Individual Pogo Pin
A single spring-loaded contact supplied for integration into the customer’s PCB, housing or connector structure.
Browse Individual Pogo Pins →
An individual double ended pogo pin featuring an extended plunger on one side and a shorter contact interface on the opposite end. The unequal contact-end geometry can be evaluated for customer-defined compression interfaces where mechanical stack-up or mating depth requires different contact reach on each side. Final stroke, spring force, dimensions, retention method 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 long plunger double ended pogo pin is an individual spring-loaded electrical contact with contact interfaces at both ends. One side has a visibly extended plunger while the opposite side uses a shorter contact geometry.
The unequal contact-end geometry can be evaluated for customer-defined compression interfaces where the two mating surfaces have different mechanical depths or stack-up conditions. The exact purpose of the extended plunger, however, should be confirmed by the approved mechanical drawing.
Although the component has two contact ends, it remains one electrical contact component rather than a two-pin connector. Final dimensions, stroke, spring force, retention method, materials and electrical capability are project-specific.
The visible structure consists of a straight cylindrical body with an extended narrow contact end on one side and a shorter rounded contact end on the opposite side.
Product Type Individual double ended pogo pin
Extended End Long plunger visible on one side
Opposite End Shorter contact interface
Electrical Contacts One electrical contact component
A longer plunger can be evaluated when one mating surface is positioned deeper within a housing or when the mechanical stack-up requires additional contact reach on one side of the interface.
The visible geometry alone does not define the installed position or retention method. The surrounding housing, fixture or mechanical structure should establish the component location and final mating position.
Mechanical datums, guides and stops should control final seating. The pogo pin should provide electrical contact and controlled axial compliance rather than acting as the primary structural stop.
Working stroke and total travel are different mechanical parameters and should be defined separately for the approved contact structure.
For this double ended architecture, engineers should confirm the permitted movement at each contact end, the installed height, mating stack-up, preload condition and mechanical tolerance of the complete assembly.
It should not be assumed that both ends have the same working stroke or that the visible long plunger has a greater usable stroke. The internal spring construction and approved drawing determine the actual operating range.
The longer plunger does not by itself indicate higher current capability. Electrical performance must be evaluated across the complete conductive path.

Depending on the system architecture, PCB traces, solder joints, FPC, wire, connectors or additional interfaces may also contribute to total path resistance.
Vdrop = I × Rpath
Ploss = I² × Rpath
Current capability should therefore be reviewed using contact resistance, complete-path resistance, temperature rise, mating condition and the intended duty cycle rather than pogo pin diameter or plunger length alone.
The contact may be assigned to power, ground, control or signal functions according to the system design. Pin geometry alone does not define data bandwidth.
For signal applications, the complete channel should be reviewed, including contact geometry, return path, adjacent contacts, pitch, PCB transitions and any connected FPC or cable structure.

This long plunger double ended pogo pin can be evaluated when the mechanical interface requires spring-loaded electrical contact on two sides and different contact reach between the two mating surfaces.
Suitability depends on installed height, mating depth, alignment, working stroke, spring force, electrical load and the surrounding mechanical structure.

The visible long-plunger architecture can be evaluated against the customer’s mechanical stack-up rather than selected only by overall appearance.
Depending on engineering feasibility, the approved project drawing can define overall length, barrel diameter, plunger geometry, mating reach, working stroke, spring characteristics, retention structure, materials and surface finish requirements.
For projects with multiple pogo pin contacts, contact pitch, housing structure, mechanical alignment and the complete electrical path should be reviewed together rather than treating each individual contact independently.
It is an individual spring-loaded electrical contact with contact interfaces at both ends and a visibly extended plunger on one side. The extended geometry can be evaluated for customer-defined mechanical stack-ups requiring different contact reach on each side.
No. It has two contact ends but remains one electrical contact component. It is not equivalent to a two-pin connector with two separate electrical circuits.
The unequal end geometry may be useful when the two mating surfaces have different depths or mechanical stack-up conditions. The exact function of the extended plunger should be confirmed from the approved project drawing.
The product is confirmed as a double ended pogo pin, but the exact internal spring arrangement and movement relationship between the two contact ends require confirmation from the product drawing.
No current capability should be inferred from plunger length or diameter alone. Current must be evaluated across the complete conductive path, including both mating interfaces and the connected PCB or module.
The working stroke of each contact end should be defined by the approved drawing and must be distinguished from total mechanical travel.
It can be evaluated for board-to-board or board-to-module compression interfaces when the surrounding mechanical structure controls alignment, installed height and final seating.
A double ended pogo pin can be assigned to a signal function, but supported data rate depends on the complete channel including return path, contact geometry, PCB transitions and adjacent conductors.

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.
