M20-7833746

Overview

The M20-7833746 is a rectangular connector socket assembly from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features a dual-in-line configuration with 74 positions arranged in two rows. The connector utilizes a 2.54 mm (0.100 inch) pitch and employs square female contacts with gold plating for reliable signal transmission. Constructed with a black polyamide (PA6T) insulator rated UL94 V-0, it supports a current rating of 3A and a voltage rating of 1000V. The unit operates within a temperature range of -40°C to +105°C and includes a push-pull locking mechanism.

Feature Summary

• Dual-row 74-position layout with 2.54mm pitch for high-density interconnects
• Gold-plated square female contacts ensure stable electrical performance
• Push-pull locking system provides secure mechanical retention during mating
• UL94 V-0 rated polyamide insulation supports high-temperature industrial environments

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing high-pin-count interfaces
