HF5F-5-ZSTF Super-Mini Sugar Cube Sealed Relay 5VDC SPDT 6A PCB Relay

The HF5F-5-ZSTF relay from Hongfa is a compact medium-power super-mini "Sugar Cube" sealed relay designed for reliable switching in industrial electronics, embedded systems, appliance controls, security equipment, and compact PCB applications. Its small footprint and durable sealed construction make it ideal for modern high-density circuit designs.

This relay features a Form 1C (SPDT / 1c/o) contact configuration, allowing flexible switching between normally open and normally closed circuits for versatile control applications. The 5VDC coil with 55 resistance provides stable low-voltage operation, making it suitable for microcontroller systems, logic-level control circuits, and low-power electronic devices.

The HF5F-5-ZSTF supports switching loads up to 6A/5A at 250VAC or 28VDC, with a maximum switching voltage of 277VAC/28VDC. This makes it suitable for switching lighting circuits, small motors, power supplies, alarm systems, timers, HVAC controls, and industrial automation equipment.

Its sealed enclosure protects the internal contacts from dust, moisture, and solder flux contamination, improving operational reliability and extending service life. Designed with Class F insulation and capable of operating in ambient temperatures up to 105 C, this relay delivers dependable performance in demanding thermal environments.
