SL 11 190 27 G

Headers, Male Pins Overview

The SL 11 190 27 G is a single-row male pin header connector manufactured by Fischer Elektronik. It features 27 positions with a 0.100 inch (2.54 mm) pitch, designed for through-hole mounting on printed circuit boards. The contacts are constructed from copper-tin alloy and finished with nickel plating followed by a gold coating of at least 0.2 micrometers to ensure reliable conductivity. The insulating body is made of polyamide PA 4.6 glass-filled material, providing thermal stability and mechanical strength. Rated for 3 A nominal current and 250 V AC, it supports a test voltage of 2000 V.

Headers, Male Pins Feature Summary

• Gold-plated contact finish ensures high corrosion resistance and stable electrical performance
• Glass-filled polyamide insulation provides robust mechanical integrity and heat resistance
• Through-hole design secures the connector firmly to the PCB substrate

Headers, Male Pins Applications

• General-purpose board-to-board interconnections
• Wire-to-board signal routing in electronic assemblies
• Industrial control unit interface modules

Headers, Male Pins Procurement Notes

Verify that the specific suffix 'G' corresponds to the required gold-plated contact finish rather than tin or other alternatives. Confirm the 27-position count matches the target circuit density. Ensure the through-hole footprint aligns with the PCB layout specifications. Check that the PA 4.6 insulation rating meets the operational temperature requirements of the final assembly environment.

Headers, Male Pins Selection Notes

Select this component when a durable, gold-finished header is required for standard 2.54 mm spacing applications. The PA 4.6 material offers superior thermal performance compared to standard nylons. Consider the 3 A current rating for power distribution needs within the signal line constraints. The straight through-hole configuration simplifies automated assembly processes.

Headers, Male Pins Part Context

This part belongs to the SL 11 190 series of Fischer Elektronik pin headers. The series offers various position counts and contact finishes to suit different circuit densities. The SL 11 190 27 G specifically addresses mid-density connection needs with enhanced surface treatment for longevity.

Headers, Male Pins Replacement Considerations

Direct substitutes include SL 11 190 27 S, which shares identical mechanical dimensions but uses a tin contact finish instead of gold. Verify if the tin finish meets the environmental and conductivity requirements of the application before swapping.
