Ultra-Fit connectors offer characteristics of Mini-Fit and Micro-Fit 3.0 connectors with, but not limited to, additional color-coded housings, optional TPA retainer to reduce terminal backout, and reduced profile up to 20%. For terminating to cable or wire harness assembly, solutions accommodate 2 options: overmolding, which encapsulates terminals with such resin as PVC or TPR, or injection molding, which also integrates strain relief to provide additional flexibility and ruggedness.
