M20-7870246

Overview

The M20-7870246 is a Harwin M20 series PCB receptacle designed for board-to-board connections. It features a 2-row configuration with 4 contacts and a 2.54 mm pitch. The connector utilizes surface mount termination and supports both bottom and top entry orientations. Constructed with polyamide insulation, it operates within a temperature range of -40°C to +105°C and carries a voltage rating of 1000V.

Feature Summary

• Dual-entry design supporting flexible board stacking configurations
• High-voltage isolation capability for industrial applications
• Compact surface-mount footprint optimized for high-density PCB layouts

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment infrastructure
• General-purpose electronic assemblies

Procurement Notes

Verify the specific orientation requirement (bottom or top entry) against your PCB layout constraints before ordering. Confirm that the 1000V rating aligns with your system's electrical specifications. Ensure compatibility with standard surface-mount reflow processes during assembly planning.

Selection Notes

Select this component when a low-profile, dual-row female header is required for rigid board-to-board interfaces. The 2.54 mm pitch ensures compatibility with standard pin headers. Consider the square contact shape for reliable mating force and signal integrity in general-purpose environments.
