9-Channel Ultra-Thin PCB Slip Ring With1A Current And 25V Voltage For Micro-Robots And Medical Equipment

This product is an ultra-slim, 9-channel PCB-style electrical slip ring designed specifically for space-constrained applications. Featuring gold-on-gold contact technology and a PCB-based housing, it integrates nine independent channels—each supporting a 1A current—within an extremely compact profile. It operates at 24V with a maximum rotational speed of 200 rpm and comes equipped with nine AWG26 Teflon-insulated leads (300mm in length). This slip ring offers a highly reliable connectivity solution for rotating electrical equipment—such as precision instruments, microrobots, and medical devices—that demands strict adherence to space limitations and signal integrity.

High-density 9-channel integration on an ultra-thin PCB structure: Features a PCB-based housing design that is lightweight and compact, integrating nine independent channels within a limited footprint to significantly save internal installation space.
Gold-on-gold contact materials ensure signal purity: Core contacts utilize a gold-on-gold alloy, offering extremely low contact resistance and excellent oxidation resistance; with dynamic resistance <0.01Ω, it ensures stable, lossless transmission of low-level signals and currents during rotation.
Wide operating temperature range: Supports temperatures from -30°C to +100°C, making it suitable for diverse applications ranging from low-temperature environments to high-temperature operating conditions.
High insulation resistance ensures electrical safety: Insulation resistance is ≥1000MΩ/100VDC, with minimal leakage current between channels and between channels and the housing, ensuring safety during the simultaneous transmission of high voltage and signals.
AWG26 Teflon cable configuration: Equipped with nine AWG26 Teflon wires (300mm length) that offer high-temperature resistance, corrosion resistance, and low signal loss, ensuring reliable long-term connectivity.
Stable dynamic performance at 200 rpm: Achieves smooth operation at 200 rpm within a compact structure, meeting the dual requirements for rotational speed and signal stability in precision equipment.

Ultra-compact rotary connection for space-constrained equipment
The core innovation of this product lies in its PCB-style housing structure. Unlike traditional cylindrical slip rings, its ultra-thin profile allows for direct integration into PCBs or equipment interlayers, significantly saving both axial and radial space. It is particularly well-suited for applications with strict size constraints, such as miniature robotic joints, portable medical devices, and precision optical instruments.
Gold-on-gold contacts ensure zero signal distortion
The combination of gold-on-gold contact materials and dynamic resistance of <0.01Ω ensures:
Extremely low and stable contact resistance, minimizing signal attenuation and voltage drop
Excellent oxidation and sulfidation resistance, suitable for humid and high-temperature environments
High fidelity for low-level signals, ideal for precision signal transmission in sensors, encoders, etc.
Long service life and wear resistance, reducing maintenance frequency
High insulation resistance enhances system safety
Insulation resistance of ≥1000MΩ/100VDC means:
Extremely low leakage current (microampere level) between channels and between channels and the housing
Strong anti-interference capability, suitable for mixed signal and power transmission
Resistance to moisture and contamination, adapting to complex operating environments
Wide temperature range suits diverse application scenarios
An operating temperature range of -30°C to +100°C makes it capable of handling:
