Magnetic Mating Interface
Confirm Pin count, contact allocation, magnet arrangement, connector shape, polarity control and mating direction.
This custom 2-pin magnetic pogo pin cable assembly combines a two-contact magnetic interface with a USB-C termination for compact device integration. The two contacts can be assigned to power, return, detection or a validated project-specific signal function according to the approved wiring diagram. Cable length, conductor gauge, magnetic retention, connector housing, strain relief and the device-side mating interface can be customized for the application.
The finished assembly must define the magnetic mating component, internal conductor arrangement, cable construction and the opposite-end connection as one complete electrical system.

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 2-pin magnetic pogo pin cable combines a two-contact magnetic interface with a USB-C termination. The contacts can be assigned to power, return, detection or a validated project-specific signal function according to the approved wiring diagram. Cable construction, magnetic retention, housing and the device-side mating interface should be confirmed as one complete system.
This product is a complete magnetic cable assembly rather than only a magnetic connector head. It includes a two-contact magnetic mating interface, cable conductors, connector housing, strain relief and a USB-C termination.
The spring-loaded contacts generate electrical contact pressure, while the magnets assist initial capture and retention. Final orientation, working compression and mechanical stopping should still be controlled by the connector housing and device structure.
| Assembly Element | Engineering Function |
|---|---|
| Two spring-loaded contacts | Provide two project-defined electrical paths |
| Magnetic structure | Assists connector capture and retention |
| Connector housing | Controls orientation, alignment and final seating |
| Cable conductors | Connect the magnetic interface to the USB-C termination |
| USB-C termination | Connects to an approved power source or project-specific host interface |
| Strain relief | Reduces cable bending and pulling loads at the connector exits |
The two contacts do not have one universal electrical function. Their allocation must be confirmed from the customer schematic and internal cable wiring.
| Possible Architecture | Contact Allocation | Required Validation |
|---|---|---|
| Charging cable | Positive power and return | Polarity, voltage drop, temperature rise and short-circuit protection |
| Detection interface | Detection signal and reference return | Logic level and valid-mating recognition |
| Single-wire communication | Signal and reference ground | Protocol, timing, signal level and complete-channel testing |
| Project-specific interface | Two customer-defined functions | Approved schematic and wiring diagram |
Engineering Note: Two physical contacts do not automatically provide simultaneous charging and data transfer. Publish “power and data” only when the actual circuit and communication function have been validated.

Electrical performance should be evaluated through the complete path from the USB-C source, cable conductors and spring-loaded contacts to the device-side mating pads and PCB.
The project should define:
Where signal transmission is required, also define the protocol, signal level, reference path, required data rate and acceptance criteria.
Magnetic performance should be divided into capture, retention and release instead of being represented by one isolated force value.
Stronger magnetic attraction is not automatically better. Excessive force may increase mating impact, removal force and pogo pin compression.
This 2-pin magnetic cable may be evaluated for:
Not automatically. Two contacts are commonly used for positive power and return. Simultaneous power and data requires a project-specific communication architecture and complete-channel validation.
No. A USB-C plug can be used as a physical power-source connection without implementing USB data functions. Internal wiring and electronics must be confirmed.
Yes. Cable length, conductor gauge, jacket, strain relief and opposite-end termination can be selected according to the project.
No. An IP rating should only be stated when the defined connector or installed device assembly has passed the applicable test conditions.
Capture, retention and release should be specified separately according to the device structure, cable direction and intended operation.
Submit the wiring diagram, cable requirements, electrical specifications and device-side drawing through the Get Quote & Samples page .
CTP can review the two-contact 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.
