M22-2012546

Headers, Male Pins Overview

The M22-2012546 is a 25-position, single-row vertical pin header assembly from the Harwin M22 series. It features a 2.00mm pitch and utilizes through-hole termination for board-to-board connections. The connector employs phosphor bronze contacts with gold plating to ensure reliable signal transmission. Constructed with a nylon housing, it supports a rated current of 1A per contact and operates within a temperature range of -40°C to +105°C. The design includes a tail pin length of 3.4mm and a mating pin length of 3.5mm, providing secure mechanical engagement without an integrated cover.

Headers, Male Pins Feature Summary

• Vertical orientation facilitates direct board stacking in compact assemblies
• Gold-plated phosphor bronze contacts provide corrosion resistance and stable conductivity
• Nylon insulation material ensures thermal stability and UL94 V-0 flammability rating

Headers, Male Pins Applications

• High-density board-to-board interconnects
• Industrial control module interfaces
• Telecommunications equipment backplanes

Headers, Male Pins Procurement Notes

Verify the specific part number suffix against official Harwin documentation to confirm contact plating and housing material specifications. Ensure that the selected variant matches the required voltage rating and current capacity for the target application environment. Cross-reference the manufacturing date code to confirm component availability and compliance with current environmental regulations such as RoHS standards before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a vertical, single-row configuration is required for space-constrained designs. The 2.00mm pitch allows for high pin density while maintaining adequate spacing. Consider the through-hole mounting method for robust mechanical fixation compared to surface mount alternatives. Evaluate the 1A current rating against the total load requirements of the connected circuitry to prevent overheating during continuous operation.

Headers, Male Pins Part Context

This component belongs to the M22 series, which is characterized by its push-pull locking mechanism and modular design options. The series offers various row counts and orientations to suit different connectivity needs. As a pin header, it serves as the male counterpart to compatible socket connectors, enabling reversible connections between printed circuit boards in electronic systems.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 25-position, 2.00mm pitch vertical pin headers from the same manufacturer or third-party vendors with matching mechanical dimensions and electrical ratings. Verify that alternative parts support the same through-hole termination and gold plating specifications to maintain interface compatibility.
