Unparalleled Details
Contact Materials: The contacts of Hongfa Magnetic Holding Relays are manufactured from high-purity silver-based alloys (such as AgSnO2 or AgNi) engineered to maintain electrical conductivity ≥ 85% IACS under frequent high-current switching, minimizing contact resistance and arc erosion.
Terminal Connections: Terminal pins and connectors for Hongfa Industrial Relays are fabricated from C1100 ETP copper, precision-machined for secure insertion fit, and finished with a 3 – 5 μm tin or nickel electroplated layer to pass 48-hour salt spray corrosion resistance standards.
Armature and Yoke: The armature and yoke assemblies within the Hongfa Power Relay utilize high-permeability magnetic steel cores (such as DT4C pure iron) subjected to vacuum magnetic annealing to ensure efficient electromagnetic conversion and stable mechanical switching response times.
Housing and Enclosure: The exterior shell of Hongfa Latching Relays utilizes flame-retardant engineering thermoplastics (UL94 V-0 rated) that seal internal metal components against dust ingress, humidity, and mechanical vibration stress in industrial environments.
