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.
