Pin Map and Contact Functions
Define the function of each power, return, signal, control or detection contact.
This custom 1-pin round magnetic pogo pin connector pair combines a central spring-loaded contact with a compact circular mating structure for project-specific power, signal, detection or identification interfaces. The center-contact function, outer-body function, mounting method, working compression, spring force, magnetic retention, terminal structure and device integration can be customized according to the approved schematic and mechanical drawing.
Product specifications should be reviewed together with the customer device, PCB, electrical assignment and mechanical mating conditions.

Engineering Summary: This custom 1-pin round magnetic pogo pin connector pair combines a central spring-loaded contact with a compact circular mating structure. The center-contact function, outer-body function, mounting method, magnetic retention and working compression must be defined together in the approved project drawing.
The term “1 Pin” refers to the central pogo pin. It does not automatically mean that the complete interface has only one conductive path. The surrounding metal structure may provide magnetic attraction, mechanical alignment, an electrical return path or a combination of these functions, depending on the product design.
The pogo pin provides controlled electrical contact pressure, while the magnetic structure assists initial capture and retention. Final seating and working compression should be controlled by the connector housing and mating-device structure.
| Assembly Element | Engineering Function |
|---|---|
| Central pogo pin | Provides one spring-loaded electrical contact path |
| Surrounding metal structure | Function confirmed according to the electrical and mechanical drawing |
| Round magnetic housing | Assists capture, alignment and retention |
| Matching connector half | Provides the corresponding mating contact and mechanical interface |
| Rear terminals | Connect the assembly to the PCB, wire or device circuit |
Before prototype development, the project must confirm whether the connector is used for power, signal, detection or another function.
Engineering Note: A current rating should be validated across the complete electrical path, including the center contact, return path, terminals, PCB or wire, mating connector and device load.

Not necessarily. One Pin normally describes the central pogo contact. The outer metal structure may provide another conductive path, but this must be confirmed from the wiring drawing.
Yes, when the complete current and return paths are defined and validated for voltage drop and temperature rise.
Yes, when the signal path, reference path, logic level and connected electronics are clearly defined.
Yes. PCB terminals, wire connections, panel installation, connector diameter and housing structure can be customized.
Submit your schematic, current or signal requirements, mounting dimensions and mating-interface drawing through the Get Quote & Samples page.
CTP can review the contact path, terminal structure, working compression, magnetic retention and device integration before prototype development.
This product page presents a CTP magnetic connector configuration for engineering reference. Final dimensions, electrical ratings, materials, magnet structure, sealing level and reliability targets are not universal values; they are confirmed against the approved drawing, installation condition and model-specific validation plan.
CTP reviews the application and prepares a drawing or specification for approval before sample production. Test scope, acceptance criteria and report format should identify the model, sample status, method, conditions, result and review date.
Yes. Customization can cover geometry, contact layout, materials, cable construction, magnetic structure, sealing and appearance. Feasibility depends on the application and approved specification.
No. Current, voltage, resistance, temperature rise and ingress-protection claims apply only to the identified model and stated test conditions.
Timing is confirmed after the drawing, materials, tooling, sample quantity, validation scope and production requirements have been reviewed.
ENGINEERING CONFIRMATION BEFORE SAMPLING
