M22-2542046

Headers, Male Pins Overview

The Harwin M22-2542046 is a board-to-board connector header from the M22 series, featuring a 2.00mm pitch and 40 positions in a dual-row configuration. Designed for through-hole mounting with right-angle orientation, it utilizes phosphor bronze contacts with tin plating to ensure reliable signal transmission. The housing is constructed from UL94 V-0 rated polyamide (PA6T), providing high thermal stability and flame resistance suitable for reflow soldering processes. Rated for 1A per contact, this component supports operating temperatures ranging from -40°C to +105°C, making it appropriate for dense PCB layouts requiring robust mechanical and electrical performance.

Headers, Male Pins Feature Summary

• Right-angle through-hole pin strip design optimized for space-constrained board-to-board applications
• High-temperature resistant PA6T insulation material compatible with standard surface mount reflow profiles
• Durable tin-plated phosphor bronze contacts engineered for consistent electrical connectivity

Headers, Male Pins Applications

• Embedded PC motherboard interconnections
• Communication equipment internal circuit boards
• Industrial control system drive modules

Headers, Male Pins Procurement Notes

Verify the specific suffix code against official Harwin documentation to confirm contact plating type and orientation, as variations exist within the M22 family. Ensure the selected variant matches the required current rating and thermal specifications for the target application environment. Cross-reference the manufacturer part number with distributor catalogs to confirm availability status and lead times prior to finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this component when a right-angle, dual-row header with a 2.00mm pitch is required for through-hole assembly. Consider the 1A current rating and -40°C to +105°C temperature range to ensure compatibility with operational demands. Verify that the tin-plated contacts meet the corrosion resistance requirements of the intended environment compared to gold-plated alternatives.

Headers, Male Pins Part Context

The M22 series represents Harwin's industrial standard connector line, characterized by compact dimensions and high reliability. This specific model belongs to the horizontal pin header subset, designed to facilitate vertical mating connections on adjacent PCBs. The series is widely adopted in consumer electronics and large-scale electronic systems due to its balance of density and durability.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M22 series headers with identical 2.00mm pitch and 40-position dual-row configurations. Verify mechanical footprint and pin alignment before substitution. Alternative manufacturers offering 2.00mm pitch right-angle through-hole headers may be considered if dimensional tolerances match.
