Comparison and Selection of Barrel Spring and Crown Spring Pogo Pins

Barrel and crown spring pogo pins differ significantly in design, performance, and applications:

1. Structural Design

Barrel Spring

• Uses a single barrel-shaped spring for elasticity, connecting the pin shaft and tube.

• Features single-point or linear contact, with a simple "pin shaft - spring - pin tube" structure.

Crown Spring

• Comprises 3 - 8 radially arranged elastic reeds forming a crown-like shape.

• Offers multi-point annular contact, providing a larger, more even contact area.

2. Performance Comparison

Dimension	Barrel Spring	Crown Spring
Resistance	High (50 - 100mΩ), unstable under vibration	Low (≤20mΩ), vibration-resistant
Current	≤1A, for signals or low currents	≥3A, ideal for power connections
Lifespan	50,000 - 100,000 cycles	Over 500,000 cycles
Environment	Poor dust/water resistance, prone to oxidation	Multi-point design resists oxidation, supports IP67 sealing

3. Application Scenarios

Barrel Spring Use Cases

• Consumer Electronics: Mobile wireless charging, smartwatch interfaces (cost: 0.07 - 0.14/unit).

• Basic Testing: PCB conduction tests with low stability requirements.

Crown Spring Use Cases

• Industrial: Aerospace connectors, medical device chargers (e.g., surgical robots).

• Harsh Environments: Outdoor base station power connectors.

4. Selection Guide

• Low Cost & Low Current: Choose barrel springs (e.g., home appliance remotes).

• High Current & Reliability: Opt for crown springs (e.g., EV batteries), despite higher cost (0.7 - 1.4/unit).
