Magnetic Mating Interface
Confirm Pin count, contact allocation, magnet arrangement, connector shape, polarity control and mating direction.
This custom 4-pin double-ended magnetic pogo pin data cable uses detachable magnetic connector interfaces at both ends for project-specific power, signal, detection or communication functions. The Pin Map at each end, cable length, conductor gauge, wiring sequence, magnetic retention, mating direction, strain relief and device-side contact structure can be customized according to the approved schematic and mechanical drawing.
The finished assembly must define the magnetic mating component, internal conductor arrangement, cable construction and the opposite-end connection as one complete electrical system.
Confirm Pin count, contact allocation, magnet arrangement, connector shape, polarity control and mating direction.
Define cable length, conductor count, wire specification, shielding requirements, jacket and flexibility.
Select USB, Type-C, DC plug, bare wire, terminal, PCB connection or another customized termination.
Confirm installation space, outlet direction, strain relief, exposed-contact state and user operation.
Engineering Summary: This custom 4-pin double-ended magnetic pogo pin data cable integrates two detachable magnetic interfaces into one complete cable assembly. Both ends must be defined together, including the Pin Map, mating orientation, cable wiring, magnetic retention and device-side contact structure.
Unlike a conventional cable with one magnetic end and one standard plug, this assembly uses a magnetic connector at both ends. Each interface contains four electrical contacts that can be assigned to power, ground, data, detection or other project-specific functions.
| Assembly Element | Engineering Function |
|---|---|
| Magnetic End A | Provides the first detachable four-contact device interface |
| Magnetic End B | Provides the second detachable four-contact device interface |
| Four-Contact Pin Map | Defines power, return, signal, detection or identification functions |
| Cable Conductors | Connect the approved contact allocation between both ends |
| Connector Housings | Control alignment, seating and pogo pin working compression |
| Strain Relief | Reduces cable bending and pull loads at both connector exits |
Four contacts do not automatically define one universal protocol. A typical project may allocate the contacts to power, ground and a differential data pair, or use them for signal, detection and control functions.
The Pin Map at both ends must confirm whether the wiring is straight-through, mirrored or application-specific. Orientation and polarity should also be reviewed to prevent reverse connection during mating.
Engineering Note: Because the electrical path passes through two magnetic interfaces, voltage drop, contact resistance and signal performance should be evaluated across the complete cable assembly rather than at one connector end only.
| Specification | Product Definition |
|---|---|
| Product Type | Double-ended magnetic pogo pin data cable assembly |
| Pin Count | 4 contacts at each magnetic end |
| Electrical Function | Project-specific power, signal, detection or data allocation |
| Wiring Sequence | Straight-through, mirrored or custom according to the approved schematic |
| Cable Length | Customized according to device installation requirements |
| Wire Gauge | Selected according to current, signal and cable-length requirements |
| Magnetic Retention | Defined separately for both connector ends |
| Data Performance | Confirmed through complete end-to-end channel validation |
| Environmental Protection | Dependent on both mating interfaces and the complete device installation |
Yes, but the wiring may also be mirrored or customized. The final sequence must be defined in the approved schematic.
Yes, when the contact allocation, protocol, conductor structure and complete end-to-end channel are designed and validated for the application.
No. Four contacts alone do not confirm USB or another protocol. The internal wiring and connected electronics must also be reviewed.
Yes. Different retention or release requirements can be evaluated for each end according to the installation and user operation.
Submit your Pin Map, cable length, signal requirements and device-side drawings through the Get Quote & Samples page.
CTP can review both magnetic interfaces, the complete cable path, contact allocation, magnetic retention and device integration before prototype development.
A reference product image is not enough to define a cable assembly. Confirm the following information before drawing, sampling or quotation review.
The exact project route depends on whether an existing product can be used, modified or requires a new cable assembly design.
Confirm product scope, Pin Map, cable length, termination, quantity and application conditions.
Match magnetic contacts to conductors, source-side wiring and device-side functions.
Confirm dimensions, outlet direction, cable construction and required sample configuration.
Review electrical, mechanical and environmental conditions before production approval.
Submit the magnetic-end structure, electrical functions, cable length, conductor requirements, opposite-end interface, installation space and available drawings for project review.
Review related cable assemblies by contact count, shape, termination and project supply scope.
