Pancake Slip Ring
What Makes ByTune's Pancake Slip Rings Special?
The pancake slip ring, also known as a platter slip ring or flat slip ring, features an ultra-thin design. Its low axial height makes it ideal for installation in systems where vertical space is limited but horizontal space is less constrained.
● Height as Low as 5mm
With a minimum axial height as thin as 5mm, the pancake slip ring is suitable for compact spaces like drone gimbals or robotic arms. Ultra-flat housing-free PCB slip rings are available.
● High-Density Channels
It supports 1-24+ circuits in a single unit, enabling simultaneous power/signal transmission (e.g., Ethernet, USB, RS, CANBUS, Decive net, CC-link, FireWire, servo motor signals, etc.).
● Smoother Rotation
The slip ring uses gold-to-gold contacts with <7 mΩ contact resistance, can steadily rotate at 0–300 RPM (higher speeds available for customized designs).
● Lower Electrical Noise
It adopts integrated shielding to reduce electromagnetic interference (EMI), keeping high signal integrity for sensitive applications like medical imaging.
● Customizable Solutions
1. Tailored to your voltage, current, and interface requirements.
2. Circuits: Standard 1-24 circuits (higher on request)
3. Torque: ≤9.25g·m
4. Rotation speed: 0-300 rpm
5. Contact material: Silver-Silver, Gold-Gold
6. Casing material: Aluminum alloy or stainless steel
7. IP Grade: Up to IP68
8. Working temperature: -40℃-+80℃
Common Types Of Pancake Slip Rings

Integrated Pancake Slip Ring
Its conductive channels are manufactured on the entire ring body. It is relatively thin and suitable for equipment with limited space, like small motors and precision instruments. It's overall structure makes it more stable in use, resist vibration and impact.
PCB Separate Pancake Slip Ring
The slip ring is composed of multiple layers of PCB boards, and each layer is connected by vias. It forms a conductive channel by printing conductive lines on the PCB board. And add a thick annular copper or gold plating layer on the board surface to integrate various circuit components.

-
What payment methods do you accept?We accept Wire Transfer (Bank Transfer) and PayPal for secure and convenient transactions.
-
What is your delivery time?It usually takes 1 week for samples of standard models, and 2-4 weeks for bulk production(Custom designs may be longer).
-
So, how do you transport the goods?We ship our slip rings globally via air freight (Door-to-Door Delivery). The estimated transit time is 3-5 working days (varies by destination).
-
What is your warranty policy?All slip rings come with a 3-month free replacement warranty (covers manufacturing defects, excluding misuse damage).
-
What types of signals can the pancake slip ring transmit?In addition to transmitting power and control signals, these slip ring is also suitable for high-frequency signals, RF signals (frequency range up to GHz level). It is also compatible with most existing signal protocols of most devices (such as RS-232, RS-485, Ethernet, USB, etc.).
-
How do you ensure stable signal transmission?Our pancake slip rings use precious metal brush materials and gold-plated and silver-plated copper conductive rings to improve contact stability. We also use a multi-channel design for them and add filtering circuits to the circuit design to reduce high-frequency interference signals in complex environments.
-
How much attenuation do they have?The degree of signal attenuation varies depending on the signal frequency and transmission distance. For low-frequency signals (such as less than 1kHz), these slip rings have almost negligible attenuation at regular transmission distances (such as within 10 meters). For high-frequency signals (such as above 100MHz), the attenuation may be around 0.1dB per meter of transmission distance.
-
Are these slip rings customizable?Yes, we supply the pancake slip ring connectors with customized specifications for you. These include, for example, special numbers of channels, signal combinations, dimensions or higher protection classes. However, delivery times may be longer than for standard products.
