The LEA Series uses the SFH Series contacts, which are designed to accommodate a wire range of 22 AWG to 30 AWG and are made of tin-plated, phosphor bronze base material. The box construction ensures stable contact performance, redundant contact points, positive electrical contact and low contact resistance at all times even when subjected to vibration and distortion. The suggested wire strip length is 1.7 mm. Crimp heights vary by wire size 0.56 mm (30 AWG) to 0.78 mm (22 AWG).
