Disc Slip Ring

Disc Slip Ring is a precision device used to solve power, signal, and data transmission problems in rotating systems. Its core function is to establish a reliable and uninterrupted electrical connection between fixed and rotating components, ensuring stable transmission of current, signals, or data during equipment rotation. Disc Slip Rings, with their unique flat design, demonstrate significant advantages in applications with limited space or strict height requirements.

Highly integrated and compact design

Features: The disc slip ring adopts a flattened structure, with a height usually lower than 50% of traditional column Slip Rings, a diameter range covering 10mm to 500mm, and a thickness as low as 5mm.

Data: Taking a certain model of micro disc slip ring as an example, its diameter is 38mm, thickness is only 8mm, weight is less than 100g, but it can carry 12 signals and 6 power channels, with a rated current of 5A/channel and a signal transmission rate of up to 1Gbps.

Advantages: Significantly saves vertical space and is suitable for highly sensitive equipment such as drone pods and medical CT scanners.

Low friction and long lifespan

Features: Using precious metal (gold/silver alloy) or composite material contact brushes, combined with precision machining technology, to achieve stable contact resistance and extremely low wear rate.

Data: The model slip ring has a contact resistance fluctuation range of ≤ 5m Ω under rated load, and a service life of over 500 million revolutions per minute (calculated at 60rpm, approximately 9 years of continuous operation).

Advantages: Reduce maintenance requirements, lower downtime costs, especially suitable for long-term operating equipment such as wind turbines and industrial robots.

High speed rotational stability

Features: Optimized dynamic balance design and bearing system, supporting stable transmission under high-speed rotating conditions.

Data: A certain high-speed slip ring model can reach a speed of 5000rpm, with a signal attenuation rate of<0.5db>

Advantages: Meet the requirements of applications such as radar antennas and high-speed cameras that require rapid rotation.

Mixed signal and power transmission

Features: Integrated power supply and signal channel, supporting synchronous transmission of analog signals (such as 4-20mA), digital signals (such as RS485, CAN bus), and high-frequency signals (such as HDMI, USB 3.0).

Data: The model slip ring can simultaneously transmit 12 analog signals (accuracy ± 0.1%), 4 Gigabit Ethernet signals (bit error rate<10>

Advantages: Simplify system design, reduce wiring complexity, and improve equipment reliability.

Environmental adaptability

Features: Adopting a sealed structure and protective coating, it has the ability to prevent dust, water, and corrosion. Some models support working temperatures from -40 ℃ to+85 ℃.

Data: A certain industrial grade slip ring has passed IP67 protection level certification, with no corrosion after salt spray test for ≥ 96 hours, and vibration test (MIL-STD-810G) passed 10g@10-2000Hz .

Advantages: Suitable for harsh environments such as marine engineering and food processing.
