It is a dual-row, 4.20mm-pitch housing designed for wire-to-board or wire-to-wire harness applications where a compact, polarized interconnect is needed. The housing accepts female socket crimp terminals (sold separately) and is available in either black or red. The 4.20mm pitch and row spacing are identical, giving a 4.20mm x 4.20mm grid that mates with standard MR-series pin headers. ## Panel Mount and Termination This housing mounts to a panel via snap-in features — no hardware required. The panel cutout must match the housing's snap-in geometry (refer to the product drawing for the exact hole dimensions). The crimp termination style means you attach the contacts to the wire ends first, then insert them into the housing; the locking ramp secures the mated connector pair. The insulation material carries a standard UL94 V-2 or V-0 rating (check the specific color variant). ## Procurement and Lifecycle A common procurement trap: the housing ships without contacts. The buyer must order the matching female socket crimp terminals separately — typically the TE 640550 series or equivalent. Confirm the wire gauge range and crimp tooling before committing the BOM line.","metaTitle":"TE MR 1-640520-0 Plug Housing, 6 Pos, 4.20mm","metaDescription":"TE Connectivity MR series 6-position plug housing, 4.20mm pitch, locking ramp.
