The HT1256F series through-bore slip ring features a bore diameter of 12.7mm, an outer diameter of 56mm, and 1–36 channels. It is designed for equipment that requires continuous 360° rotation while transmitting power, signal, or data between stationary and rotating parts.
This series supports signal transmission at 2A, as well as power transmission at 5A or 10A, with a rated voltage of 380VAC / 24VDC. With its compact structure and flexible circuit combinations, it is suitable for small rotating systems, shaft-mounted equipment, automation machinery, rotary tables, testing systems, and other industrial applications.
Custom options are available for circuit number, current capacity, signal type, wire length, connector type, housing material, protection grade, and working environment.
