M50-4905045

Headers, Male Pins Overview

The Harwin M50-4905045 is a surface-mount pin header assembly from the ARCHER series. It features a 1.27 mm pitch and a dual in-line (DIL) configuration with 50 positions arranged in two rows. The connector utilizes gold-plated phosphor bronze contacts housed in a black liquid crystal polymer (LCP) body, rated for UL 94 V-0 flammability. Designed for straight installation, it supports a current rating of 1 A and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Shrouded design provides mechanical alignment and protection for mating connections.
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance.
• Integrated mounting pegs facilitate precise placement during automated surface-mount assembly.

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Embedded system module interfaces
• Industrial control unit signal routing

Headers, Male Pins Procurement Notes

Verify the specific contact count and row configuration against the datasheet before ordering. Confirm that the surface-mount footprint matches the target PCB layout. Ensure compatibility with the mating socket height requirements for the intended application environment.

Headers, Male Pins Selection Notes

Select this component when a high-pin-count, low-profile connection is required. The 1.27 mm pitch allows for dense circuit layouts. Consider the operating temperature range and current rating to ensure suitability for the specific electrical load and environmental conditions of the final product.
