SL 11 139 2 S

Headers, Male Pins Overview

The SL 11 139 2 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 two positions. The component utilizes a through-hole mounting style with straight termination. Contact surfaces are selectively gold-plated over a nickel base, while the contact sleeves feature a nickel plating of at least 0.2 micrometers. The housing is constructed from polyamide (PA46), rated UL 94 V-0 for flammability. The operating temperature range spans from -40°C to +163°C, with soldering capability at 260°C for 10 seconds.

Headers, Male Pins Feature Summary

• Precision-engineered one-row male header configuration with a 0.635 mm contact pitch
• Selective gold plating on contact surfaces ensures reliable signal transmission
• Polyamide (PA46) insulation material provides high thermal stability and UL 94 V-0 rating
• Through-hole straight termination design facilitates standard PCB assembly processes

Headers, Male Pins Applications

• General-purpose electronic board interconnections
• Signal routing in compact circuit assemblies
• Prototype development requiring precise 0.635 mm spacing

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' indicates selective gold plating as documented in official Fischer Elektronik datasheets. Confirm that the two-position count aligns with system requirements. Ensure compatibility with 0.635 mm mating pins. Check for RoHS compliance status if required by project specifications. Validate thermal ratings against operational environment constraints.

Headers, Male Pins Selection Notes

Select this component when a 0.635 mm pitch is mandatory rather than the standard 2.54 mm. The selective gold plating suits applications requiring corrosion resistance without full gold coverage costs. Consider the PA46 insulation for higher temperature environments compared to standard nylon. Verify that the single-row format fits within available board width constraints.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL 11 series, which specializes in precision male headers with fine 0.635 mm pitches. Unlike the broader SL family that includes 2.54 mm variants, this series targets dense interconnect needs. The SL 11 139 designation typically refers to the dimensional profile or series identifier within the manufacturer's catalog structure.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch and two-position count. Verify identical selective gold plating specifications to maintain electrical performance. Ensure mechanical dimensions, particularly height and pin length, fit existing board layouts. Cross-reference with Fischer Elektronik SL 11 series documentation for equivalent configurations.
