SL 1 025 4 S

Headers, Male Pins Overview

The SL 1 025 4 S is a male pin header connector from the Fischer Elektronik SL series, designed for surface mount or through-hole PCB integration. It features a single row with four positions and a standard 0.100-inch (2.54 mm) pitch. The connector utilizes copper-tin contacts with a gold-plated mating interface and tin-plated tails for soldering. Rated for 3 A current and 250 V AC voltage, it operates within a temperature range of -40°C to +163°C. The housing is constructed from black PA46/GF material, ensuring UL94 V-0 flammability compliance.

Headers, Male Pins Feature Summary

• Single-row male pin configuration with square contact shape for reliable board-to-board or cable connections
• Gold-plated mating surfaces ensure low contact resistance and corrosion resistance in harsh environments
• Polyamide insulation with glass fiber reinforcement provides structural stability and high thermal resistance
• Standardized 2.54 mm pitch facilitates compatibility with common PCB footprint designs

Headers, Male Pins Applications

• General-purpose electronic circuit interconnections
• Signal transmission in industrial control modules
• Prototyping and development board assemblies
• Consumer electronics internal wiring harnesses

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required termination style and plating thickness. Confirm that the component meets RoHS directives if environmental compliance is mandatory for the assembly. Ensure the selected variant aligns with the intended mounting method, whether surface mount or through-hole, as specified in the official datasheet documentation.

Headers, Male Pins Selection Notes

Select this component when a compact, single-row male header is required for low-current signal applications. The 2.54 mm pitch ensures broad compatibility with existing connector systems. Consider the operating temperature range and voltage rating to ensure suitability for the target environment. Verify mechanical retention requirements against the push-pull or standard locking mechanisms available in the series.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL 1 series, which focuses on precision-engineered PCB connectors. The series offers various row counts and pin configurations while maintaining consistent dimensional standards. The SL 1 025 4 S represents a specific four-position variant optimized for space-constrained designs requiring reliable electrical connectivity.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, single-row layout, and four-pin count. Verify that alternative headers share compatible contact materials and insulation ratings. Cross-reference mechanical dimensions to ensure fit within the designated PCB footprint without interference.
