M20-7860442P

Overview

The M20-7860442P is a surface mount receptacle connector from the Harwin M20 series. It features 4 positions with a 0.100 inch (2.54mm) pitch. The connector utilizes gold-plated contacts and a black polyamide insulation body rated UL94 V-0. Designed for board-to-board applications, it supports a mating stack height of 10.04mm or 11.63mm. The unit operates within a temperature range of -40°C to 105°C and carries a current rating of 3A per contact.

Feature Summary

• Surface mount design with bottom or top entry capability
• Gold-plated phosphor bronze contacts for reliable signal transmission
• UL94 V-0 flammability rating for enhanced safety compliance

Applications

• Board-to-board interconnections in compact electronic assemblies
