivering precise, repeatable position sensing along a travel path. Typical applications include end-of-travel sensing on cams and conveyors, machine-automation limit detection, and multi-point position monitoring in packaging, machining, and material-handling lines.
