Gradconn's smallest SIM product is suitable when space is at a premium, for example hand held devices or wearable mobile products. The Nano SIM connector is a six-contact, push-pull connector that measures 12.3 x 10.0 mm with a 1.55 mm profile. It’s rated for 1,500 card insertion cycles and has an operating temperature range of -40° to +85°C. Accurate PCB placement is achieved via the locating pegs; hold downs offer PCB retention strength.
CH03-KA is designed for the 4FF Nano SIM card. This format was introduced in 2012 and is currently the smallest SIM available, measuring 12.3 x 8.8 mm. Nano SIM cards are also thinner than Micro & Mini SIM at 0.67 mm vs. 0.76 mm.The size reduction has been achieved by making the insulator around the contact area smaller. SIM contact arrangements are compatible with the earlier formats.
