Microminiature Circular - .050" Contact Spacing
MICRO-K microminiature circular connectors
are rugged yet lightweight - and meet or
exceed the applicable requirements of MIL-
DTL-83513. Applications include biomedical,
instrumentation and miniature black boxes.
MIK:
Accommodate up to 55 contacts on .050
(1.27) centers (equivalent to 420 contacts per
square inch). Five keyway polarization prevents
cross plugging. The threaded coupling nuts
provide strong, reliable coupling. MIK recepta-
cles can be either front or back panel mounted;
in back mounting applications, panel thickness
of up to 3/32" can be used on the larger sizes.
Maximum temperature range - 55˚C to + 125˚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 + 125˚ C.
MIKQ:
A quick disconnect metal shell and
receptacle version that can be instantaneously
disconnected yet provides a solid lock when
engaged. Applications 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.
