Introduction:
The S4EX SIM Extender is a test and signal detection tool for SIM card. It allows a SIMcard to be extended from the host slot for full access to the all of signal pins.
It’s especially designed to save valuable labor and time in the production environment. The S4EX is designed to minimize the signal degradation effects of the extender by proven design techniques. Separate Vcc and ground planes provide a low inductance path to the host’s power supply.
The SIM (Subscriber Identity Module) extender has the function of over-current protection with PTC fuse. A clearly marked jumper header allows probing of all of signal pins. It’s also a powerful tool for engineers, or use for factory test protection. |
