SL 11 124 21 Z

Headers, Male Pins Overview

The SL 11 124 21 Z is a single-row male pin header connector manufactured by Fischer Elektronik. It features a 0.635 mm pitch and contains 21 positions. The connector utilizes square contact pins with a tin-plated copper-tin alloy construction. Designed for through-hole mounting, it offers a total contact length of 0.441 inches (11.20 mm), with a mating contact length of 0.213 inches (5.40 mm) and a column contact length of 0.118 inches (3.00 mm). The insulating housing is made of polyamide (PA46) nylon, providing an insulation height of 0.110 inches (2.80 mm).

Headers, Male Pins Feature Summary

• Single-row configuration with 0.635 mm pitch spacing.
• Through-hole solder connection for secure PCB mounting.
• Square-shaped tin-plated contacts for reliable signal transmission.

Headers, Male Pins Applications

• General-purpose PCB interconnections.
• Signal routing in electronic assemblies.

Headers, Male Pins Procurement Notes

Verify the exact part number suffix against manufacturer documentation to ensure correct plating and material specifications. Confirm that the 0.635 mm pitch variant matches the design requirements, as Fischer Elektronik offers multiple pitch options within the SL 11 series. Cross-reference the 21-position count with schematic footprints to prevent assembly errors.

Headers, Male Pins Selection Notes

Select this component when a compact single-row header with fine 0.635 mm spacing is required. Ensure the PCB layout accommodates the specific through-hole pad dimensions associated with the 0.635 mm grid. Consider the PA46 insulation material properties for thermal stability during soldering processes compared to standard nylon variants.

Headers, Male Pins Part Context

This model belongs to the SL 11 124 series of male headers from Fischer Elektronik. The series provides various pole counts and pitch configurations for board-to-board or cable connections. The SL 11 124 designation indicates a specific sub-family within their broader PCB connector portfolio, focusing on high-density interconnect solutions.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 21-position count, and through-hole termination method. Verify compatibility with existing mating connectors regarding contact geometry and insulation height. Alternative Fischer Elektronik parts may require re-verification of footprint dimensions due to pitch variations.
