Model 230
Brushless Slip Ring
Two Conductor,
Amps: 30
Volts: 250
The Mercotac® Model 230 brushless slip rings are used in airfield lighted windsocks to allow rotation to indicate wind direction while maintaining electrical connectivity to the lighting system to increase visibility in low light conditions. They are also used in any application that requires up to two 30 Amp channels, such as in laminating machines.

Model 230 Suggested Mounting Methods
Model 205 is typically mounted by either the black body or the contact. Body mount typically uses a set screw or split clamp. Contact mount is held in the installed receptacle by a spring fit. It is best to mount the Mercotac so the body of the connector rotates. When used horizontally, mount the Mercotac so the body of the connector rotates.
Bottom Mount with Conductive Shaft
Preferred mounting orientation.
Top Mount with Conductive Shaft
Use for top rotation.
Horizontal Mount with Electrically Insulated Shaft
The Mercotac body is electrically hot. An electrically insulated shaft can isolate it, if needed.
Thermal & Electrically Insulated Horizontal Mount
Use if electrical and thermal insulation is needed.
Protective Housing Mount with Conductive Shaft
Vibration Isolating Mount
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.
