Brushless Slip Ring Model 215-2K

Conductors: 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.

Advantages:

Durable, compact, and low cost
Use for signal and/or power connections
Easy to install and replace
IP 51 protection rating with boot kit
Lightweight with robust metal construction
Long-lasting, energy efficient, and no maintenance
Made in the USA

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 .

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.

Mercotac customers report that by using the brushless slip rings they were able to downsize the unit compared to the older brush style. The brush style becomes very noisy after many runs in and out of the oil wells.

The most important aspect of the brushless style of slip rings is the signal transfer. The signal transfer is very clean and doesn't degrade which is important with today's down hole components. Our Mercotac connection is constant and it is noted for a reliable signal. With the digital tools and down hole communication it is very critical that the signals remain clean; this is accomplished by using the Mercotac product. They are also suitable for ultrasonic applications due to the high voltage capability.

The bearings used in the Mercotac assembly create a smooth operation of the unit. It also gives it an extended life span.
