Gallium Alloy Liauid Metal Rotary Through Bore Multi Connectors(10.2mm)
Introduction
The rotating electrical connectors are using the special insulation, sealing, and conductive technologies. The out case
material is the aluminumalloy or stainless steel. They are used for any kind of rotating objects of signals like micro voltage, current,
EMF, thermo couple, strain gauge, aduio,video, high frequency etc. and electric power connections. All types of our liquid metal
rotary connectors support CE RoHS compliance. Please contact us for detail.
Characteristic
Very low electric noise Very low cost Very low cost Suitable for signal and power transfer of rotating devices or instruments
No maintenance and better reliability than traditional slig rings Very low contact resistance (Less than 1mΩ)
Application
Index table for signal and power connection Resistor cutting machine Electro plating line Rotary stage Cable wheel
Circle knitting machine Coloring device Robots Rotary lamp box Surgical lampReel to reel plating line equipment
Speed dome camera Package machine Heating roller Laminating machine Winding machine Spinning LED sign board

●The minimum temperature for liquid metal 46L
●Solid temp is : +7.6℃
●There is a "super cool" effect, when a slip ring contain liquid metal 46L put in the room temp. 0℃, the liquid metal will not be solid
immediately, there will have a 2--4 days range the liquid metal 46L will keep in liquid status, just like the river water still run in the
0℃
●The liquid metal slip rings are recommended to be used within 3 months after shipping. If the slip ring has rotation not smooth
condition after 3 months storage in the room temp. undertemp. +8℃. Please put it in the warm room (over 50℃) to recover the
liquid metal status.
●The liquid metal is not so sticky like mercury which can be sticky(touched) on the silver plated conductor surface. The liquid metal
slip rings' vibration resistance ability is much less than mercury types. Any light vibration, impact,shock will make the liquid metal to
move out from the main conductor chamber to another conductor's room. That will make short circuit easily.
