Details

ByTune through hole slip ring---BTH0318 are one-piece conductive slip rings with a hole in the center, also known as hollow slip rings. These slip rings can be designed to adapt to various hole diameters and are mainly used to transmit precision signals, large currents, and high voltage working environments. They have the characteristics of low torque, low loss, and low electrical noise, which can stably transmit power or signals, cool or air media, optical or RF channels, etc.

 

Features

 

Customization

We can customize the number of electrical channels of through-hole slip rings based on application requirements. Through-hole slip rings can also be made with specific materials to meet unique environmental or operating requirements, such as high temperature or corrosive environments.

Compact size

The compact size of BTH0318 through-hole slip rings is suitable for a variety of application scenarios. For example, in the field of aerospace, the equipment on the aircraft has strict restrictions on space and weight. The compact size of through-hole slip rings can meet these requirements and provide reliable signal and energy transmission for rotating parts on the aircraft. At the same time, in some narrow industrial production sites, such as detection equipment inside pipelines, compact through-hole slip rings can also play an important role.

Through hole design

The through hole is usually located in the center of the slip ring, so that when the rotating shaft passes through the through hole, the force on the slip ring is more uniform, reducing wear and failure caused by uneven force. At the same time, the through hole in the center also facilitates the installation and connection of the slip ring with other equipment components, ensuring stable transmission of signals and energy.

FAQ

 

Q: What are through bore slip rings used for?

A: Through bore slip rings are used in applications that require bore space for other capabilities, such as a rotating shaft, cooling, air media, optical or RF channels, and more. The slip ring can be designed to fit a variety of bore sizes.

Q: Is it possible to restore slip rings at the end of their service life?

A: Whether or not restoration is advisable must be decided in each individual case depending on the design and the condition of the slip ring. Restoration or rework may well be possible in certain circumstances.

Q: What is the default temperature range for slip ring transmitters?

A: The temperature resistance of the weakest component determines the temperature range of a slip ring. The large number of customer-specific slip rings complicates the definition of a default temperature range. Our operating temperature range -40°C … +100°C can be taken as a rough guide.

Q: Where can I find information on the configuration (colour codes) of individual wires?

A: You can find detailed information on the configuration and a description of the electrical connections of the rotor and stator in the data sheet. Please don't hesitate to contact us if you require another copy of a data sheet. We'll be happy to help.

Q: What's your warranty?

A: For standard models,free replacement with 6 months, free repairment within 1 year.
