SL 11 139 28 S

Headers, Male Pins Overview

The SL 11 139 28 S is a single-row male header connector manufactured by Fischer Elektronik. It features a 0.635 mm (0.025 inch) contact pitch and accommodates 28 positions. Designed for through-hole mounting, the component utilizes a PA46 polyamide insulator and tin-plated copper contacts with a 157.5 µin (4.00 µm) thickness. The assembly includes a straight pin configuration with an overall contact length of 0.547 inches (13.90 mm), ensuring reliable electrical interconnection in standard board-to-board applications.

Headers, Male Pins Feature Summary

• Single-row male header design for direct PCB insertion
• Precision 0.635 mm contact pitch for high-density routing
• Tin-plated copper contacts for corrosion resistance
• PA46 polyamide insulation for thermal stability

Headers, Male Pins Applications

• General-purpose board-to-board interconnections
• Industrial control system signal routing
• Electronic instrumentation circuit boards

Headers, Male Pins Procurement Notes

Verify that the specific suffix 'S' aligns with the required termination style and packaging format for your production line. Confirm the 28-position count matches the target footprint to avoid soldering defects. Ensure the tin plating specification meets the environmental requirements of the final assembly. Cross-reference the official datasheet for exact mechanical tolerances before placing orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row male header is required for dense signal routing. The 0.635 mm pitch allows for compact board layouts compared to standard 0.100 inch spacing. Verify that the through-hole termination method suits the manufacturing process. Consider the PA46 material properties if high-temperature reflow or operation is anticipated in the application environment.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL 11 series, which specializes in precision connectors with fine pitches. The series offers various row counts and position options to support diverse electronic assembly needs. As a male header, it is designed to mate with corresponding female sockets or cable assemblies, providing a robust connection solution for modern electronics.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same manufacturer family include models with identical pitch but different position counts, such as SL 11 139 24 S or SL 11 139 36 S. Verify mechanical compatibility and mating interface dimensions before swapping parts. Generic replacements may lack the specific 0.635 mm pitch precision required for this application.
