Hirose DF51K Series 28-Pin Mating Connector Set | 2.0mm Pitch Wire-to-Board (Header & Receptacle)

Product Description

Create a secure, fail-safe connection for your high-density electronic assemblies with the Hirose DF51K Series 28-Pin Mating Set. This bundle includes both the straight PCB pin header [DF51K-28DP-2DSA(800)] and the matching crimp receptacle housing [DF51K-28DS-2C(800)].

Designed for demanding industrial, automotive, and robotics applications, this 2.0mm pitch wire-to-board system features Hirose’s robust center-lock design. The intuitive locking mechanism provides a clear tactile click upon mating, preventing accidental disconnections even in high-vibration environments. Together, they offer a space-saving footprint without compromising on power, signal integrity, or reliability. (Note: Crimp contacts for the receptacle housing are sold separately).

Key Features

• Complete Mating Solution: Includes both the male PCB header and the female cable-mount receptacle housing for a perfect fit.

• Secure Center Lock: The robust latching mechanism delivers exceptional retention force and a satisfying tactile "click" to ensure a positive, fully seated connection.

• Space-Saving & High-Density: 28 connections neatly organized in a compact 2.0mm pitch, dual-row footprint to save valuable PCB real estate.

• Vibration Resistant: Engineered to resist cable wrenching and mechanical stress, making it ideal for harsh environments.

• Durable & Safe: Both components are constructed from rugged, UL94 V-0 flame-retardant black PBT and are rated for extreme temperatures (-55°C to +105°C).

• Error-Proofing: Polarized housings with guide keys prevent incorrect mating
