HRS DF51K-6DS-2C(800)
Product Overview
The DF51K Series is a 2mm pitch, positive lock, wire-to-board connector designed for reliable and secure connections. It features a positive lock mechanism that provides a clear tactile click, preventing incomplete mating. With a wide variation of straight and right-angle types, single and double row contact arrangements, and gold/tin plating options, it offers flexibility for various board designs and application needs. The connector is designed for easy lock release with a center lock lever that increases in width with pin count, enabling high-density mounting. Its visually and mechanically polarized design prevents incorrect mating. The DF51K Series is suitable for potting up to 3mm and utilizes the same crimp tools as the DF11 Series, supporting cable sizes from 22 to 30 AWG. It is UL and C-UL certified.
