Notes on this data
Mercury-wetted (liquid metal) contacts: Mercotac states the connectors contain a small amount of elemental mercury and cannot be said to conform to RoHS; EU users must check exemptions and national rules. Speed and temperature for this model not read.

Mercotac Model 215-2K replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original Mercotac part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
Typical applications
What a slip ring is
This group covers slip rings that do not fit a single standard format, including modular and split designs, contactless capacitive or optical data rings, temperature-rated units, quick-connect terminal designs, very high circuit counts and application-specific assemblies for wind turbines or packaging. All solve the same problem: transferring power, signals or data between stationary and rotating parts of a machine. What differs is the construction, which may be a split housing, a modular stack, a non-contact data path or a special material set.
When engineers choose a slip ring
Engineers look at these designs when a standard capsule, through-bore or pancake unit does not fit the job. Split rings suit retrofits onto existing shafts. Contactless data rings suit high data rates or long life without wear. Modular units allow circuit counts to change between machine variants. The trade-offs are cost, availability and, for custom designs, longer lead times and qualification. Match the construction to the real constraint, whether that is installation, data, temperature or circuit count.
How to specify the Mercotac Model 215-2K
Send these with your enquiry and an engineer can confirm the right Model 215-2K variant or an equivalent:
- What makes the application non-standard: installation, data, temperature, circuit count or format
- Circuits, current and voltage (A, V)
- Data protocols and rates
- Speed (rpm) and expected life (revolutions)
- Bore, envelope and mounting (mm)
- Temperature range (°C) and IP code
- Terminations, such as flying leads, connectors or quick-connect tabs
Common mistakes to avoid
- Choosing a special design when a standard type with minor changes would do
- Not stating the actual constraint, so the supplier offers the wrong format
- Assuming contactless data channels also carry power
- Underestimating lead time for custom or modular builds
Mercotac Model 215-2K: frequently asked questions
Can you help replace Mercotac Model 215-2K or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including Motion Control Products options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Mercotac Model 215-2K?
Two-conductor liquid-metal rotating connector rated 15 A at 2,000 V, the high-voltage option in the two-conductor range. Published series figures include circuits 2, current per circuit 15 A, voltage 2,000 V. It is made by Mercotac, Inc.; Specify Motion can help source it or propose an equivalent.
Who makes the Mercotac Model 215-2K?
The Mercotac Model 215-2K is made by Mercotac (Mercotac, Inc.) and is listed here for engineers comparing options. Specify Motion is not affiliated with Mercotac, Inc.; brand names are used only to identify the product.
What is the circuits of the Mercotac Model 215-2K?
The published series maximum circuits is 2. Individual models and sizes in the Model 215-2K range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the Mercotac Model 215-2K?
We can assess suitable replacement options. On published figures, Motion Control Products HR Series Faston Type Slip Ring is options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
What is a split slip ring?
A split slip ring has a rotor and housing made in two halves, so it can be fitted around an existing shaft without removing the shaft or its bearings. It suits retrofits and large machines where disassembly would be costly. Expect tighter installation tolerances and possibly a lower speed rating than a one-piece unit.
What is a contactless slip ring?
A contactless slip ring transfers data, and sometimes power, across rotation without sliding contacts, using capacitive, inductive or optical coupling. There is no wear on the data path, so life is long and very high data rates are possible. Contactless power is usually limited, so many designs combine a contactless data channel with conventional power rings.
