Slip Ring Model 104 & Model 110

Conductors: One Conductor
Amps: 4 or 10
RPM: 7500 or 3600

The Mercotac® model 110 brushless slip ring is designed for up to 10A applications where a single channel is needed. The Mercotac model 104 while having a lower current rating is designed for higher RPM applications. These models are intended to be mounted at the bottom of a vertical rotating shaft or wherever a threaded stud mount or connection is required. Commonly used in plating, grounding, and static charge applications they are also suitable for microelectronics, moisture sensing, wire metal fatigue testing, and more.

Advantages:

Durable, compact, and low cost
Use for signal and/or power connections
Easy to install and replace
Lightweight with robust metal construction
Long-lasting, energy efficient, and no maintenance
Made in the USA

Connector options are noted below. They are not included with a 104/110T Mercotac purchase. Order the desired connector(s) separately.

Description: One Contact Receptacle
Item #: 5920

One solder holes for 18 AWG wire
Suitable up to 10 Amps

Description: One Contact Receptacle
Item #: 5921-S

With one pre-attached 6” wire (18 AWG)
Suitable up to 4 Amps

Description: Ring Terminal
Item #: 55337

For 12-10 AWG wires
Suitable up to 10 Amps

Description: One Contact Cap
Item #: 5952

With one solder lug for 18 AWG wire
Suitable up to 4 Amps

Description: A receptacle is used for mounting to the rotating device. The accessories are required for wire connections, since the Mercotac units cannot be soldered to directly. Order Separately.

Models 104 & 110 are typically mounted by either the black body or the top contact. When used horizontally, mount the Mercotac so the body of the connector rotates

Receptable Mount

Bottom Mount with Conductive Shaft

Preferred mounting orientation.

Vertical Mount with Electrically Insulated Shaft

The Mercotac body is electrically hot. An electrically insulated shaft can isolate it, if needed.

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

Vibration Isolating Mount

Protective Housing Mount with Conductive Shaft

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 Mercotac models 104 & 110 brushless slip rings are a durable electrical connection used to transmit power and signals between rotating and stationary parts. The model 110 is designed for up to 10A applications and offers versatility in various industries, while the model 104 with a 4 amp current rating is used in higher rpm applications. Some of the applications include

Electroplating: Used for the connection to rotating electrodes
Grounding: Used for grounding rotating shafts.
Static charge: Used for applying a static charge to rotating devices

In addition to these applications, these slip rings are suitable for microelectronics, chemical plating process control, wire metal fatigue testing, hay baling moisture sensing, and more. They are also utilized in wind turbines, robotic systems, medical scanning equipment, antennas, motors, generators, pumps, conveyors, elevators, escalators, and numerous other applications. These units provide reliable connections in demanding conditions, making them a valuable asset in various industries.
