HRS DF33C-6RS-3.3

Product Overview

The DF33C Series connectors are compact, 3.3mm pitch connectors designed for internal power sources. They offer a robust 5A current capacity with 20 AWG wire and feature a secure outer locking mechanism to prevent accidental unmating. Key advantages include accurate board placement via guide posts, support for resin sealing up to 6.5mm, and prevention of short circuits through an enclosed contact design. These connectors ensure easy mating with a clear tactile click and provide excellent contact retention, especially when used with an optional retainer. They are suitable for applications demanding high reliability, such as automotive environments.
