HF3FA-024-ZSTF (136) Submini Relay 24VDC SPDT 10A PCB Sealed Class F

Description:
- The HF3FA-024-ZSTF(136) relay from Hongfa is a compact subminiature high-power sealed relay designed for reliable PCB switching in industrial control, appliance, and automation systems. Featuring a Form 1C (SPDT) contact configuration, it provides flexible switching between normally open and normally closed circuits, making it suitable for a wide range of signal and power control applications.
- This relay operates with a 24VDC coil rated at 1.6k and approximately 360mW coil power, delivering stable and efficient actuation for standard industrial control voltages. It is well suited for PLC systems, embedded controllers, relay driver circuits, HVAC controls, and general-purpose automation electronics.
- The HF3FA-024-ZSTF supports switching loads up to 10A at 250VAC, making it suitable for controlling motors, solenoids, lighting systems, heaters, power supplies, and other AC/DC loads in compact PCB designs. Its vertical subminiature footprint allows efficient use of space in high-density electronic assemblies.
-Built with sealed construction and Class F insulation, the relay provides strong resistance to heat, electrical stress, and environmental contamination such as dust and flux residue. It also features AgSnO contact material for improved arc resistance and longer electrical life. With UL, CUL, and VDE approvals, it meets key international safety and reliability standards.
