An individual double ended pogo pin with rounded contact geometry at both ends for customer-defined two-sided compression interfaces. The spring-loaded architecture provides controlled axial compliance while the surrounding housing or mechanical structure establishes final positioning. Working stroke, spring force, dimensions, materials, plating and electrical capability are defined by the approved project drawing.
Determine whether the project needs a single spring-loaded contact, a multi-contact connector assembly, a specific mounting method or a customer-defined mechanical interface.

This rounded tip double ended pogo pin is an individual spring-loaded electrical contact with contact interfaces at both ends. The visible design uses rounded contact geometry on each side of a straight cylindrical body.
The double-ended architecture can be evaluated for customer-defined compression interfaces where electrical continuity is required between two mating conductive surfaces. Although the component has two contact ends, it remains one electrical contact component rather than a two-pin connector.
Final positioning should be controlled by the surrounding housing, mechanical datums, guides or stops. The pogo pin provides electrical contact and controlled axial compliance and should not be used as the primary structural stop.
Rounded contact tips can provide a defined local contact interface when the mating surface geometry is compatible with the selected plunger shape. The actual contact condition depends on mating angle, compression, surface geometry, material and plating specifications.
Product Type Individual double ended pogo pin
Contact Ends Rounded contact geometry at both ends
Electrical Contact Count One contact component
Mechanical Function Controlled axial compliance
In a double-ended contact architecture, one end interfaces with the first mating conductive surface while the opposite end interfaces with a second conductive surface.
Spring compliance allows the contact system to accommodate a defined amount of axial stack-up variation. However, physical contact alone does not ensure the correct operating condition. The assembly must reach its intended mechanical seating position and place the spring-loaded contact within its approved working range.
Mechanical datums, guides and housing stops should therefore establish final position and alignment.
A stepped or enlarged mechanical feature is visible near one end of the product. Its exact function should be confirmed from the approved drawing rather than assumed from appearance.
Depending on the project architecture, the contact may be integrated into a customer-defined housing or mechanical support structure. The design should establish the installed height, center position, mating tolerance and allowable compression of the spring contact.
The pogo pin should not be relied upon to define the primary hard stop of the product assembly.
Working stroke and total mechanical travel are different parameters and should be specified separately.
Working stroke defines the intended operating compression under normal mating conditions. Total travel describes the available mechanical movement of the spring structure and should not automatically be treated as the recommended operating range.
For a double ended pogo pin, engineers should also confirm how movement is distributed between End A and End B. It should not be assumed that both ends have identical stroke or spring-force behavior unless this is defined by the approved drawing.
Current capability cannot be determined from the diameter, rounded tip geometry or visual size of the pogo pin alone. The complete conductive path must be evaluated.

Additional PCB traces, solder joints, cables, FPC or connector interfaces may also contribute resistance depending on the final system architecture.
Vdrop = I × Rpath
Ploss = I² × Rpath
Current capability should be validated using the complete path resistance, contact condition, temperature rise and application duty cycle rather than inferred from pogo pin dimensions.
The contact can be assigned to power, ground, control or signal functions according to the system design.
A rounded contact tip or double-ended structure does not define supported data bandwidth. For signal applications, engineers should evaluate the complete channel including return path, contact geometry, adjacent contacts, pitch, PCB transitions and any connected FPC or cable structure.

This rounded tip double ended pogo pin can be evaluated where a customer requires a compliant electrical contact between two conductive mating surfaces.
Suitability depends on the mating surface geometry, installed height, alignment, working stroke, spring force, electrical requirements and mechanical tolerance of the complete assembly.

CTP can review the required contact geometry against the customer’s mechanical envelope, mating surface, installed height, working stroke and electrical path.
Depending on engineering feasibility, the approved project drawing can define plunger geometry, barrel dimensions, spring characteristics, retention structure, material and surface finish requirements.
If the project requires multiple electrically separate contacts in a common insulating structure, review pogo pin connector assemblies rather than treating one double ended contact as a multi-pin connector.
It is an individual spring-loaded electrical contact with contact interfaces at both ends and rounded contact geometry visible at the mating ends.
No. It has two contact ends but remains one electrical contact component. It is different from a two-pin connector containing two electrically separate contacts.
Rounded contact geometry can be evaluated when the mating-surface design requires a localized contact point. Final suitability depends on the mating surface, compression, alignment, material and plating specifications.
The component is confirmed as a double ended pogo pin, but the exact internal spring architecture and movement relationship between the two ends should be confirmed from the approved product drawing.
Working stroke is defined by the approved project drawing and should be distinguished from total mechanical travel. For a double ended contact, the usable movement of each end should be confirmed separately.
Current capability is project-specific and must be validated across the complete conductive path. Tip shape or pogo pin diameter alone is not sufficient to establish the current rating.
It can be assigned to a signal function, but supported data rate depends on the complete channel including return path, contact geometry, adjacent contacts and PCB transitions.
A stepped mechanical feature is visible, but its exact positioning or retention function must be confirmed from the approved drawing rather than inferred from appearance.

This product page presents a CTP pogo pin 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.
The development route depends on whether an existing pogo pin can be used, modified or assembled into a customized multi-contact connector.
