SERIES 125/126 AND 165/166 - RETAINERS
Calmark offers the Series 125/126 Card
Retainer as the economical approach to
protecting your Printed Circuit Board in
shock and vibration applications. For
those applications that require shock
and vibration protection and heat
sinking and grounding, the Series
165/166 may be the answer to your
problem. The Series 125/126 is made
from rugged stainless steel while the
Series 165/166 is made from Alloy 10
BeCu for exceptional thermal and
electrical conductivity. These Retainers
conform to DSCC 85034.

Mounting holes are offset
from card path and occur
every inch, offering a
choice of mounting patterns
Independent
sections maximize
contact with
printed circuit card
Turned in tabs and
rigid wall limit card
excursion under
dynamic loading
Spring fingers hold
card against rigid
side providing
dampening under
shock and vibration
Coined edges allow
smooth insertion
and extraction
without damage
to card
