Learn More about Mercury Slip Rings

What is a mercury slip ring?

Mercury slip rings, like electrical slip rings, are high performance, low contact resistant, and, strong, stable slip rings, which can transfer current and signal.

Mercury slip ring assembly are used for any and all kinds of rotating interfaces. Built with lasting stability, our mercury rotary slip rings are more durable and stronger than brush slip rings. 

In addition, the incorporation of an aluminium alloy in the design and construction of our mercury slip ring connector is the secret behind its special insulating, sealing, and, conducting technology. 

Furthermore, mercury wetted slip rings can work perfectly in combination with micro voltage, current, EMF, thermos couple, strain gauge, high frequency and electric power connections.

Why do you choose our mercury slip rings?

You can choose non mercury, mercury wetted, high power mercury slip rings.
