Insufficient Space Inside Your Turntable? Try JINPAT Slip Rings!

Engineers engaged in turntable design commonly face a shared pain point: customer demands for functionality are becoming increasingly diverse. Beyond traditional power supply and encoder connections, modern requirements have expanded to include Gigabit Ethernet, CAN bus, and multiple analog sensor channels. However, the central through-hole of the turntable remains frustratingly narrow, and the housing dimensions are strictly fixed—rendering standard slip rings incapable of accommodating such high-density circuitry.

Should one simply switch to a larger slip ring? This is not a viable solution, as doing so would interfere with other internal components of the turntable. What about using two slip rings in parallel? Aside from making the wiring extremely complex, this approach would also compromise the overall reliability of the system. So, how exactly can one break this impasse?

JINPAT answer is an " nesting doll-style" integrated through-hole slip ring. Its core design concept is remarkably ingenious: it cleverly utilizes the residual space within a standard through-hole slip ring to embed and integrate a smaller electrical slip ring inside. Essentially, this amounts to "hiding" one slip ring inside another, thereby doubling the number of available circuit channels while keeping the outer diameter virtually unchanged.

Thanks to this innovative design, you can consolidate power circuits, encoder signal lines, multiple control signal channels, and even a complete Gigabit Ethernet channel—all within a single, compact slip ring unit. Even more impressively, actual test results demonstrate that the Bit Error Rate (BER) for Gigabit Ethernet signals transmitted through this slip ring consistently remains below 10⁻⁹. This means that for every billion bits of data transmitted, fewer than one error occurs—a performance metric that fully meets the rigorous demands of industrial real-time communication and video transmission applications.

For equipment such as Inertial Measurement Unit (IMU) calibration turntables, radar test platforms, and automated inspection rotary stages, JINPAT integrated design offers significant advantages: it not only conserves valuable internal space but also greatly simplifies internal cable routing. Thanks to a single coaxial hollow shaft running through the entire unit, all power, data, and signal connections can be handled with ease.
