3.96mm and 4mm Pitch Card Edge Connector
CR7 Series
Connection Type
Eyelet
Through hole
■Features
3. Connection Type
1. Contact Type
Eyelet and through hole types are available.
Uses 2 steps of bellows type
contact, where the contact
4. Prevents mis-insertion in the board
pitch is 3.96mm or 4mm.
Using the polarizing key prevents mis-insertion in the
printed board.
2. Variation in number of contacts
12, 20, 28, 30, 36, 44, 56, 72 and 80 contacts are
available.
