Product details

Knife terminal for 14-16 AWG

The 31943 is a non-insulated knife terminal in the Diamond Grip series, accepting 14-16 AWG wire with an insulation diameter range of 0.105" to 0.150" (2.67mm to 3.81mm). The tin-plated copper contact delivers a 0.794" (20.17mm) overall length and a mating stack height of 0.203" (5.16mm).

Position within the Diamond Grip range

Within the Diamond Grip series, the 31943 (14-16 AWG, 0.794" length) sits alongside the 31770 (16-22 AWG, 0.810" length) and the 31763 (14-16 AWG, 0.745" length) — all share the same 0.203" mating stack height and non-insulated construction, so the selection narrows to wire gauge and overall length.

Frequently asked questions

Will 31943 drop into a panel that was specified around 31770 without rewiring?

The 31943 accepts 14-16 AWG wire with an insulation diameter up to 0.150", while the 31770 accepts 16-22 AWG with a maximum insulation diameter of 0.125". The mating stack height is identical at 0.203", but the wire gauge range differs — confirm the wire size before substituting.
