When ordering, suffix the lead-wire cable code to the model number with a space in between.

E.g.
KFGS-30-120-C1-11 With a vinyl-coated flat 3-wire cable 1 m long
→ KFGS-30-120-C1-11 L1M3R

Notes on pre-attached lead-wire cables
● Standard color of the 2-wire cable pre-attached to uniaxial gages is red (R).
If desired, allows a white, green, yellow or black cable to be pre-attached.
● Standard 3-wire cable pre-attached to uniaxial gages has red stripes (R).
If desired, allows the red stripes to be changed to blue or yellow stripes.
● In the case of a biaxial gage and triaxial gage, 2-wire cables are color-coded with red, white and green stripes for 0°, 90° and 45°, respectively and 3-wire cables, with red, yellow and blue stripes for 0°, 90° and 45°, respectively.
The letter code is S in common.
