HF152FD-24-1ZPSFQ 24VDC High Power Sub-Mini Sealed Relay 17A 105 C

The HF152FD-24-1ZPSFQ High Power Sub-Mini Sealed Relay from Hongfa is a long-endurance industrial-grade relay designed for reliable high-current switching in demanding electrical and electronic systems. Built with a Form 1C (1c/o) contact configuration and double PCB pin layout, it delivers stable mechanical support, secure PCB mounting, and consistent performance in compact control designs.

Engineered for durability and thermal stability, this relay operates with a 24VDC coil (1600 resistance) and supports switching loads up to 17A at 277VAC, with a maximum switching voltage rating of 400VAC. Its Class F insulation system and 105 C operating capability make it suitable for high-temperature environments where long-term reliability is critical.

The sealed construction protects the internal contact system from dust, moisture, and contamination, significantly extending service life and ensuring dependable operation in industrial and commercial applications. The use of AgNi contact material enhances arc resistance and electrical endurance under repeated switching cycles.

With its sub-mini footprint, the HF152FD-24-1ZPSFQ is ideal for high-density PCB layouts where space efficiency and high performance are both required. It is widely used in industrial automation, HVAC systems, power supplies, smart appliances, and control modules that require robust switching capability in a compact form factor.
