M52-5004045

Headers, Receptacles, Female Sockets Overview

The M52-5004045 is a single-row receptacle connector from the Harwin Archer M52 series, designed for board-to-board applications. It features 40 positions with a 1.27mm (0.050 inch) pitch and utilizes through-hole termination. The contacts are made of phosphor bronze with gold plating, housed in black polyamide insulation rated UL94 V-0. Rated current is 1A, with an operating temperature range of -40°C to 105°C.

Headers, Receptacles, Female Sockets Feature Summary

• High-density single-row architecture supporting up to 40 positions
• Push-pull locking mechanism ensures secure mating retention
• Gold-plated phosphor bronze contacts provide reliable conductivity
• Polyamide housing meets UL94 V-0 flammability standards

Headers, Receptacles, Female Sockets Applications

• Telecommunications equipment interconnects
• Medical device circuit boards
• General industrial control systems

Headers, Receptacles, Female Sockets Procurement Notes

Verify component authenticity against official Harwin documentation before integration. Confirm that the specific suffix indicates the correct pin count and termination style. Ensure compatibility with mating header specifications regarding stacking height and contact geometry. Validate RoHS compliance status for the target production environment.

Headers, Receptacles, Female Sockets Selection Notes

Select this model for high-pin-count single-row requirements where space efficiency is critical. The 1.27mm pitch allows dense routing compared to standard 2.54mm connectors. Consider the push-pull feature if mechanical retention during vibration is necessary. Verify thermal limits align with the application's operational environment.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Archer M52 family, characterized by compact form factors and robust locking mechanisms. It serves as a female receptacle counterpart to male headers within the same series. The design prioritizes reliability in demanding environments while maintaining a low profile suitable for modern electronic assemblies.

Headers, Receptacles, Female Sockets Replacement Considerations

M52-5004045 is functionally compatible with other M52-series 40-position single-row receptacles sharing identical pitch and locking styles. Cross-reference mating part numbers to ensure mechanical fit. No direct substitute exists outside the M52 family without redesigning the PCB footprint.
