Model 110-T One Conductor,
10 Amp Model 105 One Conductor, 4 Amp

Mounts at the end of a rotating axis. Mount by the press fit receptacle accessory. Wires attach using the accessory receptacle and cap.
Mercotac models 110-T & 105 are ideal for shaft grounding applications, including HVAC and VFD motor shaft grounding, thus avoiding very costly bearing damage.

Note: The anodized aluminum housing of the 110 & 105series Mercotac is electrically "hot" to the internal conductor.

Model 110-T & 105 Accessories

5920

one contact receptacle

5921-S

one contact receptacle w/ 6" wire

5952

one contact cap
w/solder lug




55337

ring terminal (12-10 AWG)

Receptacle used for mounting to rotating device. Accessories are required for wire connections. Order Separately.

Model 110-T & 105 Connections

Plastic cap with solder lug to attach stationary wire.

Metal receptacle press fits into rotating member 01 machine.

Cap plugs onto stationary end of 110-T for attachment of stationary wire.

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-T & 105 Suggested Mounting Methods

Model 110-T is typically mounted by the knurled metal receptacle, which is press-fit into the rotating member of the machine When mounting horizontally, mount the Mercotac so the body of the connector rotates.

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
