Confirm installation space, outlet direction, strain relief, exposed-contact state and user operation.
1 PIN RECESSED ROUND MAGNETIC CHARGING CABLE
This 1 pin round magnetic charging cable is a complete cable assembly with one central electrical contact, a recessed circular mating face and a visible concentric outer ring.
The term “1 Pin” identifies the central contact count. It does not by itself define the complete charging circuit. The electrical function of the outer ring or any other return-path structure must be confirmed by the approved wiring diagram.
Magnets primarily assist capture and retention during mating. Final position, alignment and seating should be established by the circular housing and mechanical mating geometry rather than magnetic attraction alone.
The visible charging head uses a round housing with a recessed mating face. One central electrical contact is visible inside the recessed area, together with a concentric outer ring.
The recessed geometry can be evaluated when a device requires a compact circular charging interface and the housing must help control final mating position and contact protection.
Pin Count One central electrical contact
Interface Shape Round / circular
Mating Face Recessed concentric geometry
Primary Function Project-defined charging interface
A charging interface requires a complete conductive loop. One visible central contact therefore does not by itself define the complete power and return architecture.
The approved wiring diagram should identify the electrical function of the central contact, the concentric outer ring and any additional conductive structure used to complete the circuit.
If the outer ring is used as the return path, its contact material, surface finish, mating geometry, cable connection and interface resistance should be evaluated as part of the complete electrical system.
If the outer ring is not an electrical contact, another defined return path is required.
Center Contact Function → To Be Confirmed
Outer Ring Function → To Be Confirmed
Complete Return Path → Defined by Approved Wiring Diagram
The magnetic structure assists the charging head during approach and helps retain the interface after engagement.
Capture force, retention force, separation force and peel force describe different mechanical conditions and should not be represented by one undefined magnetic-force value.
Final position, alignment and seating should be controlled by the circular housing, mechanical datums and mating surfaces. Magnetic attraction alone should not define the final electrical contact condition.
Stronger magnetic retention is not automatically better. The required holding and release behavior should be selected around the device structure, cable handling and intended separation direction.
The product image confirms one central electrical contact position, but the internal spring-loaded structure and mechanical travel cannot be determined from appearance alone.
If the center contact uses a pogo pin, the approved drawing should define the working stroke, total travel, spring force and installed compression condition.
Working stroke and total travel are different parameters. Working stroke defines the intended operating compression, while total travel represents the available mechanical movement of the spring-loaded contact.
The mating housing should establish the final mechanical seating condition. A spring contact should provide electrical connection and controlled Z-axis compliance rather than serve as the primary mechanical hard stop.
Charging-current capability cannot be determined from the center-contact diameter, round housing size or one-pin description alone.
Power Source → Opposite-End Termination → Cable Conductors → Round Magnetic Cable Head → Center Contact + Confirmed Return Path → Device-Side Interface → PCB / Charging Circuit → Battery / Load
Vdrop = I × Rpath
Ploss = I² × Rpath
Cable length, wire gauge, termination resistance, center-contact resistance, return-path resistance, mating condition, device-side PCB copper and temperature rise should be evaluated together before a continuous-current rating is released.
Continuous current and peak current should be defined separately when the charging system includes transient or intermittent loading.
The round magnetic charging head is only one part of the complete cable assembly.
Cable length, conductor count, wire gauge, conductor material, outer jacket, strain relief and opposite-end termination should be defined together with the charging requirements of the device.
USB-A, USB-C, DC plug, terminal, bare wire or another custom interface should only be stated after the approved cable drawing confirms the actual configuration.
A round housing, recessed mating face or visible sealing feature does not by itself establish a waterproof or dust-protection rating.
Environmental protection must be evaluated for the defined complete assembly, including the cable head, mating component, device enclosure, seals, installation condition and test configuration.
An IP rating should only be published after the relevant complete assembly has been defined and validated to the required test level.
Contact corrosion behavior, cable durability and environmental capability should also be specified separately from the IP rating.

This 1 pin recessed round magnetic charging cable can be evaluated for devices requiring a compact detachable power interface with a circular mating geometry.
Final application suitability depends on the complete charging path, return-path design, cable construction, mechanical interface, magnetic behavior and environmental requirements.
It refers to the one central electrical contact visible in the round mating interface. It does not by itself define the complete number of conductive paths in the charging circuit.
The complete return path must be defined by the approved wiring diagram. The function of the concentric outer ring or any other conductive return structure should be confirmed before the cable architecture is released.
A concentric outer ring is visible, but its electrical function cannot be confirmed from appearance alone. Its function should be defined by the approved wiring and mechanical drawings.
The image confirms one central electrical contact position, but the spring-loaded mechanism, working stroke and total travel should be confirmed from the contact drawing.
Charging current is project-specific and must be validated across the complete conductive path, including the cable conductors, source termination, center contact, confirmed return path, device-side interface and charging circuit.
This should not be assumed from the circular appearance. Permitted rotation depends on the electrical function of the center contact and outer ring, polarity requirements and the approved mechanical design.
The magnetic structure primarily assists capture and retention. Final position, alignment and seating should be controlled by the mechanical mating geometry.
An IP rating should only be stated for a defined and validated complete assembly. The cable head, mating component, device enclosure, sealing structure and test configuration should be confirmed before publishing an IP rating.
Yes. Cable length, wire construction, cable outlet and opposite-end termination can be defined according to the approved project requirements.
