MOUNTING
End-of-Shaft
This series of rotating electrical connectors is intended to be mounted at the end of a workpiece and is typically secured via set screws to the shaft, or has a variety of other options available.
RPM
2,000
The maximum rotational speed of a ROTOCON rotating electrical connector is directly limited to the temperature the slip ring reaches under maximum current load and rotational speed within a given environment. The speeds shown are up to and not guaranteed in absolute maximums.
TEMPERATURE
-35˚F to 160˚F
(-20°C - 70°C)
Temperature rating is measured at the body of the ROTOCON slip ring under maximum current load and rotational speed; it should not exceed 160˚F for continuous periods of time. For application specific scenarios, please contact Meridian Laboratory.
CONTACT RESISTANCE
0.2mΩ
Contact resistance refers to the electrical resistance between the stationary and rotating portions, internal to the ROTOCON rotating electrical connector. This is measured without additional cabling or connectors, and is internal to the units themselves. This is measured stationary or rotating, regardless of rotational direction, speed, or orientation.

For through-hole slip rings, check out our MXT-Series of through-hole rotary electrical connectors.
The standard MX-2-6 is mounted by the shaft at the end of a rotating device and secured via a set screw on a flat on the shaft. Shaft drivers are available for larger diameter mounting holes upon request.
Shaft flanges can be attached to the MX-2-6 shaft to mount the slip ring to your workpiece. Standard and customized flange offerings are available.
Body flanges can be attached to the MX-2-6 body to mount the slip ring to your workpiece. Customized flange offerings are available.
Double end of shaft options exist to transmit low value torque through the MX-2-6 slip ring. This allows for devices such as encoders, resolvers, motors, and other instruments to be attached to the slip ring’s shaft.
FAQs
Common Rotating Electrical Connector Questions
How good is the signal quality of a ROTOCON slip ring?
The signal quality of ROTOCON brushless rotary electrical connectors is unmatched when compared to conventional brushed slip rings. In laboratory testing, measured channel resistance of rotating multi-channel ROTOCONs was found to vary less 0.2mΩ (zero point two milli-ohm) on average; orders of magnitude lower than that of conventional brushed slip rings. This stable resistance and low impedance allow ROTOCONS to be modeled as simple wires/cables in electrical systems designs. For more information, see our ROTOCON Advantages page for demonstration videos and white papers related to slip ring signal quality.
Can a ROTOCON pass Profinet, Ether-CAT, Ethernet, and other industrial communication protocols?
Yes, ROTOCON rotary electrical connectors and slip rings are capable of transferring many signal types and communication protocols, including Etherlink, Profinet, EtherNet/IP, Profibus, Modbus TCP/IP, Powerlink, CC-Link IE, SERCOS III, SynqNet, MECHATROLINK-III, ControlNet, RS485, RS432, RS422, EtherCAT, and more generally speaking – any 1000BASE-T Ethernet-based or similar communication protocols. If you have a specific protocol not listed, please contact us directly to determine if your signal is compatible.
What kind of electrical terminations are available?
Meridian Laboratory offers various electrical termination types to meet the requirements of different applications. For most multi-channel models, we offer flying leads, ring terminals, or connectors to terminate to. For application-specific connections, please contact us to discuss how we can best fit your needs.
Can a single ROTOCON be used to transmit both power and signal?
Yes, ROTOCON rotary electrical connectors are extremely capable and successful at transmitting both power and signal within the same assembly, minimizing interference or crosstalk.
Are thermocouples compatible with a ROTOCON?
Yes, thermocouples are fully compatible with Meridian Laboratory’s ROTOCON brushless slip rings. Our ROTOCON technology is engineered to accept virtually any thermocouple type and we can integrate thermocouple wires directly into the assembly. This design attribute minimizes the number of different materials and cold junctions present, ensuring more consistent and reliable temperature measurements.
Does Meridian Laboratory offer miniature ROTOCONs?
The smallest series of multi-channel ROTOCON rotary electrical connectors which Meridian Laboratory offers is the MM Series. For help integrating ROTOCONs into small areas, please contact us for direct support.
