Sumitomo Electric Industries SA765603BC Control Board

Sumitomo SA765603BC is a SXEX servo control board used in Sumitomo injection-molding equipment, described as a heavy control board within the SXEX family. The part is listed alongside related models SA765604AX and SHI SA765606AC, signaling they are variants within the same control-system lineup. Vendors categorize this board as a four-axis servo control solution for injection molding machines, designed to coordinate motion across four servo axes in concert with Sumitomo drive electronics. In aftermarket listings, the SA765603BC is often offered refurbished, serving as a practical replacement part for service and modernization of SXEX systems. Typical applications include four-axis injection molding setups that require synchronized control of multiple servo axes, with exact axis assignments and electrical interfaces determined by the specific machine configuration. Because exact specifications, pinouts, and compatibility depend on the Sumitomo model and revision, buyers should verify against the machine’s service documentation and the corresponding SXEX control-board documentation before installation. As part of Sumitomo’s servo control ecosystem, these boards connect with SXEX drives and control panels to deliver precise, responsive motion for high-volume molding operations.
