2mm Pitch Miniature Connector for HDD
A3E Series
s
Features
1. Variation in Number of Contacts
This connector can be chosen according to applications, using
together with other series products as follows:
(1) Cable crimping type (A3B series)
(2) Cable ID type (A3E series)
(3) FFC connection type (MA18 series, A3C series)
(However, the A3E series pin header corresponds to the A3E
series socket only.)
On the other hand, 44 contacts are available for AT bus
connection, and 55 contacts for SCSI connection.
2. Batch Insulation Displacement
1 mm pitch ribbon cable can be insulated and displaced.
3. Mechanism to Prevent Mis-insertion
The connector on the socket side contains a mechanism to
prevent mis-insertion in the connector on the header side.
