FE CONNECTOR
1.25mm pitch/Connectors for FFC
NON-
The FE connector ensures easy, secure
connection of flexible flat cables (FFC).
This compact connector is 4.8mm wide,
7.5mm high, and provides high contact
pressure even though little force is
required for insertion. The result is smooth
insertion and reliable contact performance.
The connector is useful in making
personal computers, VCRs and car stereo
systems smaller and lighter.
