HF105F-2-012D-1HSTF High Power Sealed Relay 12V 40A PCB Form 1A

The hf105f-2-012d-1hstf is a high-power sealed pcb relay engineered for demanding switching applications requiring high current handling and dependable operation. Featuring a form 1a (spst-no) contact configuration, this relay is ideal for industrial, automotive, and power control systems.

Designed with a 12vdc coil and 155 coil resistance, this relay provides fast and stable switching performance while maintaining efficient coil power consumption. Its robust internal contact system supports heavy-duty load switching up to 40a at 240vac or 28vdc, with maximum ratings reaching 40a at 277vac.

The relay includes 6.3mm recessed fast-on terminals combined with pcb mounting capability, allowing secure high-current connections and simplified installation in power control circuits. This makes it especially suitable for applications involving motors, compressors, heating systems, battery management, and industrial automation equipment.

Its sealed construction protects the internal mechanism from dust, moisture, and environmental contaminants, improving reliability and operational lifespan in harsh environments. Class f insulation enhances thermal endurance, ensuring stable performance under elevated operating temperatures and continuous heavy loads.

The form 1a (spst-no) configuration offers a simple and highly reliable normally-open switching path with low contact resistance, optimized for efficient high-current power control.
