SL 11 139 4 G

Headers, Male Pins Overview

The SL 11 139 4 G is a male header connector from Fischer Elektronik, designed for through-hole PCB mounting. It features a single row with four contacts and a 2.54 mm (0.100 inch) pitch. The contacts are made of copper-tin alloy with a tin surface finish, providing a mating contact length of 8.10 mm and a post length of 3.00 mm. The total contact length is 13.90 mm, with an insulation height of 2.80 mm. The connector utilizes square-shaped terminals and PA46 nylon insulation material.

Headers, Male Pins Feature Summary

• Single-row male header configuration for reliable signal transmission
• Through-hole mounting technology for secure PCB attachment
• Tin-plated copper-tin contacts ensuring corrosion resistance

Headers, Male Pins Applications

• General-purpose electronic circuit interconnections
• PCB-to-PCB communication links
• Connector assembly in consumer electronics

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required housing or accessory components. Confirm that the tin surface finish meets the intended environmental requirements for solderability and long-term reliability. Check datasheet specifications for operating temperature ranges and current ratings before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row male header is required for standard 2.54 mm pitch applications. Consider the 4-position count and through-hole mounting style for designs needing robust mechanical fixation. Ensure the square contact shape aligns with the mating socket geometry and that the insulation material suits the thermal environment.

Headers, Male Pins Part Context

This part belongs to the SL 11 series of male headers manufactured by Fischer Elektronik. The series offers various contact counts ranging from one to thirty-six positions while maintaining a consistent 2.54 mm grid spacing. These connectors are engineered for precision engineering applications requiring stable electrical connections in compact spaces.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include SL 11 139 1 G through SL 11 139 36 G, which share identical mechanical and electrical characteristics but differ in contact count. Verify pin count requirements before swapping to ensure functional compatibility.
