TE Dynamic D-3200 3-Position Plug Housing — 5.08 mm Pitch
The TE Connectivity 1-179552-3 is a 3-position plug housing from the Dynamic D-3200 series, designed for wire-to-board power and signal interconnects where a 5.08 mm pitch provides adequate creepage for moderate voltage levels. A polarizing key on the housing ensures the plug can only be mated one way to the matching header, which prevents mis-wiring in harness assembly or field service.
With 3 positions, this housing fits harnesses that need exactly three circuits: a power-and-return plus a sense line, or a three-phase motor lead.
Polarizing Key and Crimp Termination — Field-Service Considerations
The polarizing key is a molded feature on the housing that aligns with a corresponding slot on the mating header — it's not a removable insert, so the keying is fixed at the factory. For a field-service technician, this means you cannot re-key the connector if the harness is built for a specific header orientation; verify the key position matches your header before crimping the terminals. The crimp termination requires a separate male pin contact (not included) — typical Dynamic D-3200 pin contacts are ordered as a line item and crimped with a standard open-barrel tool.
