Gradconn’s Nano SIM Card Connector
A growing demand for smaller and lighter electronic devices drove the development of Gradconn’s Nano SIM card connector.
Gradconn has expanded its SIM Card Connector family with the CH03-KA. 
, such as handheld devices or wearable mobile products. The Nano SIM card connector is a six-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°C to +85°C. Accurate PCB placement is achieved via the locating pegs, while 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.
