PCN-21-P-CK(A)

` 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)
` 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 50o and a 75o straight jack as well as a right angle 50o jack.
  The daughter card side allows  both a 50o and a 75o straight plug as well as a right angle 50o board mounted jack.
` 50o type and 75o type
  Hirose's unique technology assures that the high frequency characteristics of the 50o impedance type (P051M) and 75o 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.
