M20-7831842

Overview

The M20-7831842 is a rectangular socket connector from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 36 positions arranged in two rows with a 2.54 mm pitch. The connector utilizes phosphor bronze contacts with selective gold and tin plating to ensure reliable signal transmission. Rated for 1000 V and 3 A, it operates within a temperature range of -40°C to 105°C. The housing is constructed from black polyamide (PA6T) nylon meeting UL94 V-0 flammability standards. It employs a push-pull fastening mechanism and supports through-hole mounting.

Feature Summary

• Push-pull fastening system for secure mechanical retention
• Selective gold and tin contact plating for corrosion resistance
• High voltage insulation rating up to 1000 V
• UL94 V-0 rated polyamide housing material

Applications

• Board-to-board interconnections
• Cable stacking assemblies
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm that the specific ordering suffix matches the required contact plating and termination style. Ensure storage conditions maintain integrity of the selective plating before assembly. Cross-reference part numbers with authorized distributors to avoid counterfeit sources.

Selection Notes

Select this model when high voltage isolation and robust mechanical locking are required. The push-pull design simplifies mating cycles compared to screw-lock variants. Verify that the 2.54 mm pitch aligns with PCB layout constraints. Consider the operating temperature range for environmental compatibility. Evaluate the contact current rating against circuit load requirements.
