MDM-51PCBRP Datasheet, PDF (1/17 Pages) List of Unclassifed Manufacturers – The Micro Line - .050" Contact Spacing

The Micro Line - .050" Contact Spacing
The Cannon MICRO Series established the stan-
dards for performance and reliability in mircominia-
ture interconnects. Exceptionally versatile, MICRO
connectors are available in rectangular, circular, and
strip configurations, with 3 amp MICROPIN™/
MICROSOCkET™ contacts on .050(1.27) centers,
or with special arrangements of power and coaxial
contacts.
The heart of the Cannon MICROPIN/MICROSOCK-
ET contact system is a multi-element Twist Pin
Contact recessed with and insulating housing. The
rugged, cylindrical sockets are mounted in the
exposed half of the connector. When connector
halves are mated, the chamfered sockets are first
aligned by the connector body, then guide the spiral
MICROPIN contacts into proper and positive align-
ment, even under worst-case tolerance conditions.
This is Cannon's POS-A-LINE connectors design.
The multiple spring elements of the MICROPIN,
then under compression, form a multi-point contact
system of high mechanical and electrical integrity.
Contacts will provide a high degree of reliability
over hundreds of mating and unmating cycles, and
have proven themselves in applications that range
from commercial products to equipment that has
been landed on the moon.
