Microminiature Circular - .050" Contact Spacing
MICRO-K microminature circular connectors are
rugged yet lightweight - and meet or exceed the
applicable requirements of MIL-C-83513. Applica-
tions include computres, biomedical, instrumenta-
tion and miniature black boxes.
MIK:
Accommodate up to 55 contacts on
.050 (1.27) centers (equivalnet to 420 contacts per
square inch). Five keyway polarization prevents
cross plugging. The threaded coupling nuts provide
strong, reliable coupling. MIK receptacles can be
either front or back panel mounted; in back mount-
ing applications, panel thickness of up to 3/32"
can be used on the larger sizes. Maximum termper-
ature range - 55˚C to + 105˚C.
Standard MIK connectors are available in two shell
sizes accommodating two contact arrangements
pre-wired to your specific requirements.
MIKM:
Similar to our MIK, except has a steel shell
and receptacle for improved ruggedness and RFI
resistance. It accommodates up to 85 twist pin
contacts. Maximum temperature range - 55˚C to
+ 105˚ C.
MIKQ:
A quick disconnect metal shell and recepta-
cle version that can be instantaneously disconnect-
ed yet provides a solid lock when engaged. Applica-
tions include commercial TV cameras, portable
MICRO-K
radios, military gun sights, airborne landing systems
and medical equipment. Maximum temperature
range - 55˚C to +125˚C.
MIKQP (All Plastic):
A ligthweight, low-cost,
all-plastic version of the MIKQ connector. The
MIKQP design withstands the corrosive effects of
soil, alkaline and chemicals commonly found in
military, industrial and medical environments. It
also has been ruggedized for use in impact applica-
tions.
For other variations of the basic MIK circular
design, contact your nearest ITT Cannon field sales
office or call our Microminiature Products Group.
