SIM Family

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.

Connector Style

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.

Number of Contacts

Defines number of contacts connecting with SIM card pads.
6 contact versions are most popular as used in the majority of GSM or CDMA applications.

SIM contacts no. 4 and 8 are not generally used and defined by the ETSI spec as ‘reserved for future use’. Although 8 contact versions are used in MegaSIM applications.

SIM Card detection switch contacts are covered in a separate search.

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.

Profile

The height profile of SIM connectors above the PCB. For hinged connectors, profile denotes the connector in closed position.

Locating Peg

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.

Hinged SIM Card Connector

Hinged SIM connector are suitable for Mini SIM cards, the hinged style is often used in applications where customers require the SIM card locked in place and not accessible to the end consumer/user.

GCT's range of three products is surface mount, with profiles above the PCB of between 1.80mm - 2.60mm. All parts are fully RoHS compliant and suitable for operating temperatures of -40°C to +85°C.

SIM5060 offers an economical option for 6 or 8 contacts with an optional plastic locating peg, while SIM5055 & 5051 are available in 6 contacts without a locating peg.

If a SIM card detection switch is required customers should choose SIM5055, this allows the electronic detection of the card when inserted or removed. In this case the switch position is normally open.

Both SIM5055 & 5060 hold the card in place while the lid is being closed, which is helpful for operators. For low profile applications SIM5051 allows the card to be placed direct onto the contacts, the hinged lid then closes and is locked into place. This design allows a 1.80mm profile above the printed circuit board.

SIM5055 offers a robust locking frame which is perfect for high vibration environments where the card must stay locked in place.
