M20-8772542

Headers, Male Pins Overview

The M20-8772542 is a surface-mount pin header assembly from the Harwin M20 series, designed for board-to-board or cable connections. It features a 2.54mm pitch with 50 positions arranged in a single row. The connector utilizes square male pins made of brass with gold plating on the mating interface and tin plating on the tail. Constructed with black polyamide (PA6T) insulation, it supports a rated current of 3A per contact and a voltage of 250V. The component operates within a temperature range of -40°C to 105°C and meets UL94 V-0 flammability standards.
