Retractile/Coil Cord Terms
Coil Inside Diameter
The straight, uncoiled sections of the retractile cord, located at each end. Tangents can either be Parallel to the coil or Drop 90 degree angle to the coil; this would be a Parallel Tangent.
The inside diameter of the
coiled section.
18 18 41/34
16 16 65/34
14 14 41/30
12 12 65/30
10 10 105/30
8 8 133/29
Retracted Section
The helical or coiled section of the product (coiled body length when relaxed).
Drop Tangent Configuration
The straight, uncoiled sections of the retractile cord, located at each end. Tangents can either be Parallel to the coil or Drop 90 degree angle to the coil; this would be a 90 Degree Drop Tangent.
Extended (Working) Length
The maximum distance that the retractile will extend to (stretched out length).
Retractile/Coil Body Diameter
The outside diameter of the retracted/coiled section.
Parallel Tangent Configuration
Stranding
Strand Configurations: When selecting the AWG and strands of the individual conductors, it is important to use flex type stranding. These are strand configurations that utilize multiple strands of fine wire, for flex life and flexibility.
Here are some "Rules of Thumb" to consider:
WIRE AWG/MINIMUM STRAND CONFIGURATION
32 32 19/44
30 30 19/42
28 28 19/40
26 26 19/38
24 24 19/36
22 22 19/34
20 20 19/32
