HF105F-1-012DT-1ZS High Power Sealed Relay 12V 20A PCB Form 1C

Detailed Description
This relay operates with a 12VDC coil and a coil resistance of 155 , ensuring stable and efficient activation from standard control circuits. Its sealed horizontal design protects internal components from dust, moisture, and contaminants, improving long-term reliability in harsh environments.
The HF105F-1 series is rated for 10A continuous switching at 240VAC, with high inrush capability up to 20A at 277VAC. This makes it suitable for inductive loads such as motors, compressors, transformers, and heating systems where surge currents are present during startup.
Designed for PCB mounting, the relay offers a compact footprint while maintaining strong electrical performance. The sealed construction enhances mechanical durability and ensures consistent operation even under vibration or environmental stress.
With high voltage capability up to 277VAC, this relay is well-suited for global industrial standards. Its robust internal contact structure supports repeated switching cycles while maintaining low contact resistance for efficient power transfer.
