M20-7834042

Overview

The M20-7834042 is a dual-in-line (DIL) rectangular socket assembly manufactured by Harwin Inc. This component features 80 positions arranged in two rows with a standard 2.54 mm pitch. It utilizes gold-plated contacts for the interface and tin-plated termination pins for surface mount installation. The housing is constructed from black UL94 V-0 rated polyamide, ensuring flame retardancy. Designed for board-to-board or cable stacking applications, it supports a current rating of 3A and withstands voltages up to 1000V. The operating temperature range spans from -40°C to +105°C.

Feature Summary

• Dual-beam contact design enhances electrical connection reliability and mechanical stability.
• Surface mount technology (SMT) compatible bottom entry configuration for automated assembly.
• High-temperature liquid crystal polymer (LCP) housing resists thermal stress during soldering processes.

Applications

• Board-to-board interconnections in high-density electronic assemblies
• Cable stacking configurations requiring robust vertical connections
• Industrial control systems demanding reliable signal transmission

Procurement Notes

Verify the specific ordering suffix to confirm the exact plating combination and termination style required for your manufacturing process. Confirm RoHS compliance status through official datasheets before integration. Check for end-of-life notifications as this series may have obsolescence updates. Ensure compatibility with your PCB footprint dimensions and reflow profile requirements.

Selection Notes

Select this model when a high-pin-count DIL socket is necessary for SMT assembly. The dual-row layout maximizes connectivity within a compact footprint. Verify that the 3A current rating meets the load requirements of the target circuit. Consider the 1000V voltage rating for insulation needs in high-potential environments.
