Pack of 5 HF115FQ series power relays designed for reliable current switching. This set includes the HF115FQ relay variants with coil voltages 5V, 12V, 24V and 48V and a 20A contact rating. Key benefits current switching capability: 20A contact rating lets you control heavy loads without bulky mechanical switches. Flexible coil voltage options: models available for 5V, 12V, 24V and 48V control circuits so you can choose the relay that matches your system. Simplifies design and maintenance: electromechanical relays provide straightforward, proven switching for power and control circuits. Versatile and reliable: suitable for many common control and power applications where robust on/off switching is required. What this product does Functions as a power relay to switch loads using a lowvoltage control signal. The HF115FQ series models in this pack each have a coil rated for one of the listed voltages and a contact rating of 20A, enabling control of highercurrent circuits from standard control voltages. Key attributes Models included: HF115FQ0051H (5V), HF115FQ0121H (12V), HF115FQ0241H (24V), HF115FQ0481H (48V). Pack quantity: 5 pieces. Coil voltages: 5V, 12V, 24V, 48V (matched to model numbers). Contact rating: 20A. Purpose: power relay for switching and control applications. Form factor: HF115FQ series relay package (refer to manufacturer datasheet or product photos for footprint and pinout). Typical applications / use cases Automotive and vehicle systems: control lights, auxiliary pumps, fans or other accessories from standard vehicle control voltages (select the matching coil voltage). Industrial control panels and machinery: switch motors, solenoids or heating elements where a 20Arated relay is required. Building automation and power control: lighting circuits, HVAC control, or other current circuits driven from control logic or PLC outputs. Integration and safety tips Always use the relay model with the coil voltage that matches your control circuit to avoid coil damage. Verify that the load current does not exceed the 20A contact rating. Use appropriate fusing or circuit protection when switching inductive or inrush loads. Consult the relay datasheet or product images for exact pinout, mounting, and mechanical dimensions before PCB or panel integration.
