M20-9750446

Headers, Male Pins Overview

The Harwin M20-9750446 is a single-row pin header from the M20 series, designed for board-to-board and wire-to-board connections. It features a 2.54 mm pitch with four contacts housed in black nylon. The connector utilizes brass contacts with tin plating and supports through-hole installation via horizontal PC tails. It operates within a temperature range of -40°C to +105°C and carries a current rating of 3A.

Headers, Male Pins Feature Summary

• Horizontal through-hole mounting configuration for PCB integration
• Tin-plated brass contacts ensure reliable electrical conductivity
• Black nylon housing provides structural stability and insulation

Headers, Male Pins Applications

• Board-to-board interconnects
• Wire-to-board connections
• General electronic assembly requiring low-profile headers

Headers, Male Pins Procurement Notes

Verify the specific orientation suffix against project requirements, as this model specifies horizontal tails. Confirm that the 2.54 mm pitch and 4-position count align with the target PCB footprint. Ensure compatibility with mating connectors regarding contact height and plating specifications before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a horizontal tail configuration is required for space-constrained or specific mechanical alignment applications. The 4-contact size suits low-density signal routing. Verify that the 3A current rating and 105°C thermal limit meet the operational environment constraints of the target system design.
