NOTES:
•
The length of exposed wir
es is important. The ideal length is 3/16 inch (5 mm).
•
If the stripped section of wir
e is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit.
•
If the stripped section of wir
e is shorter than 3/16 inch, wires can be easily
pulled out even if tightly fastened by the captive screws.
• Do not tin the power supply leads before installing them in the connector. Tinned
wires are not as secure in the connector and could be pulled out.
An unbalanced stereo audio connector consists of a tip, ring,

from existing audio cables, see the image on the right to
identify the tip, ring, and sleeve parts of the connector. The
ring, tip, and sleeve wires are also shown on the captive screw
audio connector diagrams (see figure11, figure12, and
figure13 on page20).
