M50-4910545

Headers, Male Pins Overview

The M50-4910545 is a shrouded pin header from the Harwin ARCHER M50 series, designed for surface mount technology. It features a dual in-line configuration with 10 positions (5+5) arranged in two rows. The connector utilizes a precise 1.27 mm pitch and includes mounting pegs for secure PCB alignment during assembly. Constructed with phosphor bronze contacts plated with gold, it ensures reliable signal transmission. The housing is made of black liquid crystal polymer (LCP), offering high thermal stability and UL 94 V-0 flammability ratings. Rated for 1 A current and 300 V voltage, it operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Dual row shrouded design provides mechanical protection and prevents misalignment during mating.
• Integrated mounting pegs ensure accurate positioning on the printed circuit board.
• Gold-plated phosphor bronze contacts offer low contact resistance and corrosion resistance.
• Liquid crystal polymer housing supports high-temperature soldering processes.

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Wire-to-board connections requiring precise alignment
• Automotive electronic control units
• Industrial communication modules

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact pin count and housing variations. Ensure compatibility with automated pick-and-place equipment due to the presence of mounting pegs. Check RoHS compliance documentation for regional regulatory requirements. Confirm that the selected reel or tube packaging matches your production line capacity.

Headers, Male Pins Selection Notes

Select this component when a compact, high-reliability connection is required for dense layouts. The 1.27 mm pitch allows for significant I/O density in limited space. Consider the shrouded design if environmental contamination or accidental shorting is a concern. Verify that the operating temperature range meets the specific application's thermal profile.

Headers, Male Pins Part Context

This part belongs to the ARCHER M50 series, known for its robust construction and fine-pitch capabilities. The series is widely used in demanding environments where reliability is critical. The M50-4910545 specifically addresses the need for small-footprint connectors with enhanced mechanical stability through its pegged design.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other 1.27 mm pitch SMT headers from different manufacturers, but mechanical dimensions and peg placement must be verified. Cross-reference with Harwin's discontinuation notices if available. Ensure any alternative maintains the same current rating and insulation material properties.
