Ultra-low-profile height of 1.35mm (78723), 1.40mm
(78727 and 78800)
Ideal for ultra-slim smart phone applications
Card polarization features (all series) Ensure correct card orientation when used with socket
Top-loading style socket allowing 180-degree opening
of lid (78800)
Eliminates any possibility of terminal crush as the SIM
card is mounted top-down
Anti-short feature using raised housing walls of
the socket (78723, 78727) and kinked shell design
(78646)
Prevents shorting of any exposed edge of (improperly
pared) SIM card contact pads with the surrounding
metal shell
Integral metal-shell spring tab (78723) Ensures high normal force (0.30N) and good electrical
contact with inserted micro-SIM card
Detect Switch with First-Mate-Last-Break capability
(78727)
Enables detection of micro-SIM card when inserted

Features and Benefits
Hinged and Push-Pull Style Micro-SIM
Card Sockets, Halogen-free, Lead-free
Optimize space savings with highly compact and reliable
hinged and push-pull style micro-SIM card sockets for
ultra-slim mobile devices
Molex has added a 1.40mm height, hinged socket (series 78800) to its
array of push-pull style micro-SIM card interconnects (series 78723, 78727,
78646). This low-profile socket is ideal for ultraslim smartphones with
limited vertical space between SIM socket and the phone battery-cover.
Maximizing space savings and facilitating easy, top-loading of SIM card, the
socket is the designer’s choice for mid-board layouts that preclude the use
of front- or side-entry style sockets. Measuring only 16.96 (L) by 13.69 (W)
by 1.40mm (H), the socket is more compact than competing equivalents.
The socket’s U-shaped metal hinge provides high pulling force between lid
and shell to ensure robust card retention, electrical contact and reliability. A
uniquely designed locking mechanism allows a partial tilt of the lid into lock
position; or full opening at 180-degrees to the horizontal, for easy removal
and placement of SIM card.
Molex’s push-pull style micro-SIM card sockets come with anti-shorting,
card polarization and other features for high user- and electrical reliability.
Integral solder tabs on the socket shells provide robust PCB hold-down
during soldering. Insert-molded LCP housings maintain design and
dimension precisions while sustaining high-temperature operations.
The socket terminals of this family have rounded profiles to facilitate
smooth card insertion and withdrawal. Aligned in reverse direction, the
terminals prevent contact stubbing and allow gradual ‘lead-in’ of the SIM
card when inserted. This unique terminal geometry ensures high contact
integrity and connectivity when mated.
Molex’s hinged and push-pull style sockets come in standard 6-circuit
configuration. Customers can request for 8-circuit push-pull style sockets
if needed. Parts are shipped in tape-on-reel packaging. All Molex micro-SIM
sockets featured in this release are halogen-free, ELV- and RoHS-compliant
for environmental sustainability.
