Model 110

Brushless Slip Ring

One Conductor,
10 Amp

Model 104

Brushless Slip Ring

One Conductor,
4 Amp

The Mercotac® model 110 brushless slip ring is designed for up to 10A
applications where a single channel is needed. The Mercotac model 104 while
having a lower current rating is designed for higher RPM applications. These
models are intended to be mounted at the bottom of a vertical rotating shaft
or wherever a threaded stud mount or connection is required. Commonly
used in plating, grounding, and static charge applications they are also
suitable for microelectronics, moisture sensing, wire metal fatigue testing,
and more.

Model 110 & 104 Connections

Model 110 & 104 Standard Wire Connections

Ring terminal for stationary wire attachment. Metal receptacle press fits onto rotating member of machine
Ring terminal for stationary wire attachment. The Mercotac unit plugs into the receptacle after the receptacle is press fit into the rotating member of the machine.
Note: The metal receptacle used for mounting is electrically conductive. Therefore, if desired, it can be used as the electrical connection between the 110 and the rotating member of the machine using Part #5920. However, if an insulated mounting at the rotating member is being used, then Part #5921-S with six inch wire lead is used for the electrical connection.

Model 110 & 104 Suggested Mounting Methods

Model 110 is typically mounted by the knurled metal receptacle, which is press-fit into the rotating member of the machine. When mounting horizontally, use the similar model 110-T instead to be able to mount the Mercotac rotary connector so that the body of the connector rotates.

Bottom Mount with Conductive Shaft


Preferred mounting orientation.

Vertical Mount with Electrically
Insulated Shaft

The Mercotac body is electrically hot.
An electrically insulated shaft can isolate it, if needed.

Horizontal Mount with Electrically Insulated Shaft

The Mercotac body is electrically hot. An electrically insulated shaft can isolate it, if needed.

Thermal & Electrically Insulated Horizontal Mount

Use if electrical and thermal insulation is needed

Vibration Isolating Mount

Protective Housing Mount with Conductive Shaft

Installation Notes:

  • The up arrow should not point below horizontal
  • Do not solder to or bend connector tabs
  • Avoid lateral forces and mechanical loads (overly stiff or tight wires)
  • Do not rigid mount both ends of connector
  • Limit mounting eccentricity (runout / wobble) to .005″ (.13mm)
  • Provide overload protection within the circuit
  • Avoid vibration and bumping motions
