SL 11 139 27 Z

Headers, Male Pins Overview

The Fischer Elektronik SL 11 139 27 Z is a single-row male pin header connector designed for through-hole PCB mounting. It features 27 contacts with a 0.100-inch (2.54 mm) pitch. The connector utilizes square-shaped pins made from copper-tin alloy, plated with tin on both the mating and post sections. The mating contact length measures 0.319 inches (8.10 mm), while the post contact length is 0.118 inches (3.00 mm). The total contact length is 0.547 inches (13.90 mm), and the insulation height is 0.110 inches (2.80 mm). The housing is constructed from polyamide (PA46).

Headers, Male Pins Feature Summary

• Single-row configuration with square-shaped pins for secure board-to-board or wire-to-board connections.
• Through-hole mounting style ensuring stable mechanical attachment to printed circuit boards.
• Tin-plated copper-tin alloy contacts providing reliable electrical conductivity and corrosion resistance.

Headers, Male Pins Applications

• General-purpose electronic assemblies requiring signal interconnection.
• Industrial control systems utilizing standard 2.54 mm pitch connectors.

Headers, Male Pins Procurement Notes

Verify the specific part number suffix against the manufacturer's current datasheet to confirm contact plating specifications and material composition. Ensure that the required contact count matches the 27-position configuration. Confirm that the through-hole mounting style aligns with the target PCB design constraints and thermal requirements during assembly processes.

Headers, Male Pins Selection Notes

Select this component when a single-row, 2.54 mm pitch male header is required for through-hole applications. Consider the 27-contact capacity and square pin geometry for compatibility with mating sockets. Evaluate the polyamide insulation material and tin plating suitability for the operating environment and soldering conditions compared to alternative series options.

Headers, Male Pins Part Context

This component belongs to the Fischer Elektronik SL 11 series of male pin headers. The series offers various contact counts and configurations optimized for precision engineering in electronic interconnects. The SL 11 139 variant specifically denotes the single-row straight design with standard 2.54 mm spacing, widely used in signal connectivity applications across multiple industries.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Fischer Elektronik SL 11 series headers with matching 27 positions and 2.54 mm pitch, such as SL 11 139 27 S if gold plating is preferred. Verify that any replacement maintains the same through-hole mounting style, square pin shape, and polyamide insulation material to ensure mechanical and electrical compatibility.
