Three-Position Plug Housing for the Dynamic D-5200 Series
It accepts male pin contacts (ordered separately) and uses a 0.400" (10.16mm) pitch, giving each circuit generous spacing for higher-voltage or larger-gauge wire applications. A built-in polarizing key prevents mis-mating with the wrong receptacle, which is useful in multi-connector harness assemblies where several D-5200 connectors sit close together.
The 10.16mm pitch is wide enough that the connector can handle the full current rating of the D-5200 contact system without thermal derating concerns in most industrial environments. The TE part number for the compatible contact is typically a 1-xxxxxx-x series Dynamic D-5200 pin terminal; confirm the wire gauge range (commonly 14-18 AWG for this series) against your harness build before placing the full BOM.
The 1-353046-3 adds a third position and a polarizing key instead of sealing — choose the 1-1703532-1 if the application requires an IP-rated mate and you only need 2 circuits; stay with the 1-353046-3 for 3-circuit unsealed harnesses where keying prevents cross-mating.
