HFE62-5-1HST-L2 5V 2-Coil Latching SPST-NO Relay 10A PCB

The HFE62-5-1HST-L2 is a medium-power miniature sealed double-coil latching relay designed for applications requiring energy-efficient bistable operation, reliable high-current switching, and compact PCB integration. Featuring a Form 1A (SPST-NO / normally open) contact configuration, this relay is ideal for ON/OFF load control in industrial automation, smart energy systems, embedded electronics, automotive modules, and general-purpose power switching applications.

Operating with a 5VDC coil voltage and dual 89 / 89 coils, the relay uses a two-coil latching mechanism with separate SET and RESET coils. This design allows the relay to maintain its last switched state without continuous coil power, significantly reducing energy consumption and heat generation. It is especially suitable for battery-powered systems and low-power control designs where energy efficiency is critical.

The relay supports a robust electrical rating of 10A at 250VAC and 30VDC, enabling reliable switching of medium- to high-power AC and DC loads. Its SPST-NO contact configuration provides straightforward ON/OFF control for motors, lighting systems, solenoids, heating elements, and other electrical devices requiring dependable switching performance.

The sealed miniature housing protects internal components from dust, solder flux, moisture, and other environmental contaminants. This ensures long-term reliability and stable operation in industrial, automotive, and commercial environments where durability is essential. Its compact footprint also makes it ideal for high-density PCB layouts.

Designed for PCB mounting, the relay integrates easily into automated assembly processes and modern electronic manufacturing systems, supporting efficient and scalable production.

The latching mechanism also provides the advantage of maintaining state during power interruptions, making it useful in memory-based or state-retaining control systems.
