HRS DF33C-2RS-3.3
Product Overview
The DF33C Series is a 3.3mm pitch connector designed for internal power sources, offering a compact size with a 5 Amp capacity when used with 20 AWG wire. It features a secure outer locking mechanism to prevent accidental unmating, guide posts for accurate board placement, and supports resin sealing up to 6.5mm. The design includes short circuit prevention through an enclosed contact housing and offers excellent contact retention with an optional retainer. It is suitable for applications demanding high reliability, such as automotive, and provides an easy mating operation with a clear tactile click.
