M22-2040405

Headers, Male Pins Overview

The Harwin M22-2040405 is a male pin header from the M22 series, designed for wire-to-board connections. It features an 8-position configuration arranged in a double inline layout (2 rows of 4). The connector utilizes a 2 mm pitch and is constructed with phosphor bronze contacts plated with gold. It employs a right-angle through-hole solder termination with a 3.5 mm tail length. The housing is made of black nylon, rated UL 94 V-0. Electrical specifications include a current rating of 1 A per contact and a voltage rating of 650 VAC. The operating temperature range spans from -40°C to +105°C.

Headers, Male Pins Procurement Notes

Verify that the specific part number M22-2040405 matches the required 8-position, 2-row, right-angle configuration. Confirm that the gold plating specification aligns with application requirements for corrosion resistance and conductivity. Ensure the through-hole solder tail length of 3.5 mm is compatible with the target PCB thickness and manufacturing process capabilities before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a right-angle, double-row male header is required for 2 mm pitch applications. The 1 A current rating per contact suits low-power signal and control circuits. Consider the gold plating for environments where oxidation resistance is critical. Verify that the 650 VAC insulation rating meets the system's electrical safety standards and that the -40°C to +105°C temperature range covers the operational environment.
