Description

Hongfa HF3FF/005-1ZST Subminiature Electromechanical Relay

HF3FF/005-1ZST is a 5 VDC coil relay with 1 Form C switching, PCB termination, and resistive-load contact ratings of 10 A NO and 5 A NC.

The Hongfa HF3FF/005-1ZST is a subminiature electromechanical relay for coil-operated switching. Its 5 VDC coil controls a 1 Form C contact, which provides both normally open and normally closed switching paths. The NO contact supports up to 10 A and the NC contact up to 5 A for resistive loads.

Its AgSnO2 contacts support switching, while the plastic-sealed construction and PCB termination suit board-level designs. The relay has a mechanical endurance of 10 million operations, making it a fit for repeated switching tasks.

Use this 5 V PCB relay in control systems, UPS systems, inverters, home appliances, security systems and power windows. Its single changeover contact lets a control signal switch between two circuit paths.
