DIN Contacts
DIN contacts can be fitted to types L, M
and N male and female housings. These
housings have 3 or 6 4.8 [.189] diame-
ter cavities for high current, coaxial or
fiber optic contacts conforming to DIN
41626.
Male housings are press fit polarized to
backplanes.
Contacts for these housings are shown
on pages 38 and 39.
Standard Type M housings have option
A contacts loaded in columns a to e,
with option C used in rows z and f of
5+2 row versions. Feedthrough pins are
option K. Other arrangements can be
provided; refer to page 47 for other con-
tact patterns. Variations not listed should
be specified using the pin specifications
on page 66 and chart on page 71.
Performance Data pages 6-7, also
refer to DIN specifications.
