M20-9741146

Headers, Male Pins Overview

The M20-9741146 is a male pin header connector from the Harwin M20 series, designed for board-to-board or cable applications. It features a 22-position configuration with a 2.54 mm (0.100 inch) pitch across two rows. The component utilizes straight through-hole termination and includes an integrated latching system for secure mating. Constructed with brass contacts finished in tin plating, it ensures reliable conductivity. The housing is made of black nylon, rated for operation between -40°C and +105°C.

Headers, Male Pins Feature Summary

• Incorporates a push-pull latching mechanism to ensure secure connection retention during vibration and thermal cycling.
• Features a dual-row male pin design compatible with standard 2.54 mm spacing requirements for dense circuit layouts.
• Utilizes tin-plated brass contacts to provide corrosion resistance and stable electrical performance over the operating temperature range.

Headers, Male Pins Applications

• Industrial control systems requiring robust mechanical retention
• Consumer electronics with space-constrained board-to-board interfaces
• Automotive electronic modules needing vibration-resistant connections

Headers, Male Pins Procurement Notes

Verify the specific orientation and latching style against the target assembly drawing before ordering. Confirm that the receiving PCB pads match the 2.54 mm dual-row footprint. Check for RoHS compliance status if required by project specifications. Ensure the tin plating specification meets the solderability requirements of the manufacturing process.

Headers, Male Pins Selection Notes

Select this model when a secure latching interface is critical for the application environment. The dual-row format allows for higher pin density compared to single-row alternatives. Consider the straight mounting angle for standard vertical board stacking. Evaluate the thermal rating to ensure compatibility with the expected operating conditions of the host device.

Headers, Male Pins Part Context

This component belongs to the M20 series, which is characterized by its high-reliability latching headers. The series is widely used in demanding environments where standard connectors might fail due to mechanical stress. The M20-9741146 specifically addresses the need for a 22-pin solution with enhanced retention capabilities.

Headers, Male Pins Replacement Considerations

M20-9741146 is a right-angle variant; verify if the original design requires a straight header. Cross-reference with other M20 series parts for similar pin counts but different latching mechanisms. Ensure that any substitute maintains the same 2.54 mm pitch and dual-row configuration to fit existing tooling.
