When ordering, specify the model of the strain gage and the code of the lead-wire cable with a space in between.

E.g.
KFGS-5-120-C1-11 With 2 polyester-coated copper wires 15 cm long
→KFGS-5-120-C1-11 N15C2

KFGS-5-120-C1-11 With a vinyl-coated flat 2-wire cable 5 m long
→KFGS-5-120-C1-11 L5M2R

KFGS-5-120-D17-11 With a vinyl-coated flat 3-wire cable 5 m long
→KFGS-5-120-D17-11 L5M3S

KFGS-5-120-C1-11 With a mid-temperature 3-wire cable 5 m long
→KFGS-5-120-C1-11 R5M3

KFGS-5-120-D17-11 With a mid-temperature 2-wire cable 5 m long
→KFGS-5-120-D17-11 R5M2

If no lead-wire cable code is suffixed, the gage is delivered with gage leads only.
(Silver-covered copper wires 25 mm long)

Remarks

[Notes on pre-attached lead-wire cables]

∙ Standard color of the 2-wire cable pre-attached to uniaxial gages is red (R).
If desired, a white, green, yellow or black cable can be pre-attached.

∙ Standard stripe of the 3-wire cable pre-attached to uniaxial gages is a red stripe.
If desired, allows a blue or yellow stripe to be pre-attached.

∙ 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.
