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

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.

The low-cost and compact Mercotac Model 430 slip ring is a versatile solution that can be used in various industries, including packaging, medical equipment, and robotics. In the packaging industry, it can ensure consistent and high-quality sealing of plastic bags and food containers because it allows connections for both the sensitive thermocouple signals and power to the heating elements. Additionally, the slip ring's multiple contacts are ideal for robotics applications where both sensors and actuators need connections. Its reliable performance, ease of installation, and cost-effectiveness make the Model 430 an excellent choice for slip ring applications that require both power and signal connections.
