SL 11 139 4 S

Headers, Male Pins Overview

The SL 11 139 4 S is a male header connector manufactured by Fischer Elektronik. It features a single row of contacts with a pitch of 0.635 mm (25.4 mil). The component has 4 positions and utilizes through-hole mounting for PCB integration. Contact materials are copper alloy with tin plating to ensure reliable electrical connections. The housing is constructed from polyamide (PA46), providing necessary insulation and mechanical stability. This connector type is designed for high-density electronic manufacturing applications requiring robust signal transmission.

Headers, Male Pins Feature Summary

• Single-row male header configuration for compact circuit board layouts
• Through-hole termination method ensuring secure mechanical attachment
• Tin-plated copper alloy contacts for corrosion resistance and conductivity
• Polyamide (PA46) insulating housing for thermal and electrical stability

Headers, Male Pins Applications

• High-density electronic manufacturing assemblies
• Signal transmission interfaces in compact devices
• Robust mechanical connection points for PCB-to-PCB or PCB-to-cable links

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'S' against the manufacturer's current datasheet to confirm exact contact length, housing color coding, or packaging variations. Ensure the required pin count matches the four-position specification. Cross-reference the RoHS compliance status if environmental regulations apply to your assembly process. Confirm that the 0.635 mm pitch aligns with your mating connector requirements.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row male header is required for dense PCB arrangements. The 0.635 mm pitch allows for tight spacing between adjacent connectors. Consider the through-hole technology compatibility with your manufacturing capabilities. Evaluate the PA46 material properties if higher temperature resistance is needed compared to standard nylon variants. Ensure the 4-pin count meets the specific signal or power line requirements of the design.

Headers, Male Pins Part Context

The SL 11 series represents Fischer Elektronik's range of precision male headers designed for various density and performance needs. The SL 11 139 variant specifically denotes a particular contact length and housing dimension set within this family. These components are engineered for reliability in industrial and commercial electronics, offering consistent performance across different environmental conditions while maintaining precise dimensional tolerances for automated assembly processes.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 4-position count, and single-row male header format. Verify that alternative manufacturers offer compatible through-hole termination and similar PA46 housing materials. Check if generic equivalents provide equivalent tin plating thickness and contact force specifications to ensure reliable mating without damaging the female counterpart.
