4 Key Points for Pogopin Selection! Avoid Low-Price Misunderstandings and Eliminate Poor Contact Issues

Many enterprises tend to fall into the misunderstanding of “only focusing on price” when purchasing Pogopin, which leads to problems such as poor contact and shortened service life in the later stage. Master the following 4 key selection points to easily choose a suitable product:

Clarify Core Requirement Parameters
Current-carrying Capacity: Select based on equipment power (conventional range: 0.5A-5A; up to 10A or more for special scenarios).
Stroke Range: Choose according to the equipment assembly gap (common range: 0.2mm-3mm).

Pay Attention to Material and Craftsmanship
Needle Material: Tungsten steel and stainless steel are preferred (high wear resistance); the surface gold plating thickness should be ≥0.8μm (to improve conductivity).
Spring Material: Piano wire (excellent fatigue resistance and long service life).

Avoid Common Misunderstandings
Do not ignore sample testing: Before purchasing, it is essential to conduct tests on service life, conductivity, and environmental adaptability.
Do not overlook delivery cycles: Prioritize manufacturers with sufficient production capacity and stable delivery schedules.
