Mod-Tronic Instruments Ltd. can supply a variety of thermocouple connectors. Our selection includes Mercotac rotary connectors which are superior to conventional slip rings in many ways. Some of the benefits include durability, compact size, and low cost. They also offer less than one milliohm resistance and extremely low electrical noise. The revolutionary design of these connectors uses liquid metal to avoid wear, resulting in a maintenance-free solution. As opposed to slip rings that typically last several for million revolutions, Mercotac rotary connectors can last over a billion revolutions in many applications.
Mercotac rotary electrical connectors offer an exceptionally low resistance electrical connection. The conduction path uses a liquid metal that is molecularly bonded to the contacts. As a result, the connection stays constant and unchanging for the entire life of the connector. In contrast, brush slip rings use a graphite or metal brush that rubs against a rotating metal ring to transfer the signal or current. This type of design leads to problems including wear, oxidation, high electrical resistance, and resistance fluctuations that cause electrical noise.
A variety of rotary electrical connectors are available, ranging from one conductor to eight conductor types. Visit our website for detailed specification on the various models.
