The latest addition to Gradconn’s SIM Card Connector family reflects this. CH03-KA, Gradconn’s smallest SIM product, is ideal when space is at a premium, for example hand held devices or wearable mobile products. The Nano SIM connector is a 6 contact, push-pull connector that measures 12.3mm x 10.0mm with a 1.55mm 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 12.3mm x 8.8mm. Nano SIM cards are also thinner than Micro & Mini SIM at 0.67mm vs. 0.76mm.The size reduction has been achieved by making the insulator around the contact area smaller. SIM contact arrangements are compatible with the earlier formats.
