Contents

Besides the silver-clad copper lead wire, KFGS strain gages with pre-attached lead cables are available on request.
When ordering, please suffix the lead-wire cable code to the model number with a space in between.

e.g.
KFGS-30-120-C1-11 suffixes L1M3R for the gage with a 1 m long vinyl-coated flat 3-wire cable becomes
KFGS-30-120-C1-11 L1M3R
