Model 215-2K
Brushless Slip Ring
Two Conductor,
Amps: 2@15
Volts: 2000
The Mercotac® model 215-2K brushless slip rings are an ideal choice for oil well wirelines due to their clean and consistent signal transmission and extended lifespan. They can also be used anywhere a two-channel device with very high voltage rating is needed, such as in ultrasonic applications. Their compact size also makes them ideal replacements for brush-type slip rings.

Model 215-2K Suggested Mounting Methods
Model 215-2K is typically mounted by either the black body or the white plastic bushing on either end using a set screw or split clamp. When used horizontally, mount the Mercotac so the body of the connector rotates.
Body Mount
Bushing Mount
Horizonal Mount to Body
Good mounting method. (but vertical orientation is better)
Adaptor Mount to Body
Use when the shaft diameter is smaller than the body of the Mercotac.
Horizonal Mount to Bushing
Used if the shaft cannot be fitted to the body diameter.
Thermal Insulated Mount to Bushing
May be needed if thermal insulation is necessary. Used if the shaft cannot be fitted to the body diameter.
Top Mount to Body
Best mounting method.
Bottom Mount to Bushing
Floating Torque Arm Mount to Body
Protective Housing Mount to Body
Recommended for wash-down or dirty environments. Also recommended for food processing applications.
Vibration Isolation Mount to Body
With flexible bellows.
Vibration Isolating Mount to Body
With floating drive coupling.
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.
