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 High & Low Temperature Slip Ring
Send these with your enquiry and an engineer can confirm the right High & Low Temperature Slip Ring variant:
- 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
High & Low Temperature Slip Ring: frequently asked questions
What is the High & Low Temperature Slip Ring?

Who makes the High & Low Temperature Slip Ring?
The High & Low Temperature Slip Ring is part of a range available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the circuits of the High & Low Temperature Slip Ring?
The published series maximum circuits is 48. Individual models and sizes in the High & Low Temperature Slip Ring 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.
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.
