Model 1500
Brushless Slip Ring
One Conductor,
500 Amp
The Mercotac® model 1500 series brushless slip rings are specifically designed to meet the demands of high-power applications, making them the ideal choice for plating electrodes and welding cable reels. These slip rings feature a durable stainless steel housing as a standard feature, providing enhanced protection and durability in demanding environments.

- “SS” designator indicates stainless steel ball bearing (recommended for wet or corrosive environments)
- “-1” designator indicates an external dust seal
- Note: The 1500 series Mercotac™ Connector comes standard with a stainless steel body, which is electrically “hot” to the internal conductor at higher voltages
Model 1500 Accessories
There are no accessories currently for this model, however, if an external dust seal with an IP51 protection rating is needed, select the Model 1500-1.
Model 1500-1 or 1500-1-SS Brushless Slip Ring
Includes an external dust seal
IP 51 protection rating
All other features are the same as for the standard 1500 Model.
Safety Note: The stainless steel housing of the 1500 series Mercotac connector at higher voltages is electrically “hot” to the internal conductor.

Model 1500 Suggested Mounting Methods
Model 1500 Standard Wire Connections
Model 1500 is typically mounted by the threaded stud on either end or by the steel body using a set screw. When mounting horizontally, mount the Mercotac so the body of the connector rotates
Top mount with conductive shaft
Bottom mount with conductive shaft
Horizonal Mount with conductive shaft
Installation Notes:
- The up arrow should not point below horizontal.
- Do not solder to or bend terminals.
- Avoid lateral forces and mechanical loads (overly stiff or tight wires).
- Do not rigid mount both ends of the Mercotac.
- Limit the mounting eccentricity (runout / wobble) to .005″ (.13mm).
- Provide overload protection within the circuit.
- Avoid vibration and bumping motions.
