Hi-D® Jax 2- and 3-CONDUCTOR
Hi-D Jax® 2- and 3-conductor enclosed phone jacks are ideal for panel/chassis and PC board mounting. Unitized molded housing protects springs, provides mechanical and electrical reliability, minimizes leakage and provides low capacity between springs. Mounts on .625 inch minimum centers in rows or arrays. .25 inch or .21 in inside diameter bushing types, metal or thermoplastic bushings (for insulated mounting). Insulated Hi-D Jax^® jacks are specifically designed for in-circuit (insulated) mounting from mounting surface and have fully protected enclosed internal sleeve feature. Solder lugs or PC terminals may be selected.
MOUNTING
Jacks mount in a single .375 inch diameter hole on .625 inch minimum centers. Series 11*, N11*, NS11* and S11* mount in panels up to .156 inch thick. Series L11* and NL11* (long bushing) mount in panels up to .25 inch thick. Jacks with PC terminals mount on PC boards up to .094 inch thick. Formed "shoulders" on each terminal provide stable stand-off mount. Threaded bushing permits mechanical connection to equipment panel. Mounting hardware is supplied.
SERIES 11* - 2- and 3-conductor types, threaded metal
bushing .276 inch long. .25 inch inside diameter
bushings.
SERIES L11* - Same as Series 11*, except bushing is .375
inch long for mounting in panels up to .25 inch thick.
SERIES N11* - Same as Series 11*, except bushing is
molded thermoplastic for insulated mounting.
SERIES NL11* - Same as Series N11*, except bushing
is .375 inch long for insulated mounting in panels up to
.25 inch thick.
SERIES S11* - Same as Series 11*, except bushing has
.21 inch inside diameter. Smaller diameter protects against
accidental insertion of plugs with .25 inch diameter fingers.
ı NS11* - (SPECIAL ORDER ONLY) - Same as
Series N11*, except bushing is .21 inch inside diameter.
113BPC1M AND 114BPC1M - Versatile, 3-conductor 113BPC1M and 114BPC1M feature springs which accept a wide variety of 1/4 inch plug designs. Self-aligning PC terminals allow for easier insertion into a printed circuit board. Also feature a metric thread mounting.
