*For other lead-wire cable lengths, contact us.
*Notes on pre-attached lead-wire cables
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.
How to order
When ordering, suffix the lead-wire cable code to the model number with a space in between.
E.g.
KFEL-5-120-C1 with a vinyl-coated flat 2-wire cable 10 m long pre-attached
→ KFEL-5-120-C1 L10M2R
KFEL-5-120-D35 with a vinyl-coated flat 3-wire cable 5 m long pre-attached
→ KFEL-5-120-D35 L5M3S
If no lead-wire cable code is suffixed, the gage is delivered with gage leads only.
(Silver-covered copper wires 25 mm long)
