Introduction
Card holders
Card holders
Card holders are used for adapting Euro 19" format
(100 x 160 mm) cards to plug-in connectors acc. to
IEC 603/DIN 41612 and DIN 41617.
Cardholders can be used in industrial applications when:
• Adapting several 19" cards: As well as saving on the cost
of a rack, accessibility is improved, because usually racks
are only accessible from behind.
• The PCB card is in a remote position, making it difficult to
install the cabling.
• It is necessary to extend legacy systems by adding more
electronic modules.
• There are processes where quick replacement of the
printed circuit and easy handling of connections is
important.

Card holders have the following individual components:
• Snap-fit base and mechanism for securing the card
• Assembly plate and feet for direct assembly or for locking
on DIN rails
• Printed circuit board where the following features can
be identified:
– Plug-in connectors acc. IEC 603/DIN 41612 and
DIN 41617
– Weidmüller terminals for screw connection
