SL 11 124 21 S

Headers, Male Pins Overview

The SL 11 124 21 S is a male header connector from the Fischer Elektronik SL 11 series. It features a single row with 21 contacts and a pitch of 0.635 mm (0.025 inches). The connector utilizes through-hole termination for PCB mounting. Contact surfaces are tin-plated to ensure reliable electrical connections. The housing is constructed from polyamide, providing mechanical stability and insulation.

Headers, Male Pins Feature Summary

• Single-row male header configuration designed for compact board-to-board or cable-to-board interconnections
• Precision 0.635 mm contact pitch ensures accurate alignment and secure mating with compatible sockets
• Tin-plated contact surfaces provide corrosion resistance and stable conductivity for signal transmission
• Through-hole soldering technique offers robust mechanical fixation on printed circuit boards

Headers, Male Pins Applications

• Industrial control systems requiring dense signal routing
• Test and measurement equipment interfaces
• Consumer electronics internal connectivity
• Automotive electronic modules

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'S' corresponds to the tin-plated variant when sourcing. Confirm that the 21-contact count matches the design requirements. Ensure compatibility with mating connectors using the same 0.635 mm pitch standard. Check RoHS compliance status if required by project specifications.

Headers, Male Pins Selection Notes

Select this component when space constraints necessitate a high-density single-row layout. The 0.635 mm pitch allows for more contacts per unit length compared to standard 2.54 mm headers. Consider the tin plating for general-purpose applications where gold plating is not strictly necessary for wear resistance.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL 11 family of precision male headers. The series is characterized by its small form factor and high pin counts within limited board areas. The SL 11 124 designation indicates the specific housing style and contact arrangement within the product line.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, single-row configuration, and 21-pin count. Verify that alternative manufacturers offer comparable tin-plated contacts and similar thermal resistance profiles during soldering processes.
