A mercury slip ring is simply a form of rotary joint fluid medium. It is a work component. It is also known as mercury conductive ring and electrical rotating connector. It is enjoying the performance like electrical slip rings; it provides 360 degrees of power and signal in stator and rotor side with different industry tools. It is a medium fluid as compared to other slip rings. It has created a compact structure. It also has small size characteristics. It has a good advantage with mercury contact as a conductive media. It only transfers signals and current with liquid metal under normal temperature.
The main feature of mercury slip ring is high precious signals, strong stability, and no noise. It has longer life except for slip ring when rotate. It is a very attractive and competitive product. The mercury slip ring is appropriate for a rotating system. Without a complex structure, the rotating part is becoming more reliable maintenance – free. It has no noise, low signal, pass large current, high speed, and low signal distortion. This kind of slip rings has a wide range of applications. Mercury slip ring plays a very important role in a civilian to military industry and traditional industries to new industries. It provides for various application the most economic, scientific and profitable rotary solution of the mercury slip ring. This is too much durable than brush rings. It has a higher rotating speed. It flows a large current. It is supported max up 1500 to the single wire. It is supported 1 to 12 circuits signals or power and it is about 0.1 ma to 1500 ma. It built with sealing material, conductive technology and insolation. Aluminum alloy or stainless steel also used during its production. For transferring signals applied tiny voltage, thermocouple, EMF, video signals, computer signals, strain gauge, and electric power connection.
The Mercury Slip Ring Features
1-It is used sealing material, no maintenance, insolation, conductive technology production, better reliability except traditional slip ring
2-Its housing material is made up of stainless steel and aluminum alloy.
3-It has a resistance that is less than 1m
4-It has an anti-interface
5-It is available in low cost
It is applicable in some situation. The most super conductive experiments used mercury. This kind of slip ring uses to transfer the conductive weak signals like the thermostat box. It is difficult to fix it. Miniature slip ring can be rotated from both sides. Do not weld it directly.

Must notice these things in Mercury Slip Rings
- The storage and vertical mounting should keep the UP in the upper position
- Need to connect a terminal for some times
- The losing connection may cause heating when you apply electricity
- Use the temperature between 60 degree Celsius to 140 degrees Fahrenheit
- Use ambient temperature and self-healing
- The vibration in the slip ring may lower the life
- Don’t try mechanical loads
