Model 430
Brushless Slip Ring
Four Conductor
Amps: 2@4A and 2@30A
Volts: 250
The Mercotac® model 430 is ideal for heated roller applications that need both a connection to sensitive thermocouple signals and for powering the heating elements. It’s also a great choice for compact, low-cost, and reliable slip rings that can handle both signal and power connections in robotics, medical equipment, or packaging machinery.

Model 430 Suggested Mounting Methods
Model 430 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
Brushing 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.
