5 piece relay set with three coil voltages - Includes HK19F relays in DC5V SHG, DC12V SHG, and DC24V SHG variants. - Coil voltages supplied: 5V DC, 12V DC, and 24V DC. 8-pin DPDT mini relays for PCB mounting - Each unit is an 8-pin coil DPDT relay. - Contacts: 2 normally open (NO) and 2 normally closed (NC). - Compact, suitable for direct PCB mounting in compact electronics and control circuits. Size and packaging - Compact HK19F size across the set, designed for PCB typ applications. - 8-pin package simplifies integration with standard PCB layouts. Flexible voltage compatibility for diverse circuits - The set provides multiple coil voltages, enabling flexible use in designs that require switching controlled by different DC levels. - Ideal for projects and products that mix voltage rails or require interchangeable coil options. Reliable voltage-controlled switching for PCB setups - Built for precise, dependable switching in voltage-controlled PCB applications. - Suitable for prototyping, automation, and compact control modules where two circuits need to be switched simultaneously. Practical use scenarios - Dual-load control on a PCB: Use the DPDT contacts to switch two loads or signals in tandem from a single control signal, enabling compact control of related circuits. - Prototyping and development: A convenient set for electronics hobbyists and engineers to test systems that operate at different DC coil voltages, without redesigning the PCB for a single coil type. - Polarity reversal and circuit routing for small DC motors or power paths: With DPDT contacts, you can configure simple motor reversal or route power and signal paths in a compact, PCB-mounted relay solution.
