Product Features
Shielded
Keyed
Inverted
A metal shell that provides EMI/RFI
protection. EMI* RFI is unwanted
electromagnetic energy (or “noise”) in the
frequency range that is generally used in
radio communication.
Designed for the use with a keyed plug to
ensure proper mating and will also accept a
standard plug
Contacts are on the bottom and the latch
is on the top to allow for alternate location
of latch.
Inverted Latch

Tab Up
Tab Down
Mounting pegs
Provide location and retention support dur-
ing soldering processes, but do not function
as boardlocks. The majority of modular
jacks have some type of mounting peg.
Grounding Options
LEDs
Panel Ground — Makes contact with the
panel for ground connections
Integrated into the modular jack, eliminating
the need for additional system space for
indicators. Available in multiple colors and
configurations.
PCB Ground — Makes contact with the PCB
for ground connections
Panel Stops
Provides additional mechanical support,
especially with top entry jacks.
*Terminology Key
EMI — Electro Magnetic Interference
RFI — Radio Frequency Interference
