Defines the SIM card type accepted by the connector. SIM Connectors are available in the following form factors (FF):
- SIM (aka Mini SIM) (2FF)
- Micro SIM (3FF)
- Nano SIM (4FF)
Depending on form factor SIM cards vary in size and thickness, although the contact position layout remains uniform across the card types.
SIM connectors are available in the following styles:
- Push-Push -the SIM card is pushed into place and pushed again to release, ejecting by spring action. Push-Push is often used in consumer applications where users insert and eject SIM cards into a device.
- Push-Pull -the SIM card is pushed into place and held in place by force of contacts and pulled to remove. Push-Pull is the lowest cost type of SIM connector.
- Hinged - the connector opens to allow insertion of SIM card, hinged types are useful where a positive lock is required, especially in high vibration environments.
SIM5060 & 5055 hold the card in place in the hinged cover, for ease of use. To achieve an ultra-low profile, the SIM5051 does not hold the card in place.
- Dual - Allows two SIM cards to be plugged into one connector. This is a Push-Pull connector type.
Card Detection Switch
Connectors with a SIM card detection switch enable the designer to electronically signal when SIM cards are inserted or removed. Switches are normally open, the circuit is closed when the card is inserted.
Note – Card detection switches are some sometimes referred to as extra contacts. For example: 6+2 (6 x SIM contacts + 2 x switch contacts).
GCT do not classify card detection contacts as +2, but as ‘with’ or without’ card detection switch.
The height profile of SIM connectors above the PCB. For hinged connectors, profile denotes the connector in closed position.
Plastic locating pegs used to hold the connector in place during solder process and may provide extra strength post soldering. Also known as plastic post.
