GCT offer two Nano SIM connectors, both are 6 contact push-pull type measuring 11.00mm x 12.30mm with profile height of 1.35mm. A full metal shell provides heat and EMI resistance, while a card stop function ensures the SIM card is inserted in the correct orientation.
SIM8050 is plated with 15µ” gold and suitable for 5,000 card insertion cycles, while SIM8051 is 3µ” gold plated and suitable for 1,500 card insertions cycles.
Both have an operating temperature of -40°C to +85°C. Optional PCB locating pegs and SMT holdowns provide extra printed circuit board retention.
Nano SIM connectors accept the Nano SIM card format, 4FF (4th form factor) cards measure 12.3mm x 8.8mm x 0.67mm, Nano SIM cards maintains existing standard SIM contact arrangements while reducing the card insulator size. Compared to Micro SIM a smaller area of isolating material remains around the contacts to avoid short circuits.
At 0.67 mm thickness Nano-SIM cards are approximately 15% percent slimmer than Mini/Micro SIM cards at 0.76mm thickness.
