ROUND MAGNETIC DATA CABLE
This round magnetic data cable is a custom cable assembly with a compact concentric mating interface, a separate round mating component and a side-exit cable structure.
Data and signal transmission are the confirmed functional direction of this product. The exact electrical contact count, Pin Map, return or reference path, data protocol, required data rate and cable construction must be defined according to the approved project requirements.
Magnets primarily assist capture and retention during mating. Final position, alignment and seating should be established by the round housing, mating surfaces and mechanical datums rather than magnetic attraction alone.
The visible cable-side component uses a cylindrical round housing with a concentric mating face and a cable routed from the side of the connector body.
The side-exit architecture can be evaluated when the equipment layout requires the cable to route parallel to the device surface instead of extending directly along the connector mating axis.
Interface Shape Round / circular
Mating Geometry Concentric interface
Cable Routing Side / radial cable exit
Primary Function Data / signal transmission
One central contact position is visible in the reference image, together with a surrounding concentric ring. The complete electrical contact count cannot be determined from appearance alone.
The approved Pin Map should identify every signal, return, reference, power, detection or unused conductive path in the magnetic interface.
Visible Center Contact → Confirmed
Outer Ring Electrical Function → To Be Confirmed
Complete Pin Map → Defined by Approved Drawing
If the outer ring participates in the signal return or reference path, its contact geometry, termination and interface resistance should be included in the complete channel design.
The number of contacts does not determine data bandwidth. Data capability depends on the complete electrical channel rather than the magnetic connector alone.
Source / Host → PCB Transition → Cable Termination → Cable Conductors → Magnetic Contact Interface → Mating Component → Device PCB Transition → Receiver
The engineering review should consider the Pin Map, return or reference path, contact geometry, cable length, conductor arrangement, shielding requirements, connector transitions and receiver requirements together.
USB, UART, I²C, SPI, CAN, proprietary signaling or any specific data rate should only be stated after the complete channel architecture has been confirmed.
A valid data interface requires a defined signal reference or return path. The function of the central contact and surrounding ring should therefore be confirmed before the cable architecture is released.
Cable conductor count, wire gauge, conductor arrangement, shielding, cable length and outer jacket should be selected according to the required electrical channel and mechanical environment.
When shielding or controlled signal geometry is required, it should be defined as part of the complete cable and connector channel rather than inferred from the round connector shape.
The side cable exit changes how the cable load is transferred into the magnetic head and how the assembly fits into the equipment envelope.
Cable outlet direction, strain relief, bend radius and available X/Y/Z space should therefore be reviewed together with the connector position and device housing.
The mating connector installation method should also be confirmed from the device drawing. PCB, FPC, wire, housing or another integration method should not be assumed from the reference image.
The magnetic structure assists approach and retention between the round mating components.
Capture force, retention force, separation force and peel force describe different mechanical conditions and should be specified separately when relevant to the project.
Final position, alignment and electrical seating should be controlled by the mechanical mating geometry and housing datums.
Stronger magnetic retention is not automatically better for a data interface. Excessive retention can change release behavior and mechanical loading without improving the electrical channel.
The reference image confirms a central contact position but does not establish whether the contact uses a spring-loaded pogo structure.
If a pogo contact is used, working stroke, total travel, spring force and installed compression should be defined separately in the approved drawing.
Working stroke represents the intended operating compression and should not be confused with total mechanical travel.
Spring-loaded contacts should provide electrical connection and controlled Z-axis compliance rather than serve as the primary mechanical hard stop.
Data / signal function is confirmed for this product, but power or charging capability should be defined separately if the same cable is expected to carry both data and power.
Current capability must be evaluated through the complete conductive path rather than inferred from connector diameter or contact appearance.

This round magnetic data cable can be evaluated for compact devices requiring a detachable signal interface and side-directed cable routing.
Final application suitability depends on the required signal architecture, complete electrical channel, cable construction, mechanical integration and environmental conditions.
This product is defined as a round magnetic data cable assembly. Any additional power or charging function should be confirmed separately by the approved Pin Map and electrical requirements.
One central contact position is visible, but the complete electrical contact count must be confirmed because the surrounding ring may have an electrical, magnetic or mechanical function.
No. Data capability depends on the Pin Map, return or reference path, contact geometry, cable construction, terminations, PCB transitions and complete electrical channel.
The protocol must be defined for the project. USB, serial buses or proprietary signaling should only be specified after the complete channel requirements have been reviewed.
The side-exit architecture can support device layouts where cable routing is required parallel to the mounting surface or where axial cable clearance is limited.
This must be defined by the Pin Map and complete electrical design. Power capability should be evaluated separately from data performance and validated through the complete conductive path.
The image confirms a central contact position, but the internal spring-loaded mechanism, working stroke and total travel must be confirmed by the approved contact drawing.
Not automatically. Magnets primarily provide capture and retention. Signal performance depends on the electrical contact condition and complete channel design, while final seating is controlled by the mechanical interface.

CTP reviews the application and prepares a drawing or specification for approval before sample production. Test scope, acceptance criteria and report format should identify the model, sample status, method, conditions, result and review date.
