M80-7004542

Overview

The M80-7004542 is a Datamate M80 series male header connector manufactured by Harwin Inc. It features a vertical through-hole mounting style with 45 positions arranged in a 3-row configuration. The connector utilizes a 2.00mm (0.079 inch) pitch for both contact and row spacing. Contacts are made of phosphor bronze with gold plating, offering a current rating of 2.2A and a voltage rating of 120V. The housing is constructed from black polyamide material rated UL94 V-0, ensuring flame resistance. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Vertical through-board mounting design for direct PCB integration
• Three-row shrouded header configuration providing high density
• Gold-plated phosphor bronze contacts for reliable signal transmission
• Polyamide housing with UL94 V-0 flammability rating

Applications

• Industrial control system interconnections
• Power distribution boards requiring high pin counts
• Automotive electronics assemblies
• Telecommunications equipment backplanes

Procurement Notes

Verify the specific contact plating thickness and housing material grade against the official Harwin datasheet before finalizing procurement. Ensure that the selected mating socket corresponds to the Datamate M80 female series to guarantee mechanical compatibility and electrical performance. Confirm that the vertical orientation aligns with the assembly space constraints and thermal management requirements of the target application environment.

Selection Notes

Select this component when a high-density, vertically oriented male header is required for through-hole soldering processes. The 3-row layout maximizes connection capacity within a limited footprint. Consider the 2.2A current rating per contact to ensure adequate power handling for the intended circuit loads. Verify that the 120V voltage rating meets the system's electrical isolation requirements and that the operating temperature range covers the environmental conditions.

Part Context

This part belongs to the Datamate M80 family, designed for robust board-to-board and cable connections. The M80 series is characterized by its high durability and secure locking mechanisms. The M80-7004542 specifically addresses applications needing a large number of vertical interconnects. It complements other M80 series components such as sockets and cable assemblies to form complete connectivity solutions.

Replacement Considerations

Direct substitutes must match the 45-position, 3-row, 2.00mm pitch specification. Verify that alternative parts maintain the same vertical through-hole mounting style and phosphor bronze contact material. Ensure the replacement housing material offers equivalent UL94 V-0 ratings and thermal stability up to 125°C to preserve system reliability.
