  • Dimensions in inches. Unless otherwise specified, tolerances: decimals ±.016.
  • Insert arrangements per MIL-STD-1651. Style P is a pin insert, S a socket insert; W, X, Y or Z marks an alternate insert position (no letter for the normal position).
  • Class A: a socket insert of hard material extends .016 maximum beyond or .032 maximum below the shell; a socket insert of resilient material extends .047 +.000 −.047 beyond the shell. Where resilient inserts are used, JJ may be .109 less than shown.
  • Classes R and F: add .375 to L for size 0 contacts. Packing per MS28900, dash number as listed.
  • Class A was cancelled after 1 Jan 1991 and class E after 1 Jan 1991 (for replacement: MS3106F with clamp, MS3106R with grommet seal). Classes K, R and F are inactive for new design after 1 Jan 1991. For new design: MS3456W with an M85049/31 backshell (classes A, E and R), MS3456 with an M85049/31 backshell (class K), MS3456W with an M85049/52 backshell (class F); for shipboard jacketed cables, MS3406.
  • MS3106A replaces and is interchangeable with AN3106A (or B); MS3106K with AN3106K; MS3106E with AN3106E; MS3106R with MS3106E and AN3106E without saddle type cable clamp; MS3106F with MS3106E and AN3106E with saddle type cable clamps.
