Magnetic Mating Interface
Confirm Pin count, contact allocation, magnet arrangement, connector shape, polarity control and mating direction.
A custom 3 pin magnetic data cable assembly with a compact molded cable head and a matching pogo pin contact interface for detachable device connections. The three contacts are assigned according to the approved Pin Map, while cable length, conductor construction, opposite-end termination, magnetic retention and device-side mounting are project-specific. Data protocol and supported data rate must be validated through the complete electrical channel.
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.
3 PIN MAGNETIC DATA CABLE ASSEMBLY
This 3 pin magnetic data cable is a complete cable assembly rather than an individual magnetic connector. The visible structure combines a compact molded cable head, a three-contact magnetic mating interface, cable conductors and a separate device-side mating component.
The three electrical contacts are assigned according to the approved Pin Map. They may be allocated to data, signal, power, return, detection or control functions according to the project, but the pin count alone does not establish a specific protocol or data rate.
Magnetic structures assist capture and retention during mating. Final position, alignment and seating should be controlled by the connector housings and mechanical mating geometry, while the pogo contacts provide electrical connection and controlled Z-axis compliance.
A magnetic data cable should be evaluated as one complete electrical and mechanical system rather than only by the magnetic connector head.
Magnetic Interface Three-contact detachable magnetic mating interface
Cable Construction Conductor count, gauge, shielding and jacket are project-specific
Opposite Termination Defined by the approved cable drawing
Electrical Functions Data, signal, power, return, detection or control according to Pin Map
The product uses three electrical contact positions in a compact linear arrangement. The cable-side molded head has a recessed mating face, while the product image also shows a separate device-side mating component with corresponding pogo pin contacts.
The exact Pin 1 location, viewing direction and electrical allocation must be shown on the approved drawing. Mirrored viewing directions between the cable side and device side can create wiring errors if the Pin Map is not defined from a consistent reference direction.
Male and female terminology should not be assumed from appearance. For engineering documentation, CTP recommends identifying the interfaces as the cable-side magnetic interface and the device-side mating component unless the approved drawing defines another naming convention.
This product is intended for data-interface applications, but three contacts do not define one universal data architecture.
The project should identify the function of every contact, including data, signal return, power, ground, detection, identification or control where applicable.
Supported data protocol and data rate must be evaluated through the complete electrical channel, including:
A three-pin magnetic interface should therefore not be described as supporting a specific USB, UART, I²C or other protocol unless the complete system has been designed and validated for that function.
The magnetic structure assists the two mating components during approach and helps retain the interface after engagement.
Magnetic capture, retention, separation and peel behavior are different mechanical conditions and should be specified according to the actual device structure. A stronger magnetic force is not automatically a better design.
Final connector position and alignment should be controlled by the mating housing, mechanical datums, guides and seating surfaces. Magnetic attraction alone should not be used to define final contact compression.
The spring-loaded contacts require an approved working stroke after the cable head and device-side mating component reach their intended seated position.
Working stroke should be distinguished from total mechanical travel. The recommended operating compression must consider housing tolerances, PCB position, contact height, mating-surface variation and the final mechanical stack-up.
Pogo pins should provide electrical contact and controlled compliance rather than function as the primary mechanical stop.
The magnetic connector head is only one part of the cable assembly. Cable length, conductor count, conductor gauge, shielding, outer jacket, flexibility and strain-relief structure should be defined together with the device requirements.
The opposite end of the cable may use a project-specific termination, but the exact interface should be confirmed before the product is described as USB-A, USB-C, DC, terminal, bare wire or another standard connection.
Cable routing and repeated bending conditions should also be included in the project requirements when the cable operates in a moving or frequently handled application.
If one or more of the three contacts are also used for power delivery, current capability must be evaluated through the complete conductive path.
Source → Opposite-End Termination → Cable Conductors → Magnetic Cable Interface → Pogo Contact Interface → Device PCB → Load
Vdrop = I × Rpath
Ploss = I² × Rpath
Wire gauge, cable length, connector resistance, contact condition, PCB copper and temperature rise should be reviewed together. Current capability cannot be determined from pogo pin size alone.

CTP can review the complete 3 pin magnetic data cable architecture around the customer’s electrical functions, mechanical space and cable requirements.
This three-contact magnetic data cable architecture can be evaluated for products that require a detachable cable connection together with defined signal, data, control or combined electrical functions.
Application suitability depends on the approved Pin Map, signal requirements, magnetic interface, cable construction, mechanical integration and environmental validation.
Environmental performance should be specified for the complete cable and device-side interface rather than inferred from contact appearance or housing shape.
Corrosion resistance, mating-cycle capability, cable bending life, operating temperature and other reliability requirements should be validated under defined test conditions.
An IP rating should only be applied when the complete mating assembly and device sealing structure have been defined and tested according to the required protection level.
This product is a complete 3 pin magnetic data cable assembly. The magnetic connector head is only one part of the cable system, which also includes conductors, cable construction, opposite-end termination and the device-side mating interface.
The function of each contact is defined by the approved Pin Map. Contacts can be allocated to data, signal, return, power, ground, detection or control functions according to the project.
A USB function should not be assumed from the three-pin interface alone. The required protocol, Pin Map, return path, cable construction, source electronics and receiving electronics must be defined and validated as a complete data channel.
Data rate is project-specific. It depends on the signal protocol, Pin Map, return path, contact geometry, PCB transitions, cable length, conductor arrangement, shielding and the complete connected channel.
Combined power and data functions can be evaluated when the three-contact Pin Map and complete electrical architecture support the required functions. Current capability and signal performance must be validated independently.
The magnets assist capture and retention. Final position, alignment and seating should be controlled by the mating housing and mechanical geometry rather than magnetic force alone.
Yes. Cable length, conductor construction and opposite-end termination can be defined according to the approved project requirements and drawing.
A separate device-side mating component is shown in the product image, but the exact supply scope should be confirmed during quotation and drawing review.
No IP rating should be assumed for the cable from its appearance. Environmental protection depends on the complete mating connector, cable housing, device sealing structure and validated assembly.
Provide the Pin Map, required data or signal function, protocol, cable length, wire requirements, opposite-end termination, voltage, current, device-side mating geometry, magnetic requirements, environmental conditions and available 2D or 3D drawings.
