M20-7831242

Overview

The M20-7831242 is a rectangular connector receptacle from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features a 24-position female socket configuration arranged in two rows with a 0.100-inch (2.54mm) pitch. The component utilizes through-hole mounting and offers a rated current of 3A and a voltage rating of 1000V. Operating temperatures range from -40°C to +105°C. The housing is constructed from black polyamide (PA6T), meeting UL94 V-0 flammability standards, while contacts are made of phosphor bronze with gold plating.

Feature Summary

• High-voltage capability up to 1000V for robust electrical isolation
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• UL94 V-0 rated polyamide insulation provides fire resistance
• Through-hole termination supports secure PCB integration

Applications

• Industrial control systems requiring high-voltage isolation
• Telecommunications equipment interfaces
• General-purpose board-to-board interconnections
• Cable stacking assemblies in electronic modules

Procurement Notes

Verify part authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status as required by project specifications. Ensure storage conditions maintain contact integrity before installation. Cross-reference ordering suffixes to verify exact plating and packaging configurations. Validate that the received components match the specified 24-position layout and pitch dimensions.

Selection Notes

Select this component when high-voltage isolation is critical for the application. The 2.54mm pitch ensures compatibility with standard through-hole assembly processes. Consider the 1000V rating for environments requiring enhanced dielectric strength. Verify mechanical stack height requirements against the 11.04mm or 12.63mm options available within the series. Ensure the operating temperature range meets environmental constraints.

Part Context

This receptacle belongs to the Harwin M20 series, which specializes in 2.54mm pitch connectors. The series is engineered for demanding industrial and telecommunications sectors. It complements matching header assemblies to form complete interconnection solutions. The design emphasizes reliability and high-voltage performance in compact form factors.

Replacement Considerations

Direct substitutes include other M20 series variants with compatible pin counts and pitches. Verify mating header specifications to ensure mechanical and electrical alignment. Check alternative manufacturers offering equivalent 2.54mm through-hole sockets if supply constraints exist.
