Five physical contacts can be allocated to power, ground, signals, detection, identification or other project-specific functions. The Pin Map, pitch, working stroke, spring force, termination, mating targets and electrical ratings should be confirmed together in the approved connector drawing.
This product is a complete five-contact connector assembly rather than five independent pogo pins. The molded housing controls contact position and provides an interface for product-level alignment, installation and mechanical support.
This connector contains no magnets. Electrical contact pressure is generated by the internal pogo pin springs, while final alignment and retention must be provided by the housing, product enclosure, locating features, bracket, latch, fasteners or another controlled mechanical structure.
A 5-pin pogo pin connector combines five spring-loaded electrical contacts inside a controlled housing. Each pogo pin normally includes a moving plunger, barrel, internal spring and electrical termination.
During mating, the plungers compress against corresponding conductive target pads or fixed contacts. The springs create contact force, while the connector housing and surrounding device structure control contact alignment and working compression.
| Interface Function | Primary Structure | Engineering Purpose |
|---|---|---|
| Electrical connection | Five spring-loaded contacts | Carry the approved power, ground, signal, detection or identification functions |
| Contact positioning | Molded connector housing | Controls contact layout, pitch and relative position |
| Working compression | Pogo pin stroke and mechanical stop | Keeps every contact within its defined compression range |
| Alignment | Housing surfaces, locating features or device guides | Limits lateral offset, rotation and side loading |
| Retention | Housing, bracket, enclosure, clip, screw or latch | Maintains the connected position without magnetic force |
| Electrical termination | PCB, SMT, DIP, wire, solder cup or FPC structure | Connects the five-contact interface to the device electronics |
The product image confirms a housing-integrated spring-contact connector. Detailed dimensions and electrical parameters should be completed using the actual engineering drawing and test records.

| Example Architecture | Possible Allocation | Primary Engineering Review |
|---|---|---|
| Power plus detection | Two power contacts, two return contacts and one detection contact | Current sharing and power-enable logic |
| Power plus signal pair | Power, ground, two signal contacts and detection | Signal return, PCB routing and complete-channel validation |

| Charging and temperature sensing | Power, return, detection, identification and temperature sensing | Charging logic and sensor-reference path |
| Project-specific interface | Five customer-defined electrical functions | Voltage, current, spacing, sequencing and system logic |
These examples do not define the fixed wiring of this product. The final Pin Map must follow the customer schematic.
| Contact | Project Function | Required Definition |
|---|---|---|
| Pin 1 | Customer-defined | Voltage, current and electrical state during mating |
| Pin 2 | Customer-defined | Power return or signal-reference requirement |
| Pin 3 | Power, signal or sensing | Electrical load and PCB-routing requirement |
| Pin 4 | Signal, detection or control | Signal return and contact sequence |
| Pin 5 | Identification, sensing or project-specific function | System logic and valid-connection recognition |
For every contact, define:
The drawing should clearly identify Pin 1 and the viewing direction.
Define:
Mirrored numbering between the mating side and termination side can cause PCB, wiring and inspection errors. The schematic, connector drawing, PCB footprint and test fixture should use the same orientation convention.
Pogo pins are intended primarily for controlled axial compression. The spring contacts should not be used as the only features responsible for connector alignment or retention.
The integrated housing may be developed with:
The preferred mechanical sequence is:
Housing guidance → connector seating → controlled contact compression → mechanical stop
The housing or device enclosure should absorb lateral force and define the final connector position.
Working stroke is the amount each pogo pin is compressed after the connector reaches its final seated position.
The dimensional stack may include:
| Assembly Condition | Possible Risk | Required Verification |
|---|---|---|
| Minimum compression | Insufficient spring force or intermittent contact | Minimum-force and electrical-stability test |
| Nominal compression | Primary operating state | Force, resistance and connector-function test |
| Maximum compression | Excessive force, housing stress or mechanical bottoming | Maximum-force and remaining-travel review |
| Uneven compression | Different force or resistance across the five contacts | Housing flatness, contact height and target coplanarity |
The complete reaction force is the combined force generated by all five compressed contacts.
Total force depends on:
The housing, PCB, bracket and mechanical stop should be designed for the total connector force rather than the force of one pogo pin.
Current capability must be evaluated through the complete electrical path.
Define:
A rating such as “2A / 5V” is incomplete unless it states whether it applies per contact or to the complete connector and identifies the relevant test conditions.
Multiple contacts may be connected in parallel for power or return, but current should not be assumed to divide equally.
Current sharing can be affected by:
Path-level voltage drop and temperature should be evaluated where parallel contacts carry meaningful current.
Five contacts can be allocated to a combination of power and signal functions, but Pin count does not establish support for USB, UART, I2C, CAN or another protocol.
Signal design should consider:
Protocol compatibility should only be published after the complete connector, PCB and cable or FPC channel has been validated.
Every pogo contact requires a corresponding conductive target pad or fixed mating contact.
The mating side should define:
The connector and mating targets should be developed together rather than designed as unrelated components.
The exact termination of this product should be confirmed from the engineering drawing.
| Termination Option | Possible Integration | Primary Review |
|---|---|---|
| PCB / SMT | Direct board-mounted assembly | Footprint, soldering, coplanarity and housing support |
| Through-hole / DIP | PCB assembly using extended solder tails | Finished holes, installed height and solder process |
| Wire termination | Connector separated from the main PCB | Wire gauge, Pin Map, soldering and strain relief |
| FPC termination | Thin or space-constrained electronic module | Reinforcement, bend radius and strain relief |
| Integrated module | Connector supplied with PCB, housing or cable | Complete product-level dimensional and electrical validation |
A pogo pin connector should not automatically be described as IP54, waterproof or corrosion-resistant based only on its contact finish or housing appearance.
Environmental performance may depend on:
Any IP rating should identify the complete tested assembly and test condition.
Contact-resistance, mating-cycle, plating and salt-spray claims should also state the measurement boundary, working stroke, sample condition, applicable test method and acceptance criteria.
This 5-pin pogo pin connector assembly may be evaluated for:
Application suitability should be confirmed from the actual Pin Map, electrical load, signal requirements, mounting method, working stroke and operating environment.

No. This is a non-magnetic pogo pin connector assembly. Alignment and retention are provided by the housing and surrounding product structure.
The contacts may be allocated to power, ground, signals, sensing, detection, identification or other project-specific functions according to the approved Pin Map.
No. Five Pin describes the number of physical contacts. USB or another protocol requires a suitable Pin Map, signal-return structure, PCB routing, cable and complete-channel validation.
Yes. Separate contacts may be assigned to power, ground and selected signals. The complete current and signal paths must be reviewed together.
Parallel contacts may be evaluated for power or return, but current sharing can be unequal because of contact resistance, compression and PCB-routing variation.
The connector housing, locating features, guide surfaces, bracket or device enclosure should control alignment and final seating.
Environmental protection depends on the complete connector, termination, seals and device enclosure. A universal IP rating should not be assigned without a defined tested assembly.
Current capability depends on the pogo pin construction, working stroke, termination, target contact, conductor size and permitted temperature rise.
Yes. Housing geometry, locating features, contact layout, pitch, stroke, spring force, termination and mating targets can be reviewed according to the project.
