This high speed standard through hole slip ring is engineered to handle extreme rotational speeds of up to 10,000 RPM. It has up to 64 channels, with each channel carrying a current of 30A. So it can also transmit a large number of different signals and data at the same time to the devices. These make it widely used in precision applications such as blood analyzers, centrifuges, and high-performance agricultural machinery.

Features

Low resistance

It havs conductive parts made of precious metals such as copper, silver, and gold. These materials have excellent conductivity and low resistance, which can reduce losses and attenuation when transmitting current and signals.

Wide temperature range

The high speed standard through hole slip ring works normally in a wide temperature range, such as -40°C~+100°C. It is also suitable for industrial steelmaking equipment or extreme low temperature environments in space.

Customizable

In addition to providing standardized through-hole slip rings, we also customize its size, number of channels, transmission parameters, installation methods and other parameters according to your needs.

FAQ

Q: How to ensure the signal transmission quality of through-hole slip rings?

A: This involves a lot. For example, we upgrade better conductive materials such as gold and silver to make its contacts to reduce resistance fluctuations. We also design its internal structure with more circuit channels and isolate each channel to reduce interference between signals.

Q: How to choose a slip ring according to the power requirements of the equipment?

A: Before choosing, we need to consider factors such as the maximum lifting weight, lifting speed, and rotation speed of your equipment. This can help you calculate the required power and then choose a slip ring that can carry the corresponding current. The most important point is that the rated current of the slip ring must be greater than the maximum current required when the crane is working normally.
