Technical and Performance Data
(Applicable to MCK, MCD and MCDM unless otherwise noted)
MIL-DTL-83513 — Only the descriptive legend in bold italic is applicable to current MIL-DTL-83513 configurations;
MIL-DTL-83513/1 through /4 — MCK metal shell; MIL-DTL-83513/6 through /9 — MCD plastic shell.
In addition, MIL-DTL-83513 solid copper wire termination is specified 25 AWG, 0.5; and 1.0 [25.4] lengths only and
stranded insulated wire termination is specified 26 AWG, 18.0 [457.2] and 36.0 [914.4] lead lengths only. Hardware for
MIL-DTL-83513 configurations is specified separately by the M83513/5-XX designation. M83513/1 through /4 and /6
through /9 specify no hardware (B). Mounting/mating hardware is shown on page 14 with the applicable military
nomenclature. The MICRODOT catalog part number for a MIL-DTL-83513 configuration may be constructed
to include the desired hardware.
See pages 31-35 for M83513/ cross reference.
Twist Pin, Pin and Socket
Contacts
The contact spring member
normally found in socket
contacts has been eliminat-
ed by creating a breathing
helical spring principle on
the pin contact — smaller,
moredurable contacts
can be manufactured
economically.
Wire range 24-36 AWG solid & stranded.
