The Micro Line - .050" Contact Spacing
Test Data
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.
Contact rating - 3 amps max.
Contacts centers - .050(1.27).
Wire sizes - #24 thru #32 AWG, stranded or
solid.
Contact termination - multiple indent crimp.
Contact retention -fixed via epoxy.
Contact materials and finish - Copper alloy,
gold-plated per MIL-G-45204, Type II, Grade C,
Class 1 over copper flash.
Mating/unmating force - 8 oz. per contact,
max./0.5 oz. per contact min.
The table below summarizes the results of key tests
performed
in
accordance
with
MIL-STD-1344,
where applicable. Data is applicable to standard
connectors
with
standard
termination.
Variations
may affect this data, so please consult the factory
for further information on your requirements.
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.
