M20-7893242

Overview

The Harwin M20-7893242 is a 32-position receptacle connector from the M20 series, designed for board-to-board or cable applications. It features a 2.54 mm pitch and operates within a temperature range of -40°C to 105°C. The connector has a current rating of 3A and a voltage rating of 1000V. Contacts are made of phosphor bronze with gold plating for mating surfaces and tin plating for termination. The housing is constructed from polyamide (PA6T) nylon 6T, rated UL94 V-0, and is black in color.

Feature Summary

• High voltage capability up to 1000V for robust electrical isolation
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Polyamide insulation material provides thermal stability and flame resistance

Applications

• General purpose electronic assemblies
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific contact configuration and orientation against design requirements before procurement. Confirm that the 1000V rating aligns with system safety standards. Ensure compatibility with mating headers regarding stacking height and latch mechanisms. Check for any recent product change notifications affecting material composition or dimensions.

Selection Notes

Select this component when high voltage isolation is required in compact board-to-board layouts. The 2.54 mm pitch offers standard spacing for general interconnect needs. Consider the operating temperature range and UL94 V-0 rating for environmental compliance. Verify that the 3A current capacity meets the circuit load requirements without excessive heating.

Part Context

This part belongs to the Harwin M20 series, known for versatile surface mount and through-hole options. It complements other M20 headers and sockets for complete interconnect solutions. The series supports various pin counts and orientations, facilitating flexible PCB layout designs across multiple industries.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate generic 32-position 2.54mm pitch receptacles only if mechanical and electrical parameters match exactly. Verify pinout and locking mechanism compatibility before substitution.
