2mm Hard Metric Coaxial Connector
PO21M, PO51M, PO82M Series
(IEC 61076-4-101 Compliant)
Photo 1
sSummary
P021M, PO51M, and P082M connector series are a plug-in type
coaxial contact and an applicable housing case compliant with the
2mm hard metric standard (IEC 61076-4-101).

Mounted on the same board as the 2mm
hard metric connector
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.
