Magnetic Mating Interface
Confirm Pin count, contact allocation, magnet arrangement, connector shape, polarity control and mating direction.
This custom 5-pin magnetic pogo pin cable assembly combines a linear five-contact magnetic interface with individual wire leads for PCB, module and device integration. The five contacts can be assigned to power, ground, signal, detection or identification functions according to the approved Pin Map, while the wire length and gauge, contact pitch, magnetic retention, housing, sealing structure and device-side mating interface can be customized for the project.
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 5-pin magnetic pogo pin cable assembly combines a linear five-contact magnetic interface with individual wire leads. The contacts can be allocated to power, ground, signals, detection or identification according to the approved Pin Map. Wire length, conductor size, magnetic retention, housing, sealing structure and the device-side mating interface should be confirmed together in the project drawing.
This product is a wire-ended magnetic cable assembly rather than only a connector component. Its five individual conductors provide a flexible interface for PCB, module and device integration without limiting the opposite end to a fixed USB connector.
The pogo pin contacts provide controlled electrical contact pressure, while the magnets assist capture and retention. Final orientation, alignment, working compression and mechanical stopping should still be controlled by the connector housing and device structure.
| Assembly Element | Engineering Function |
|---|---|
| Five-contact magnetic interface | Provides five project-defined electrical channels |
| Pogo pin contacts | Generate spring contact pressure against the mating targets |
| Magnetic structure | Assists connector capture and retention |
| Connector housing | Controls orientation, alignment and final seating |
| Five wire leads | Connect the five contacts to the customer PCB, module or harness |
| Strain relief and sealing structure | Protect the conductor exit according to the application requirements |
The five contacts do not have one universal electrical definition. Their functions should be confirmed from the customer schematic before the connector and wire harness are finalized.
| Example Architecture | Possible Contact Allocation |
|---|---|
| Power plus signal pair | Power, ground, two signal contacts and one detection contact |
| Parallel power paths | Two positive contacts, two return contacts and one identification contact |
| Charging and sensing | Power, ground, detection, identification and temperature sensing |
| 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.
| Specification | Product Definition |
|---|---|
| Product Type | Magnetic pogo pin power and data cable assembly |
| Pin Count | 5 Pin |
| Contact Layout | Linear five-contact layout |
| Opposite End | Five individual wire leads |
| Pin Map | Project-specific |
| Wire Length | Customized according to the installation structure |
| Wire Gauge | Selected according to current, cable length and voltage-drop requirements |
| Rated Current / Voltage | Confirmed by complete current-path and thermal validation |
| Contact Resistance | Measured at the defined working compression and test boundary |
| Magnetic Retention | Specified according to the device structure and release direction |
| Environmental Protection | Dependent on the complete connector and device sealing structure |
Electrical capability should be evaluated through the complete path, including the wire leads, contact terminations, pogo pin interface, mating targets and device PCB.
The project should define:
Five contacts can carry selected power and signal functions, but Pin count alone does not establish USB, UART, I2C, CAN or another protocol. The complete connector, PCB and wiring channel should be validated for the required communication function.
Magnetic performance should be divided into capture, retention and release rather than 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 5-pin magnetic data cable may be evaluated for:
Yes. The contacts may be allocated to power, ground and selected signal functions according to the approved Pin Map.
No. Five Pin only describes the number of physical contacts. USB or another protocol requires complete signal-channel validation.
Yes. Wire length, gauge, color, insulation and opposite-end processing can be selected according to the project.
No. An IP67 claim should only be used when the defined connector or installed device assembly has passed the corresponding test conditions.
Capture, retention and release should be defined separately according to the device structure, cable direction and intended operation.
Submit your Pin Map, wire requirements, electrical specifications and device-side drawings through the Get Quote & Samples page .
CTP can review the five-contact Pin Map, wire construction, magnetic structure, connector housing, sealing method 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.
