(Light Emitting Diodes) - LEDs
are available in a wide variety of sizes and shapes on RJ
Connectors. The 'standard' LED has a round cross-section
of 5mm diameter and this is probably the best type for general
use, but 3mm round LEDs are also popular. Round cross-section
LEDs are frequently used and they are very easy to install
on boxes by drilling a hole of the LED diameter, adding a
spot of glue will help to hold the LED if necessary. LED clips
are also available to secure LEDs in holes. Other cross-section
shapes include square, rectangular and triangular.
Polarity - For LEDs to be connected the correct way,
the diagram may be labelled or + for anode and k or - for
cathode (yes, it really is k, not c, for cathode!). The cathode
is the short lead and there may be a slight flat on the body
of round LEDs. If you can see inside the LED the cathode is
the larger electrode. LED
Polarity Testing - LED's have a positive side and
a negative side, and will only light up when wired correctly.
Most LED's have one longer lead to indicate the polarity.
