M52-5054645

Headers, Receptacles, Female Sockets Overview

The Harwin M52-5054645 is a vertical socket connector from the Archer M52 series, designed for board-to-board applications. It features 46 positions with a 1.27mm (0.050 inch) pitch and utilizes through-hole termination. The contacts are gold-plated phosphor bronze sockets, housed in black polyamide insulation rated UL94 V-0. Rated for 1A current and 500V voltage, it operates between -40°C and +105°C. The assembly has an insulation height of 8.5mm and a stacking height of 8.37mm.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix code to confirm the exact stacking height and contact length variant, as these parameters define mechanical compatibility. Ensure the procurement channel provides valid RoHS compliance documentation consistent with the manufacturer's current specifications. Cross-reference the part number against official distributor catalogs to confirm active status and avoid obsolete stock.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-pin-count, low-profile vertical connection is required. The 1.27mm pitch allows for dense routing while maintaining electrical isolation. Verify that the mating header matches the specified 8.5mm insulation height to ensure proper engagement depth and mechanical stability within the assembly constraints.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin Archer M52 family, known for compact board-to-board solutions. The M52 series offers various pin counts and heights, providing flexibility for space-constrained designs. This specific model represents a high-density option within the vertical socket category, suitable for complex multi-layer PCB architectures requiring robust connectivity.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible mating headers include M52-040023V2045 and M52-040000P2045 variants with matching 1.27mm pitch. Ensure substitute parts maintain identical 46-position count and vertical orientation to preserve mechanical fit and electrical performance without redesigning the host board.
