ROTOCON Brushless Slip Rings Solve Dilemmas for Data Equipment Manufacturer
A leading manufacturer of fiber optic cable and copper cable hardware / equipment approached Meridian Laboratory. They needed to address issues with existing brush-style slip rings on its manufacturing equipment. While the conventional slip rings could power programmable logic controllers and other analog devices, the traditional brushed slip rings caused loss of signal and produced noise within the Ethernet (CAT5/CAT5e) signals extreme enough to lose the functionality of the machine. As a result, machine output decreased and the number of defective products increased.
After extensive slip ring maintenance and even experimenting with both standard and custom wireless solutions, the manufacturer still could not solve the problem. Ultimately, they quit using the machine entirely due to the following issues:
- Signal noise made functionalities of the machine unusable.
- Existing slip rings required routine maintenance and adjustments.
- Wireless solutions were not providing data at the speeds required.
Soon after consulting Meridian Laboratory, this customer learned of the ROTOCON® slip ring alternative. Designed and manufactured by Meridian Laboratory, ROTOCON brushless slip rings have a long history of improving all types of applications requiring exceptionally low noise, including thermocouple, strain gage, video, audio, Ethernet and other signal level uses. Working with the customer, Meridian Laboratory engineers designed ROTOCON MX high-performance rotary electrical connectors that were customized to meet both the power and signal level needs for many years to come. The ROTOCON provided a 100% maintenance-free solution which restored the machine’s usability and eliminated all prior issues the company faced with conventional slip rings.
- ROTOCON allowed power and signal to work together simultaneously within the same assembly.
- 100% maintenance-free alternative without needing adjustments or upkeep.
- Allowed machine to exceed its original performance/build specifications and decrease product defects.
This video shows the change in resistance of two slip rings while rotating. On the left side, the ROTOCON’s resistance stays extremely low and stable, while the conventional brushed slip ring has a varying resistance much greater than that of the ROTOCON. The ROTOCON demonstrates approximately 1/20th of the resistance change when compared to a traditional brushed slip ring during rotation.
