Kyowa KFNB 350Ωsingle axis KFNB Non-Inductive Foil Strain Gauge
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Product name: KFNB 350Ωsingle axis KFNB Non-Inductive Foil Strain Gauge
The special alloy used to make the gauge element minimizes the magnetoresistant effect, and the design of its shape effectively eliminates induction.
Consequently, due to their specialized design, the KFNB series foil strain gauges enable precise strain measurement, even in environments with AC magnetic fields.

Contents
When placing an order, make sure to append the lead-wire cable code to the model number, separating them with a space.
E.g.
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 you do not suffix a lead-wire cable code, we will deliver the gauge with two 10 cm long polyester-coated copper wires.
