To hold the entire module securely, the connector and latch are positioned at either end of the card and operate together to enable module ejection. Both components are surface-mounted and optimised for automated assembly.
The MM60 connector is a 52-way device meeting the PCI-SIG electromechanical specifications for Mini Card. It has low insertion loss of –1dB at 1.25GHz, low return loss of –12dB at 1.7GHz, and low crosstalk of –32dB at 1.25GHz. Other performance characteristics include initial contact resistance below 55mΩ, rated current of 0.5A per pin, and dielectric withstand voltage of 300Vrms for 60 seconds.
The connector features gold-plated contacts, as well as a hold-down with tin-plated surface-mount terminations for lead-free soldering. The stainless steel latch also has tin-plated terminations for lead-free soldering. Insulators are made from UL94V-0 fire-retardant material meeting international safety requirements, and the connector is specified for operation from –40°C to 80°C.
