sFeatures
1. 72pos. Small Outline DIMM Socket
SX1 series is a 0.635mm pitch horizontal SMT type socket
applicable to
Small Outline DIMM standardized in JEDEC.
The size is about half as large as the conventional 72 contacts
DRAM SIMM socket.
Corresponding to double density (both surfaces), this socket realizes
high functionality and density of the module board.
q
High Profile Type (Mounting Height: 8.0mm)
2. Variation in Mounting Height
Three grades of variation are available for the mounting height.
3. Easy Insertion and Extraction of Module Board
One-touch operation to insert the module board slantly and push it
downward.
Widen latches right and left, and the module board will be
automatically raised.
This mechanism allows easy automatic insertion and extraction.
4. Achieve High Performance
This socket achieves high performance by the wiping effect in the
insertion and the unique press-fit face contact.
Easy Insertion and Extraction Operation of
Module Board
5. Insertion and Extraction Operation with Click
Sensibility
The unique mold twin-latch allows excellent insertion and extraction
operation with a sensible click.
sApplications
Personal computers, business equipment, Measuring instrument,
telecommunication equipment, FA, game, etc.
