Designed in Miniature 2
Contacts with High
Precision Spring
ꢀFeatures
1. High Reliability
4. Miniature Type and High Density Mounting
This socket achieves high reliability in the horizontal
contact spring system.
The low profile with 6.2mm height from the board is
suitable for miniaturization of equipment. The 1.27mm pitch
between contacts assures mounting with high density.
2. Low Insertion Force
5. Wide Effective Mounting Area
This socket prevents mis-insertion force in the preload
structure.
This socket is capable of widening the effective mounting
area on the module printed board, and secures retention
function by easy locking.
3. Easy Pattern Design
Ø
6. Easy Board Mounting
The dip contact through-hole diameter is only 0.5, and
simplifies the pattern design.
The fixing pins are arranged in the same alignment as the
contact, so as to easily install the connector in the board.
7. Accessories
Dust covers and jigs to remove the board are available.
