Magnetic Mating Interface
Confirm Pin count, contact allocation, magnet arrangement, connector shape, polarity control and mating direction.
This custom 5-pin magnetic pogo pin connector cable assembly combines a cable-side spring-loaded interface with a matching device-side contact for power, signal, detection or identification functions. The linear five-contact layout, Pin Map, pin pitch, cable length, wire gauge, magnetic retention, connector housing, overmolding and opposite-end termination 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.

Engineering Summary: This custom 5-pin magnetic pogo pin connector cable assembly combines a cable-side spring-loaded contact interface with a matching device-side contact. Five electrical channels can be assigned to power, ground, signal, detection, identification or other project-specific functions. The Pin Map, pitch, current path, cable construction, magnetic retention, housing and termination should be confirmed together in the approved project drawing.
This product is a complete magnetic connector assembly rather than only a connector head. It includes a five-contact magnetic mating interface, a cable-side housing and a matching device-side contact component.
The pogo pins provide controlled electrical contact pressure, while the magnetic structure assists mating and retention. Final alignment, pogo pin compression and mechanical stopping should still be controlled by the connector housing and device structure.
| Assembly Element | Engineering Function |
|---|---|
| Cable-side pogo pin interface | Provides five spring-loaded electrical contact paths |
| Device-side mating contact | Provides the corresponding fixed conductive targets |
| Magnetic structure | Assists initial capture and connector retention |
| Connector housing | Controls orientation, alignment and final seating |
| Cable and conductors | Carry the assigned power and signal functions |
| Overmold and strain relief | Protect the cable exit and reduce conductor loading |
The five contacts do not have a universal fixed function. Their electrical allocation should be defined from the customer schematic before the housing, cable and mating side are finalized.
| Example Architecture | Possible Contact Allocation |
|---|---|
| Power with detection | Two positive contacts, two return contacts and one detection contact |
| Power plus signal pair | Power, ground, two signal contacts and one detection or 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 electrical design.

| Product Type | Magnetic pogo pin connector cable assembly |
| Pin Count | 5 Pin |
| Contact Layout | Linear five-contact layout |
| Connector Sides | Cable-side pogo pin interface and device-side mating contact |
| Pin Map | Project-specific |
| Pin Pitch | Confirmed according to the approved drawing |
| Rated Current / Voltage | Confirmed according to the complete current path and thermal validation |
| Contact Resistance | Measured at the defined working stroke and test boundary |
| Magnetic Retention | Specified according to the device structure and release direction |
| Cable Length and Wire Gauge | Customized according to voltage drop, current and installation requirements |
| Opposite-End Termination | USB-A, USB-C, bare wire, PCB or customized termination |
| Environmental Protection | Dependent on the complete connector and device sealing structure |
Current capability depends on the complete path from the power source through the cable conductors, pogo pin contacts, mating targets and device PCB.
The project should define:
When two contacts are connected in parallel, current should not be assumed to divide equally. Contact resistance, pogo pin compression, target alignment and conductor routing should be evaluated together.
Five contacts may also support selected signal or data functions, but Pin count alone does not establish compatibility with USB or another protocol. The complete connector, PCB and cable channel must be validated for the required signal.
Magnetic force should be specified as part of the complete connector system rather than as one isolated value.
Engineering review should separate:
Stronger magnetic attraction is not automatically better. Excessive force may increase mating impact, removal force and pogo pin compression.
This connector assembly may be evaluated for:
Final application suitability depends on the approved electrical, mechanical and environmental requirements.
| Requirement | Recommended Evaluation |
|---|---|
| Pin Map | Continuity, polarity and contact-function verification |
| Working Compression | Minimum, nominal and maximum mating conditions |
| Power Operation | Voltage drop, current sharing and temperature rise |
| Signal Operation | Complete connector, PCB and cable channel evaluation |
| Magnetic Behavior | Capture, retention and release in defined directions |
| Cable Durability | Pull, bend, twist and strain-relief testing |
| Mechanical Operation | Project-defined mating-cycle test |
| Environmental Performance | Complete connector and device assembly testing |
It is a complete magnetic connector cable assembly with a cable-side pogo pin interface and a matching device-side contact.
Yes. The contacts may be allocated to power, ground and selected signal, detection or identification functions according to the approved Pin Map.
Yes. Cable length, wire gauge, USB-A, USB-C, bare-wire, PCB and selected custom terminations can be evaluated.
No. Environmental protection depends on the connector housing, cable entry, device-side installation and complete tested assembly.
Capture, retention and release should be defined separately according to the device structure, cable direction and intended user operation.

CTP can review the five-contact Pin Map, pin pitch, current path, magnetic structure, cable construction, housing, overmolding 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.
