2mm Pitch Miniature Connector for HDD A3E Series ■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. type without polarizing guide 3. Mechanism to Prevent Mis-insertion The connector on the socket side contains a mechanism to type with polarizing guide prevent mis-insertion in the connector on the header side. ■Product Specifications Current rating: 0.5A Operating Temperature Range:-55 to +85ç (Note 1) Storage Temperature Range:-10 to +60ç (Note 2) Rating Voltage rating: 125V AC Operating Moisture Range:40 to 80% Storage Humidity Range:40 to 70% (Note 2) Item Specification Condition 1.
