SL 11 139 18 S

Headers, Male Pins Overview

The Fischer Elektronik SL 11 139 18 S is a single-row male header connector designed for through-hole PCB mounting. It features 18 positions with a 0.100 inch (2.54 mm) contact spacing. The contacts are square-shaped pins made of copper-tin alloy, plated with tin measuring 157.5 µin (4.00 µm). The assembly utilizes polyamide (PA46) insulation and has an overall contact length of 0.547 inches (13.90 mm), with a mating contact length of 0.319 inches (8.10 mm) and a column contact length of 0.118 inches (3.00 mm).

Headers, Male Pins Feature Summary

• Single-row male pin configuration for standard through-hole board integration.
• Square contact cross-section ensuring precise mechanical alignment during mating.
• Polyamide (PA46) insulation material providing structural stability.

Headers, Male Pins Applications

• General electronic circuit interconnections requiring reliable signal transmission.
• Industrial control systems utilizing standard 2.54 mm pitch connectors.
• Test and measurement equipment interfaces.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'S' against the manufacturer's current datasheet to confirm plating specifications and availability. Ensure the required pin count matches the 18-position variant exactly. Confirm that the through-hole mounting style aligns with the target printed circuit board design constraints before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row male header with 18 positions and 2.54 mm spacing is required. The square pin design offers distinct mechanical advantages over round pins in certain mating scenarios. Verify that the operating temperature range and thermal resistance meet the application requirements for soldering processes.

Headers, Male Pins Part Context

This part belongs to the SL 11 139 series of male headers from Fischer Elektronik. The series is characterized by a consistent 2.54 mm grid and single-row layout. Variations within the series typically differ by the number of positions and specific contact plating options, while maintaining identical physical dimensions and mounting characteristics.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 18-position count, 2.54 mm pitch, and through-hole mounting type. Verify compatibility of the square pin profile with existing mating receptacles. Cross-reference specific plating thicknesses if corrosion resistance or conductivity requirements are critical to the system performance.
