Non-inductive Foil Strain Gages
The gage element is made of a special alloy which provides less magnetoresistant effect; also, the shape is designed to eliminate induction. Thus, the KFNB series foil strain gages allow the strain to be measured accurately under AC magnetic environments.

When ordering, suffix the lead-wire cable code to the model number with a space in between.
KFNB-5-350-C9-11 with a vinyl-coated normal-temperature low-noise 3-wire cable 5 m long pre-attached
→ KFNB-5-350-C9-11 J5M3
If no lead-wire cable code is suffixed, the gage is delivered with 2 polyester-coated copper wires 10 cm long each.
