2mm Pitch Miniature Connector

HIROSE ELECTRIC 

C10

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

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.
