2mm Hard Metric Coaxial Connector

PO21M, PO51M, PO82M Series

(IEC 61076-4-101 Compliant)

NEW

2001.6

sFeatures

1. Profile complies with 2mm hard metric

This connector can be mounted on the same board as the hard

metric connector. (Refer to Photos 1 and 2.) It uses Compact-PCI

designated key options to identify a 3.3V or 5V system.

(Hirose’s MU optical fiber series can also be mounted on the same

board as the 2mm electric system connector. Refer to Photo 1)

2. Flexible Design allows for various terminations

The housing (P021M series) allows for both cable mount as well

as board mounted connectors. The back plane side allows both a

50ø and a 75ø straight jack as well as a right angle 50ø jack.

The daughter card side allows both a 50ø and a 75ø straight

plug as well as a right angle 50ø board mounted jack.

3. 50ø type and 75ø type

Hirose’s unique technology assures that the high frequency

characteristics of the 50ø impedance type (P051M) and 75ø

impedance type (P082M) are consistent between the fully

mated position and a mated position with a 1mm gap.

Note: The P082M connector opening is designed in the HRS original

form in order to enhance high frequency characteristics.
