SL 11 139 26 S

Headers, Male Pins Overview

The SL 11 139 26 S is a single-row male pin header connector manufactured by Fischer Elektronik. It features a 0.635 mm (0.025 inch) pitch and contains 26 positions. The contacts are gold-plated with a nickel underlayer, while the insulation material is glass-filled polyamide (PA46). Designed for through-hole mounting, it operates within a temperature range of -40°C to +163°C and meets UL 94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Precision-engineered one-row configuration with 0.635 mm spacing
• Gold-plated contacts with nickel underlayer for reliable conductivity
• Glass-filled polyamide insulation ensuring high thermal stability

Headers, Male Pins Applications

• High-density PCB interconnections requiring precise alignment
• Industrial control systems operating in elevated temperatures
• Test and measurement equipment connectors

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' indicates selective gold plating on the contact area as per official datasheets. Confirm that the 26-position count matches the required circuit density. Ensure compatibility with 0.635 mm pitch mating sockets. Check for RoHS compliance status if required by project specifications.

Headers, Male Pins Selection Notes

Select this component when a fine-pitch 0.635 mm male header is necessary for space-constrained designs. The gold plating offers superior corrosion resistance compared to tin variants. Consider the PA46 insulation for applications involving reflow soldering or high ambient heat. Validate mechanical fit against existing board layouts.

Headers, Male Pins Part Context

This part belongs to the SL 11 139 series of precision headers from Fischer Elektronik. These connectors are designed for robust electronic assemblies where signal integrity and mechanical stability are critical. The series typically supports various contact counts and plating options to suit different environmental requirements.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 0.635 mm pitch and 26-pin count. Verify that alternative parts support the same through-hole termination method and UL 94 V-0 rating. Ensure mating socket compatibility with the specific contact geometry of the SL 11 139 series.
