Model: HK19FDC9VSHG (also listed as HK19F DC9V SHG, HK19FDC9VSHG) Pack: 30 pieces Key specifications: 9V DC coil, 2A contact rating, 8pin What this product does and why it helps Readytouse 8pin relays with a 9V DC coil and 2A switching capability, supplied in a bulk pack of 30. Ideal when you need multiple identical relays for repairs, production runs, or larger prototype builds. Solves partsourcing delays by providing a consistent batch of the exact model you need. Saves time and cost versus ordering single units. Compact 8pin footprint works with standard PCB relay sockets and common PCB layouts, making installation straightforward and predictable. Key benefits Reliable replacement parts: Use the HK19FDC9VSHG to worn or failed relays without redesigning the board. Bulk value: 30 pieces in one pack reduce perunit cost and simplify inventory for small manufacturing or hobby projects. Easy integration: Standard 8pin format fits common sockets and PCB footprints, enabling fast swaps or upgrades. Main attributes Model: HK19FDC9VSHG (consistent model identification across the pack) Coil voltage: 9V DC — designed to operate with a stable 9V DC drive Contact rating: 2A — suitable for low to moderatecurrent switching tasks Pin count: 8pin — compatible with common 8pin relay sockets and PCB layouts Quantity: 30PCS — uniform set for multiple replacements or installations Suggested applications and use cases Electronic repairs and maintenance: defective relays in consumer electronics, control panels, or legacy equipment that use a 9V relay coil. Prototyping and small production runs: Equip multiple prototypes or small batches with identical relays to ensure consistent behavior across units. Hobby and automation projects: Integrate with microcontrollerbased systems (Arduino, Raspberry Pi with appropriate driver circuitry) to switch lights, small motors, solenoids, or other lowcurrent loads. Installation and usage tips Verify 9V DC coil supply and correct polarity where applicable. Use a driver transistor or relay driver IC if controlling from a microcontroller. Confirm the pinout against your PCB or socket before soldering or plugging in. For inductive loads, add recommended suppression (flyback diode, snubber, or RC network) to protect the driving circuit. Ordering and compatibility note This listing is for HK19FDC9VSHG relays, 9V coil, 2A rating, 8pin, quantity 30. Confirm this model and ratings match your application before . Carefully check your device's relay specifications and pinout to ensure full compatibility with the HK19FDC9VSHG before installation.
