The TE 440133-2 is a 2-position, single-row receptacle housing from the High Performance Interconnect (HPI) series. The natural PA66 (Nylon 6/6) body suits general-purpose internal wiring where a UL94 V-2 or V-0 flame rating is not explicitly required by the application. This is the smallest position count in the HPI receptacle family — a 2-circuit housing is the typical choice for a single power pair, a sensor loop, or a low-current signal return path in a harness assembly.
You must order the matching crimp socket separately. The HPI series uses a standard crimp contact that accepts a specific wire gauge range; sectioning a sample crimp to confirm strand capture and pull-out force is routine practice before committing to a production run. The PA66 housing provides the dielectric isolation and mechanical alignment for the mated pair, but the current rating and cycle life are set entirely by the contact and its crimp quality.
