ROUND MAGNETIC CONNECTOR PAIR
This round magnetic connector is a mating connector pair with a concentric circular interface. One connector half is configured with a cable lead, while a separate cylindrical mating connector forms the opposite side of the interface.
One central contact position and a surrounding concentric ring structure are visible. The actual electrical contact count and the function of the outer ring must be defined by the approved wiring and connector drawings.
Magnets primarily assist capture and retention during mating. Final position, alignment and seating should be established by the circular housing, mating surfaces and mechanical datums rather than by magnetic attraction alone.
The visible assembly consists of a cable-terminated round connector and a separate mating connector. This should be treated as a magnetic connector pair rather than automatically classified as a finished magnetic charging cable.
Connector Type Round magnetic connector pair
Cable-Side Cable-terminated connector half
Mating Side Separate circular connector
Geometry Concentric round interface
One central electrical contact position is visible, but the complete electrical contact count cannot be determined from the product image alone.
The approved wiring diagram should identify the electrical function of the center contact, the surrounding ring and every conductive path through the connector pair.
Center Contact Function → To Be Confirmed
Outer Ring Function → To Be Confirmed
Complete Return Path → Defined by Approved Wiring Diagram
If the surrounding ring is used as an electrical return contact, its material, surface finish, mating resistance, termination method and mechanical seating condition should be included in the complete electrical validation.
One connector half is visibly terminated to a cable lead. Cable length, wire gauge, conductor count, cable jacket, strain relief and the opposite end of the cable should be defined according to the project.
The mounting and termination method of the separate mating connector must also be confirmed. PCB, FPC, wire, panel, housing or another structure should only be stated after the approved mechanical drawing defines the actual installation.
The connector pair and cable lead should be reviewed as part of the complete conductive and mechanical system rather than as isolated components.
The magnetic structure assists the two round connector halves during approach and helps retain the interface after engagement.
Capture force, retention force, separation force and peel force describe different mechanical conditions. A single magnetic-force number should not be used without defining the mating condition and measurement direction.
Final position, alignment and seating should be established by the concentric housing geometry, mating surfaces and mechanical datums.
Stronger magnetic retention is not automatically better. The required holding and release behavior should be selected according to cable direction, device mass, mounting strength and expected user or machine interaction.
A round connector should not automatically be described as providing unrestricted 360-degree electrical mating.
Rotational freedom depends on the electrical symmetry of the center contact and outer ring, polarity requirements, mechanical keying and the mating-side connector architecture.
If rotational mating is required, the permitted rotation and electrical behavior should be defined in both the electrical and mechanical drawings.
The product image confirms a central contact position, but the internal spring-loaded mechanism cannot be determined from appearance alone.
If a pogo contact is used, the approved drawing should separately define working stroke, total travel, spring force and installed compression.
Working stroke represents the intended operating compression and should not be confused with total available travel.
The mechanical connector housing should establish the final seated position. A spring-loaded contact should provide electrical connection and controlled Z-axis compliance rather than act as the primary mechanical hard stop.
Current capability cannot be determined from the diameter of the round connector or center contact alone.
Source → Cable / Wire → Cable-Side Termination → Magnetic Connector Pair → Contact Interface → Mating-Side Termination → PCB / Wiring → Load → Confirmed Return Path
Vdrop = I × Rpath
Ploss = I² × Rpath
Wire gauge, cable length, termination resistance, center-contact resistance, return-path resistance, mating condition, PCB or device wiring and temperature rise should be evaluated together before releasing a continuous-current rating.
Continuous current and peak current should be specified separately when the application includes intermittent or transient loading.
Corrosion resistance, mating-cycle capability and operating-temperature performance depend on the actual contact materials, plating, housing, cable construction and operating environment.
A recessed circular interface does not by itself establish a waterproof rating.
An IP rating should only be stated after the complete connector pair, installation structure, device enclosure and sealing system have been defined and tested.

This round magnetic connector pair can be evaluated for products requiring a detachable circular power or charging interface with one connector half already terminated to a cable lead.
Final application suitability depends on the approved electrical architecture, mounting method, cable construction, mating geometry and environmental requirements.
This product is treated as a round magnetic connector pair. One connector half is cable-terminated, but the magnetic mating interface and separate mating component define the core connector architecture.
One central contact position is visible, but the actual electrical contact count must be confirmed because the surrounding ring may have an electrical, magnetic or mechanical function.
This cannot be confirmed from appearance alone. The outer-ring function and complete return path should be defined by the approved wiring diagram.
The visible reference configuration includes a cable-terminated connector half. Cable length, wire gauge, jacket and opposite-end termination should be defined according to the project.
Voltage and current are project-specific. Current capability should be validated across the complete conductive path, including the cable lead, connector contacts, return path, mating-side termination and device wiring.
Circular geometry alone does not establish unrestricted rotational mating. Contact symmetry, polarity, mechanical keying and the approved electrical architecture must be confirmed.
Capture force, retention force, separation force and peel force should be distinguished. The required value depends on the mating direction, cable routing, mounting structure and release behavior.
Yes. PCB, FPC, wire, cable or housing integration can be evaluated according to the approved electrical and mechanical design.
No IP rating should be assumed from the round or recessed connector shape. Environmental protection must be validated for the complete connector pair, device installation and sealing structure.
Provide the contact functions, return path, voltage, continuous and peak current, cable requirements, mating-side mounting method, available X/Y/Z space, connector dimensions, magnetic requirements and available 2D or 3D drawings.
