Features
1. IEC compliant
This 2 mm Hard Metric (HM) Connector complies with
IEC 61076-4-101. As specified by IEC Standards, 3
types are available: Style A (110 contacts), Style B (125
contacts), Style C (55 contacts) and Style M.
2. Many Variations
Products equivalent to Compact PCI standard P2/J2 (110
contacts), P3/J3 (95 contacts) and AB Type (125
contacts) are available.
3. Press-fit connection
Connectors of this series, headers and receptacles, are
designed for press fit connection.
4. Both-side, two-point contact
Receptacles feature two-point contact design for high reliability.
5. Ground Connection Supported
Contacts are lined up in rows z a b c d e f. Five rows (a
b c d e) are used for signals and two rows (z f) can be
added at both sides for use as ground.
6. 3-Stage Sequence Supported
There are 3 types of coupling portion contact lengths for
the header which permits a 3-stage sequence.
7. Coding Keys Can Be Mounted
Coding keys can be attached to style A for the purpose
of preventing incorrect insertion of the connector.
8. Two different platings are available on PCB
leads
Gold plating and Tin plating are available on PCB leads.
