interlock all parts and tip springs grip mating plugs positively. Mates

with Switchcraft Micro-Plug® phone plugs. Jacks mount through

.190" diameter hole in chassis/panels up to .093" thick. For insulated

mounting, a .281" diameter hole and .050" maximum panel thickness

applies. Order insulating washer separately. Number P1617

(flat phenolic washer) and Number P1618 (swedged fiber washer).

Number TR1PC: 2-conductor closed circuit jack with PC

terminals. Open frame and enclosed versions available. Mates with

terminals. Mounts to single-, double-sided or multilayer boards either

singly or in rows as close as .344" centers (+/- .01 inches). Bushing is

.10" inside diameter.

Number MDSL2A: Same as MDPC2A except, 1. solder lugs, 2.

bushing is #10-48 threaded (nut and washer supplied), and 3. mount

ing centers are .35" or .313". When mounted on .313" centers, sleeves

or adjacent jacks may be in intimate contact. Mounts through a .203"

diameter hole in chassis/panels up to .063" thick.
