The HF152FD-5-1ZPSFQ High Power Sub-Mini Sealed Relay from Hongfa is a long-endurance, high-current switching relay designed for compact yet demanding electrical and electronic applications. With a Form 1C (1c/o) contact configuration and a double PCB pin layout, it delivers strong mechanical stability, reliable PCB mounting, and consistent switching performance in high-density circuit designs.

This model operates with a 5VDC coil (70 resistance), providing efficient low-voltage actuation while maintaining strong switching capability up to 17A at 277VAC. It is rated for a maximum switching voltage of 400VAC, making it suitable for a wide range of industrial and power control applications requiring robust AC load handling.

Built with Class F insulation and engineered for operation in environments up to 105 C, the relay is optimized for thermal stability and long operational life under continuous load conditions. Its sealed construction protects internal contacts from dust, moisture, and environmental contaminants, significantly improving durability and reliability in harsh operating environments.

The AgNi contact material enhances arc resistance and electrical endurance, ensuring stable performance under repeated switching cycles and inductive loads. The sub-mini footprint allows integration into compact PCB layouts where space efficiency and high performance are both critical.
