25.4mm Hole Dia Pancake Slip Ring Ultra Low Resistance , Professional Solution
Description of P025 PCB Pancake Slip Ring
P025 series PCB slip ring has an inner diameter of 25.4mm and a thickness of 6mm (the thinnest can reach 5mm). The P025 series innovatively uses PCB substrate, ultra-hard gold plating treatment, and ultra-thick copper foil technology to support the mixed transmission of current and signal. It has the characteristics of high stability, low torque, low loss, maintenance-free, low electrical noise, and ultra-long lifespan.
Features of P025 PCB Pancake Slip Ring
1. Hole size:25.4,thickness:6mm;
2. Support 0~12 circuits power/signal;
3. Adopting fiber brush technology make sure reliable contact under very low friction ;
4. Low contact resistance, no friction debris;
5. Can be combined to transmit precision signal and supply power;
6. Precious metal brush ensure high stability and reliability.

When you have a height restriction, a "pancake" slip rings - also called a "flat" or "platter" ring - could be the best solution. These slip ring units are based on a disc-shaped rotor, which is embedded with concentric grooves to carry the signal and power, with a brush block assembly mounted over the top to act as the stator. We can customize this type of slip ring from 4 to 50 channels, in any center bore size. Contacts use precious metals and operating speed depends on the number of channels and overall size of the slip ring.
