SL 11 190 31 G

Headers, Male Pins Overview

The SL 11 190 31 G is a single-row male header connector manufactured by Fischer Elektronik. It features a 2.54 mm (0.100 inch) contact pitch and contains 31 positions. The contacts are constructed from copper-tin alloy with a gold plating finish on the mating section, providing reliable conductivity. The insulating body is made of glass-filled polyamide PA46, rated for an operating temperature range of -40°C to 163°C. This through-hole component supports a nominal current of 3 A and a nominal voltage of 250 V AC, with a test voltage rating of 2000 V.

Headers, Male Pins Feature Summary

• Gold-plated male pins ensure stable signal transmission and corrosion resistance in demanding environments.
• Glass-filled polyamide insulation provides high thermal stability and mechanical strength.
• Through-hole mounting design offers secure PCB attachment for robust electrical connections.

Headers, Male Pins Applications

• General-purpose board-to-board interconnections
• Wire-to-board assembly applications
• Industrial control system circuit boards

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and material composition against the official datasheet before procurement. Confirm that the glass-filled PA46 insulation meets the thermal requirements of your application environment. Ensure the through-hole footprint matches the manufacturer's recommended land pattern to guarantee proper soldering integrity and mechanical retention during operation.

Headers, Male Pins Selection Notes

Select this model when a single-row male header with gold contacts is required for high-reliability applications. The 31-position count fits designs needing this specific channel density. Consider the 2.54 mm pitch compatibility with existing mating connectors. Evaluate the -40°C to 163°C operating range against environmental conditions. Verify that the unshrouded design aligns with the assembly constraints and alignment needs of the target product.

Headers, Male Pins Part Context

This component belongs to the SL 11 190 series of Fischer Elektronik headers. The series offers various pin counts and contact finishes to suit different electrical and mechanical requirements. The 'G' suffix typically denotes gold plating, distinguishing it from tin-plated variants like the 'Z' series. These connectors are designed for standard industrial and commercial electronics where durability and consistent performance are critical.

Headers, Male Pins Replacement Considerations

The SL 11 190 31 Z is a direct alternative within the same series, differing primarily in contact finish (tin vs. gold). Ensure the change in plating material does not affect corrosion resistance requirements or mating cycle expectations. Other series members may vary in row count or pitch; verify dimensional compatibility before substitution.
