M22-2740846

Headers, Male Pins Overview

The Harwin M22-2740846 is a dual in-line horizontal pin header from the M22 series, designed for board-to-board connections. It features an 8+8 position configuration with a 2.00 mm pitch and row spacing. The connector utilizes solder pin termination for right-angle surface mounting or through-hole integration, depending on specific variant specifications, though this part is typically associated with horizontal headers. Contact plating is tin over phosphor bronze, ensuring reliable conductivity. It operates within a temperature range of -40°C to +105°C and meets UL 94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Dual in-line horizontal design facilitates compact board stacking.
• Tin-plated phosphor bronze contacts provide corrosion resistance.
• Nylon housing ensures mechanical stability and electrical insulation.

Headers, Male Pins Applications

• High-density electronic module interconnects
• Industrial control system board interfaces
• Telecommunications equipment signal routing

Headers, Male Pins Procurement Notes

Verify the exact termination style (SMD vs. Through-Hole) against the manufacturer datasheet, as M22 series variants can differ significantly in mounting requirements. Confirm RoHS compliance status and lead times with authorized distributors, as availability may fluctuate based on production cycles. Ensure compatibility with mating socket housings before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is required between adjacent PCBs. The 2.00 mm pitch allows for significant I/O density in constrained spaces. Consider the horizontal orientation for space-saving designs where vertical headers would exceed height restrictions. Validate thermal performance requirements against the +105°C maximum operating limit.

Headers, Male Pins Part Context

This part belongs to the Harwin M22 series, a widely used family of connectors known for their robustness and versatility in harsh environments. The M22 line offers various configurations including single and double rows, different pitches, and multiple termination methods, making it suitable for diverse industrial and commercial applications requiring reliable signal transmission.

Headers, Male Pins Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Engineers should evaluate other Harwin M22 series variants with matching pitch and position counts if this specific orientation or plating is unavailable. Cross-compatibility with generic 2.00mm pitch headers requires careful verification of mechanical dimensions and contact geometry.
