2mm Pitch Miniature Connector
A3 • A4 Series
■Features
1. Miniature Type and High Density Mounting
These connectors are designed in a miniature and light
weight product, and mounted in the high density. The
crimping case is structured in the 2mm pitch grid, so that
connectors can be arranged for use.
2. Variation in Number of Contacts
Dec.1.2018 Copyright 2018 HIROSE ELECTRIC CO., LTD. All Rights Reserved.
In addition to the dip type, SMT and crimping types are
available with broad variations.
3. Stacking Variation
When the connector is used for board to board, set 6mm
between boards in conjunction with the pin header A3B,
or 5.1mm between boards in conjunction with the pin
header A3C.
