Kyowa KFRS120Ωsingle axis Foil strain gauge for KFRS printed circuit board
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
PCB are used for varieties of products including cellular phones, car navigation systems and digital cameras.
The gages are the self-temperature-compensation gages (SELCOM gages) for evaluating them.
Features
∙ Dimensions of gage base (bondable space to mounted components and narrow parts)
1.2 mm long by 1.1 mm wide (uniaxial), 2.5 mm long by 2.5 mm wide (biaxial or triaxial)
∙ Linear expansion coefficient of 13 x 10-6/ºC, suitable for component-mounted board
∙ Self-temperature-compensation range is made as wide as –30 to 120ºC to satisfy thermal cyclic tests of PCB.

When ordering, suffix the lead-wire cable code to the model number with a space in between.
E.g.
For the gage with 3 polyester-coated copper wires 10-cm long pre-attached
→ KFRS-02-120-C1-13 N10C3
For the gage with a vinyl-coated flat 3-wire cable 5 m long pre-attached
→ KFRS-05-120-D35-13 L5M3S
