M22-2541105

Headers, Male Pins Overview

The M22-2541105 is a male pin header connector from the Harwin M22 series, designed for board-to-board or cable applications. It features a double-row configuration with 11+11 positions and a 2.00mm (0.079 inch) pitch. The connector utilizes gold-plated phosphor bronze contacts for reliable signal transmission and is housed in black polyamide insulation rated UL94 V-0 for high-temperature stability. It employs a horizontal through-hole termination style with jackscrew fixing mechanisms to ensure secure mechanical attachment. The unit supports a current rating of 1A per contact and operates within a temperature range of -40°C to 105°C.

Headers, Male Pins Feature Summary

• Double-row design with jackscrew fixing for secure mechanical retention
• Gold-plated phosphor bronze contacts ensuring low resistance and corrosion resistance
• High-temperature UL94 V-0 rated polyamide housing for thermal stability
• Horizontal through-hole termination for robust PCB mounting

Headers, Male Pins Applications

• Industrial control systems requiring secure connections
• Automotive electronics modules
• Communication equipment backplanes
• Test and measurement instrumentation

Headers, Male Pins Procurement Notes

Verify the specific suffix code to confirm contact plating thickness and material composition, as variations exist within the M22 series. Ensure the ordering part number matches the required row count and pin configuration. Confirm that the jackscrew mechanism aligns with the assembly space constraints. Cross-reference the datasheet for mating connector specifications to guarantee compatibility. Check for RoHS compliance status if environmental regulations apply to the final product.

Headers, Male Pins Selection Notes

Select this component when a double-row header with positive locking is required. The horizontal orientation suits boards with limited vertical clearance above the PCB. The 2.00mm pitch offers a balance between density and spacing. Gold plating is essential for environments where oxidation could compromise signal integrity. The jackscrew feature prevents accidental disconnection during vibration or thermal cycling.

Headers, Male Pins Part Context

The M22 series by Harwin Inc. is engineered for demanding industrial and automotive environments. These connectors are known for their durability and secure latching options. The M22-2541105 specifically addresses the need for high-reliability interconnects in compact spaces. Its design emphasizes long-term connection stability under harsh conditions.

Headers, Male Pins Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate other Harwin M22 variants with similar pitch and row configurations only if mechanical dimensions and electrical ratings match exactly. Verify that any alternative maintains the same jackscrew fixing mechanism and contact material properties.
