1.27mm Pitch 8Byte DIMM Socket
SX4 Series
■Features
1. 8Byte DIMM Compliant Socket
The SX4 series are a socket compliant to "8Byte DIMM" standardized
at JEDEC.
2. JEDEC Standard MO-161
The applicable module board 1.27mm pitch 168 pos. for double-sided
connection.
3. Easy PC Board Pattern Design
The lead length for soldering dip connection on the board is 1.27mm,
row-row 1.27mm, 1.6mm, 1.905mm, and staggered alignment in 4
rows.
4. Compatible with 5V and 3.3V Operating Voltage Module
Board
5. Prevents Mis-insertion in Module Board
The key mechanism prevents mis-insertion in the module board.
6. Prevents Displacement of Module Board
The structure to sustain the module board on both sides prevents
displacement of the module board.
7. Easy Insertion and Extraction of Module Board
The unique ejector mechanism facilitates to remove the module board. with
pushing the injector.
7. In addition, marginal space is not needed for insertion and extraction actions.
■Applications
Workstations, computers, personal computers, PPC, business machines, measuring instruments, etc.
