6-wire standard cable, up to 0.5mm² stranded wire, with
max. 250nF/km, 750µH/km and minimum 34ohm/km has
22µH/ohm. However, the length of the cable (flexibly
installed) is limited to under 25m by the RS-232
specifications. 6-wire cable, type PR6136 (Lmax =
1.1mH/km; Cmax = 220nF/km; Rmin = 26 ohms/km:
43µH/ohm): under 25m (see above).
