Spring Force - extension refers to the
coiled section < 20N @ 2x extension (T > 10°C/50°F)
< 50N @ 2x extension (T > –10°C/14°F)
< 30N @ 3x extension (T > 10°C/50°F)
Minimum Cable Bend Radius
Flexing values for (T > –10°C/14°F)
20 mm / 0.8 inch - fixed installation
30 mm / 1.2 inch - occasional flexing
50 mm / 2 inch - frequent flexing
Operating Temperature
(ambient, fixed installation)
–25°C to +50°C
–13°F to +122°F
Cable Temperature Rating 80°C / 176°F (internal operating temp)
Warnings:
1. Do not extend the spring coils below 0°C. Do not extend the coils
farther than 2x compressed length below 10°C, or 3x compressed
length above 10°C. Avoid extension above 3x compressed length
because this can cause a permanent stretching of the coil.
2. Make sure that no spring force is applied to the DX BUS connector;
fasten a strain relief or cable tie on or near to the coiled section of
the cable.
