Meridian laboratory rotary ground/contact
Slightly used (installed on prototype rotary welders, not production)
This is model MC-500 with specs described below, which are highlighted in red and correspond to picture 2.
These contacts/grounds are $2,300 off the shelf.
ROTOCON Model MC high current rotary contacts are an innovative new concept. Unlike conventional slip ring contacts, the MC uses Meridian Laboratory's proprietary sealed design. Arcing, "make and break" electrical contact, friction, and the resulting short operating life are all eliminated by using the MC. Welding, plating, and other high current applications benefit with longer product life and substantially reduced energy consumption. A typical slip ring contact can lose 40% of its electrical efficiency due to unavoidable wear - while the MC continues working with greater than 95% efficiency! The MC's energy savings alone make it an excellent investment. The MC can operate continuously at the rated maximum current without auxiliary cooling and is designed to handle 100% current overloads (with some heat generation). The surprisingly small size of the MC Series makes installation quick and easy. Tight seals and a corrosion proof housing provide a long service life with zero maintenance.
* Continuous Duty Cycle Operation
* Mount In Any End Of Shaft Orientation
Mounting: Any end-of-shaft orientation is acceptable. One end of the MC must have a flexible link to the equipment. Rigid connection of both ends should be avoided.
Housing: Corrosion resistant stainless steel.
General: Permanently lubricated bearings at both ends.
Voltage: Any voltage is acceptable with single contact MC.
Stationary Contact Resistance: One milliohm.
Rotating Contact Resistance: Same as stationary resistance, no change with RPM.
Ambient Temperature: Not to exceed 160 F (70 C), assuming minimal heat flow through shaft and housing mounts. If machinery surfaces are hot, use insulated mounting systems.
