Magnetic Mating Interface
Confirm Pin count, contact allocation, magnet arrangement, connector shape, polarity control and mating direction.
This custom 5-pin magnetic pogo pin power and data cable combines a USB-A plug with a linear five-contact magnetic interface for charging, communication, detection or identification functions. The five-contact Pin Map, cable length, conductor gauge, data function, magnetic retention, connector housing, strain relief and device-side mating interface can be customized according to the approved project 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.

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 5-pin magnetic pogo pin cable combines a USB-A termination with a linear five-contact magnetic interface for power and validated data functions. The Pin Map, cable construction, magnetic retention, housing and device-side mating interface should be confirmed together in the approved project drawing.
This product is a complete magnetic cable assembly rather than only a magnetic connector head. It includes a USB-A plug, cable conductors, five spring-loaded contacts, a magnetic mating structure, molded housing and cable strain relief.
The pogo pins generate electrical contact pressure, while the magnetic structure assists connector capture and retention. Final orientation, working compression and mechanical stopping should be controlled by the connector housing and mating-device structure.
| Assembly Element | Engineering Function |
|---|---|
| USB-A plug | Connects the cable to an approved power source, host or project-specific interface |
| Five cable conductors | Carry the assigned power, ground, data, detection or identification functions |
| Five pogo pin contacts | Provide five spring-loaded electrical contact paths |
| Magnetic structure | Assists initial capture and connector retention |
| Connector housing | Controls contact position, orientation and final seating |
| Strain relief | Reduces cable bending and pulling loads at the connector exit |
The five contacts do not have one universal electrical definition. Their functions should be confirmed from the customer schematic and internal cable wiring before production.
| Example Architecture | Possible Contact Allocation |
|---|---|
| Power and data | Power, ground, two validated signal contacts and one detection contact |
| Charging with identification | Power, ground, detection, identification and temperature sensing |
| Parallel power paths | Two positive contacts, two return contacts and one detection contact |
| Project-specific interface | Five customer-defined power, signal or control functions |
These are planning examples only. The final Pin Map must follow the approved schematic and connector drawing.
Engineering Note: A USB-A plug and five magnetic contacts do not automatically establish a particular USB protocol or data rate. The internal wiring, contact allocation and complete cable-to-device channel must be validated.

Electrical performance should be evaluated through the complete path from the USB-A plug and cable conductors to the pogo pin contacts, mating targets and device PCB.
The project should define:
Where two contacts are assigned as a data pair, the cable conductors, magnetic connector transition, mating targets and PCB routing should be evaluated as one complete channel.
Magnetic performance should be defined through capture, retention and release requirements instead of one isolated force value.
Excessive magnetic attraction may increase mating impact, removal force and pogo pin compression. Magnetic force should therefore be selected together with the housing and intended user operation.
Yes. The contacts can be allocated to power, ground and selected data functions when the Pin Map and complete signal channel have been validated.
Not automatically. Supported functions depend on the internal wiring, contact allocation, device electronics and complete-channel validation.
The fifth contact may be used for detection, identification, temperature sensing, control or another project-specific function.
Yes. Cable length, conductor gauge, insulation, jacket and strain relief can be selected according to the electrical and installation requirements.
No. Environmental protection depends on the magnetic housing, cable entry, device-side installation and complete tested assembly.

CTP can review the five-contact Pin Map, USB-A wiring, cable construction, magnetic structure, connector housing and device-side mating interface before prototype development. Final specifications should be confirmed in the approved drawing and validation plan.
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.
