When ordering, suffix the lead-wire cable code to the model number with a space in between.
E.g.
KFP-5-120-C1-65 with 3 polyester-coated copper wires 10 cm long pre-attached
→ KFP-5-120-C1-65 N10C3
If no lead-wire cable code is suffixed, the gage is delivered with gage leads only.
(Silver-covered copper wires 25 mm long)
