A custom 4 pin magnetic charging cable with a dual-row 2×2 pogo contact layout, protruding mating block and flange-like housing. The four contacts are assigned according to the approved Pin Map, while voltage, current, cable construction, opposite-end termination, working stroke and magnetic retention are project-specific. Charging-current capability must be validated through the complete conductive path.
The finished assembly must define the magnetic mating component, internal conductor arrangement, cable construction and the opposite-end connection as one complete electrical system.

4 PIN DUAL-ROW MAGNETIC CHARGING CABLE
This 4 pin magnetic charging cable is a complete cable assembly with four spring-loaded contacts arranged in a dual-row 2×2 layout. The visible structure combines a protruding rectangular mating block, a flange-like mechanical housing and an integrated cable connection.
The four contacts are assigned according to the approved Pin Map. Charging is the confirmed function of this product, while power, return, detection, control or signal allocation should be defined for each contact before the cable is released for a specific device.
Magnets primarily assist capture and retention during mating. Final position, alignment and seating should be controlled by the mating housing and mechanical geometry, while the pogo contacts provide electrical connection and controlled Z-axis compliance.
The magnetic cable head uses four electrical contacts arranged as two contacts per row. This 2×2 layout provides a compact interface for project-defined charging and auxiliary electrical functions.
The exact X pitch, Y pitch, Pin 1 position and electrical allocation should be shown on the approved drawing. Pin count and physical arrangement alone do not establish the electrical function of each contact.
Pin Count Four spring-loaded contacts
Contact Layout Dual row / 2×2 arrangement
Front Interface Protruding rectangular mating block
Primary Function Project-defined charging interface
The product image shows a flange-like outer housing around the central contact block together with visible fastening or mounting features.
The exact mounting method should be defined by the approved mechanical drawing. Housing X/Y/Z dimensions, mounting-hole geometry, mating depth, cable outlet direction and the available device-side installation space should be reviewed together.
Mechanical datums, guides and seating surfaces should establish the final connector position. The spring-loaded contacts should not be used as the primary mechanical stop.
The approved drawing should identify Pin 1, viewing direction and the electrical function of all four contacts.
Four contacts do not automatically mean that all four pins are connected in parallel for power delivery. Depending on the system architecture, contacts may be assigned to power, return, detection, control or other project-specific functions.
If two or more contacts are paralleled for the same power path, current sharing must be evaluated. Contact resistance, conductor resistance, mating compression, mechanical tolerance and temperature can cause unequal current distribution.
The four spring-loaded contacts should operate within the approved working stroke after the connector housing reaches its intended seated position.
Working stroke and total travel are different parameters. Working stroke defines the intended operating compression, while total travel represents the maximum available mechanical movement of the spring contact.
Contact height, X/Y position, mating-block geometry, device-side position and housing tolerances should be considered together when defining the normal compression condition.
The pogo contacts provide electrical connection and controlled axial compliance. They should not function as the primary hard stop of the assembly.
The magnetic structure assists the two mating components during approach and helps retain the interface after engagement.
Capture force, retention force, separation force and peel force describe different mechanical conditions. The required magnetic behavior should be selected according to the complete device geometry and intended release direction rather than by maximizing magnetic attraction.
Final alignment and seating should be controlled by the mechanical mating geometry. Magnetic attraction alone should not determine final pogo pin compression or establish a valid electrical connection.
Charging-current capability cannot be determined from the number of pogo contacts, contact diameter or gold-colored appearance alone.
Power Source → Opposite-End Termination → Cable Conductors → Magnetic Cable Head → Pogo Contacts → Mating Interface → Device PCB → Charging Circuit → Load / Battery
Vdrop = I × Rpath
Ploss = I² × Rpath
Cable length, wire gauge, termination resistance, pogo contact resistance, mating compression, device-side PCB copper and temperature rise should be evaluated together before releasing a continuous-current rating.
Continuous current and peak current should be defined separately. If contacts are paralleled, the complete assembly should also be validated for current sharing.
Charging is the confirmed function of this four-pin cable. The presence of four contacts does not automatically establish USB or another data protocol.
If signal or data functions are required, the Pin Map, return path, contact geometry, PCB transition, cable conductor arrangement, shielding and complete electrical channel should be evaluated together.
A data protocol or supported data rate should only be stated after complete-channel validation.
The magnetic charging head is only one part of the complete cable assembly.
Cable length, conductor count, wire gauge, outer jacket, cable flexibility, strain relief and opposite-end termination should be defined according to the electrical and mechanical requirements of the finished device.
USB-A, USB-C, DC plug, bare wire, terminal or another interface should only be stated after the approved cable drawing confirms the actual configuration.

This 4 pin dual-row magnetic charging cable can be evaluated for equipment requiring a detachable charging interface together with a defined mechanical housing and compact four-contact arrangement.
Final suitability depends on the approved Pin Map, charging current, cable construction, mechanical installation, mating geometry and environmental requirements.
Environmental performance should be validated for the complete magnetic cable and installed mating interface under defined test conditions.
Corrosion behavior, mating-cycle capability, cable bending life and operating-temperature capability depend on the exact materials, plating, cable construction and application conditions.
Gold-colored contacts do not establish a specific plating specification, corrosion rating or environmental qualification. An IP rating should only be claimed when the complete mating and sealing structure has been defined and tested.
It is a magnetic charging cable assembly using four spring-loaded electrical contacts arranged in a two-row 2×2 layout. The exact electrical function of each contact is defined by the approved Pin Map.
Contacts may be assigned to power, return, detection, control or other project-specific functions. The four-pin layout does not define one universal electrical configuration.
Parallel contacts can be evaluated, but current should not be assumed to divide equally. Contact resistance, conductor resistance, compression tolerance and temperature can affect current sharing.
Charging current is project-specific and must be validated through the complete conductive path, including cable conductors, terminations, pogo contacts, mating interface, device PCB and charging circuit.
Contact appearance alone does not establish the plating specification. Contact material, plating type and plating thickness should be confirmed from the approved BOM or drawing.
USB or data capability should not be assumed from the four-pin interface. Any protocol or data rate must be evaluated from the Pin Map, return path, cable construction and complete electrical channel.
The magnetic structure primarily assists capture and retention. Final alignment, position and seating should be controlled by the mechanical mating geometry.
Working stroke is defined by the approved drawing and represents the intended operating compression. It should be distinguished from total mechanical travel.
Yes. Housing dimensions, mounting geometry, cable length, wire construction, cable outlet and opposite-end termination can be defined according to the approved project requirements.
