Special order only; contact Switchcraft. |
| 1 |
Many jacks are offered with MIL specifications. Other
jacks
are made of MIL-spec materials but do not have MIL approval
because no MIL type numbers have been assigned. |
| 2 |
MT-Jax have nickel-plated copper alloy bushing. WEco
equivalent jacks
have plain copper alloy bushings (except WEco Number 221E, which has
nickel-plated copper alloy bushing). |
| 3 |
Mating plugs and patch cords are contained in the
catalog. |
| 7 |
Same as MIL type M641/2-3 except with offset ground lug. |
| 8 |
Same as MIL type M641/3-1 except with offset ground lug. |
| 9 |
Same as MIL type M641/3-2 except with offset ground lug. |
| 10 |
When mounted on "A" frames, stacks are too high
to fit in standard
panels with .625 inches horizontal space add prefix "C" to
part number
to order jacks with "C" frame. |
