Latest SIM card connectors satisfy the needs of the smallest devices

Communication is making the world ever 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 trend. The new CH03-KA, GradConn’s smallest SIM product, is ideal when space is at a premium, for example handheld devices or wearable mobile products. The Nano SIM connector is a six-contact, push-pull connector that measures just 12.3mm x 10mm with a 1.55mm profile. It is rated for 1,500 card insertion cycles and has an operating temperature range of -40C to +85C. Accurate PCB placement is achieved via the locating pegs. Hold downs offer PCB retention strength. The 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 and 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, says the company.
