Snake Cables (Multicore Microphone
Cables)
Mogami multicore cables are designed for the highest level of audio
performance and feature superb electrical and mechanical characteristics
while remaining compact, superflexible and easy to use.
- Individually twisted shielded pairs, available in 2 to 48 channels.
- XLPE (Cross Linked Polyethylene) insulation provides superb electrical
characteristics and will not melt or shrink back during soldering.
- Rugged and flexible construction that is easy to handle, even at temperatures
down to -20°C (-4°F).
- Easy cable identification system:
- Channel numbers are printed and underlined on each core jacket
to ensure correct identification, regardless of which end is stripped.
- Outer jackets of each pair are colour coded by standard resistor
colour code, allowing quick identification of conductor pairs.
- Inner conductors are also colour coded based on the international
standard resistor colour code. Each pair is colour coded by jacket
and conductor colour combination.
- Each channel has a drain wire and served (spiral) bare copper shield.
The drain wire simplify termination and can be crimped by the same size
contact as the inner conductor pair.
- CL2 rated version available. Conductor size of CL2 rated version is
thicker #25AWG so that it is also recommended for rugged application
and firm and easier crimp terminal connector wiring as well as NEC fire
regulation requirement.

- Colour identification is based on the resistor colour code.
- Colours indicated in parenthesis indicate the print colour on the
core jacket.
- Insulation colour of other wire in all pairs is clear.
- Colour of outer cable jacket is black.
- How to read core jacket channel numbers
Each number printed on the core jacket is underlined (as shown below)
in order to prevent mis-reading of cable numbers.

 |
means NINE |
|
3) |
 |
means EIGHTEEN, not EIGHTY-ONE |
