DSTI ESM440 44-Channel High-Density Hybrid Slip Ring (10A Power + 2A Signal)
The DSTI ESM440 is a high-density 44-circuit hybrid capsule slip ring engineered to provide a robust and versatile interface for complex rotating systems. This advanced model integrates four 10A high-power circuits with forty 2A precision signal channels, allowing for the simultaneous transmission of heavy electrical loads and sensitive data within a single 89 mm [3.500"] capsule. Featuring premium gold-on-gold contact technology, the ESM440 ensures ultra-low electrical noise and maximum signal integrity during 360° continuous rotation at speeds up to 250 RPM. With its extended 1219 mm silver-plated copper leads and maintenance-free design, it is an ideal solution for large-scale robotics, sophisticated industrial machinery, and high-specification automated control systems.
