Communication really is making the world smaller. The ever expanding demand for mobile connectivity combined with the desire for smaller lighter devices has led to a number of developments in both mobile devices and SIM cards themselves.
The latest addition to Gradconn’s SIM Card Connector family reflects this. CH03-KB, our smallest SIM product, is ideal when space is at a premium, for example hand held devices or wearable mobile products. Our Nano SIM connector is a 6 contact, push-pull connector that measures 12.2mm x 10.8mm with a 1.35mm 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-KB 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.
