SL 11 139 32 Z

Headers, Male Pins Overview

The SL 11 139 32 Z is a single-row male header connector manufactured by Fischer Elektronik. It features a 0.635 mm pitch and contains 32 positions. The connector utilizes through-hole termination with square contact pins made of copper-tin alloy. Contact surfaces are finished with tin plating, measuring 4.00 µm in thickness. The insulating body is constructed from polyamide (PA46). Key dimensions include a mating contact length of 5.40 mm, a post length of 3.00 mm, and an overall contact length of 11.20 mm. The insulation height is 2.80 mm.

Headers, Male Pins Feature Summary

• Single-row male pin configuration for standard board-to-board or cable connections
• Precision 0.635 mm pitch ensures accurate alignment with mating receptacles
• Through-hole mounting design provides secure mechanical fixation on printed circuit boards
• Tin-plated copper-tin contacts offer reliable conductivity and corrosion resistance

Headers, Male Pins Applications

• Signal transmission in industrial control systems
• Interconnection modules in measurement and testing equipment
• General-purpose electronic assemblies requiring precise pin spacing

Headers, Male Pins Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's current datasheet to confirm plating specifications and material composition. Ensure the required pin count matches the 32-position variant exactly. Cross-reference the 0.635 mm pitch requirement with mating components to guarantee compatibility. Confirm RoHS compliance status if restricted substances are mandated for the target application environment.

Headers, Male Pins Selection Notes

Select this component when a 0.635 mm pitch is strictly required rather than the standard 2.54 mm. Evaluate the mechanical stability provided by the through-hole mounting method against surface-mount alternatives. Consider the PA46 insulation material properties regarding thermal resistance and chemical exposure. Assess the tin plating thickness suitability for the expected number of mating cycles in the intended operational lifecycle.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL 11 series, which specializes in precision signal connectors. The series offers various pin counts and configurations tailored for high-density applications. The SL 11 line emphasizes robust construction and precise dimensional tolerances, making it suitable for environments demanding reliable electrical performance over extended periods.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch and 32-pin count. Verify that alternative headers share the same through-hole termination style and PA46 insulation material. Ensure mating connectors are compatible with the specific contact geometry and tin plating finish to prevent interface issues.
