Q1: What is the typical insertion and removal lifespan of a SIM card connector? Does it affect long-term reliability?

The insertion and removal lifespan of a SIM card connector is primarily determined by the elasticity of the contact material and the thickness of the surface plating. Standard consumer-grade SIM card connectors are typically designed for around 5,000 mating cycles, while industrial-grade versions can exceed 10,000 cycles.

During mating cycle tests, when the gold plating thickness is below 0.3 μm, contact surface wear accelerates significantly, leading to a noticeable increase in contact resistance. To address this, MOARCONN adopts a thickened gold plating design in its high-durability models, ensuring electrical performance remains stable and within industry-accepted limits even after up to 10,000 insertion cycles.
