HF3FA-024-HSTF (136) Sugar Cube Relay 24VDC SPST-NO 10A Sealed PCB Relay

Description:
- The HF3FA-024-HSTF(136) relay from Hongfa is a compact high-power sub-miniature "Sugar Cube" sealed relay designed for reliable switching in PCB-mounted control systems. With a Form 1A (SPST-NO) contact configuration, it is intended for straightforward on/off control of AC and DC loads in industrial, appliance, and automation applications.
- This version uses a 24VDC coil rated at 1600 , providing efficient actuation for standard industrial control voltages while maintaining low coil power consumption. It is well suited for PLC outputs, control boards, embedded systems, and power switching interfaces where stable and consistent relay response is required.
- The HF3FA-024-HSTF supports a rated switching capacity of 10A at 250VAC, with an extended capability up to 15A under specific conditions. It can handle up to 277VAC or 28VDC maximum switching voltage, making it suitable for a wide range of electrical loads including motors, solenoids, heaters, lighting systems, and power supplies.
- It's sealed "Sugar Cube" construction protects internal contacts from dust, flux residue, and environmental contamination, significantly improving long-term reliability and switching stability. Built with UL94 V-0 flame-retardant materials and Class F insulation, it offers strong thermal endurance and high electrical safety margins for demanding applications.
