Q1: Does the performance of a SIM card connector degrade in high or low-temperature environments? What is the temperature range it can withstand?

The reliability of a SIM card connector is directly related to its material system, terminal plating, and the heat resistance level of the plastic. The operating temperature range for standard industrial-grade SIM card connectors is -25°C to +85°C, while automotive or outdoor equipment often requires a range of -40°C to +105°C.

In practical tests, SIM card connectors with LCP high-temperature plastic and phosphor bronze gold-plated terminals showed that after 1000 hours of high-temperature aging, the contact resistance change was controlled within ±5mΩ. Some of MOARCONN's industrial-grade SIM card connectors have passed such thermal cycling tests and are suitable for smart metering and industrial communication modules.
