Matoll are the sole exclusive distributor of MERCOTAC® Rotary Electrical Connectors in the UK & EU.  Matoll hold a large quantity of MERCOTAC® stock in both the UK and Germany, ready for next day delivery. 

MERCOTAC® Rotary Electrical Connectors operate on a superior principle. They provide an exceptionally low-resistance electrical connection because it relies on a liquid metal path that’s molecularly bonded to the contacts. The MERCOTAC® connection remains constant throughout the life of the rotary electrical connector.

In contrast, brush slip rings consist of a rotating metal ring upon which a graphite or metal brush rubs to transfer electrical signals or current. Although brush slip rings are operationally simple, this rubbing interface introduces a range of problems, including wear, high electrical resistance, oxidation, and resistance fluctuations, which result in electrical noise.  MERCOTAC® Rotary Electrical Connectors eliminate all of these performance issues.

MERCOTAC®  brushless slip rings use a unique design principle unlike the sliding, brush contact of a slip ring. The connection is made through a pool of liquid metal molecularly bonded to the contact, which provides a low-resistance, stable connection. During rotation the fluid maintains the electrical connection between the contacts without any wear.

  • Unlike most slip rings, MERCOTAC®  products produce near zero electrical noise due to their unique design.

  • Resistance through the MERCOTAC® rotating contact is less than one milliohm, which is much lower than the resistance of a standard slip ring.

  • MERCOTAC®  products do not degrade the signal over time, which does happen with most standard slip rings.

  • MERCOTAC®  products are maintenance free.

  • MERCOTAC®  products are more compact and cost far less than slip rings of equal capacity.

  • Both current power and instrumentation signals can be sent through a single, compact MERCOTAC®  brushless slip ring.
