Technical Specifications

Key Features & Performance Advantages

Gold Plated Design for Superior Signal Integrity

The DF3 series gold plated crimp contacts feature a meticulously applied gold plating layer that delivers ultra-low contact resistance, excellent oxidation resistance, and stable electrical performance, even in harsh industrial environments with high humidity and corrosive elements. Beyond standard connectivity, this terminal boasts a maximum withstand voltage of 650V and maintains a contact resistance strictly below 30.0 mΩ. This specific electrical profile provides the ultimate safeguard for stable signal transmission in low-voltage, micro-current scenarios. By preventing surface oxidation over extended periods, the gold finish eliminates signal degradation and intermittent connection faults, ensuring data integrity in critical precision electronics.

Wide Compatibility & Flexible Design-In

This 24-28AWG industrial electronics contact is fully compatible with fine gauge wires, offering maximum flexibility for compact and high-density electronic device design. It perfectly adapts to UL 1061 and UL 1007 standard wires with an insulation outer diameter ranging from 0.75mm to 1.45mm. The precision crimp barrel structure ensures a secure, strain-relieved connection to the wire core and insulation, guaranteeing consistent mechanical pull force and electrical uniformity across every single termination. This consistent crimp geometry supports automated crimping applicators, accelerating production throughput and minimizing material waste during large-scale manufacturing runs.

High Durability for Industrial & Precision Applications

Manufactured from specialized high-grade phosphor bronze, the HRS DF3-2428SCFC offers exceptional mechanical elasticity, fatigue resistance, and vibration tolerance. During assembly, operators will notice a distinct, tactile snap-in feedback confirming proper seating within the housing. It ensures stable performance through repeated mating cycles and long-term operation. Its wide operating temperature range from -55℃ to +105℃ adapts to extreme thermal fluctuations found in industrial control panels, medical diagnostic machines, and outdoor telecommunications equipment. This thermal resilience, combined with the material's innate spring characteristics, meets the strict reliability demands of precision electronic applications where failure is not an option.
