This product is a set of 5 pieces of MY4 HH54P MY4NGS electromagnetic relays. Key features - 4PDT configuration: 4 Poles Double Throw, enabling switching of four separate circuits with a single relay. - 14-pin package: compact and ready for standard mountings. - Wide voltage compatibility: suitable for both AC and DC power supplies with coil voltages including 6V, 12V, 24V, 36V, 48V, 110V, 220V, and 380V. - Power relay capability: designed for use as a power relay; models such as MY4NJ are available in this range. - Specific pack detail: this set includes 5 pcs of MY4NJ relays for AC operation at 6V. Benefits - Flexible control: handle multiple circuits with one relay, reducing wiring complexity in control panels and automation setups. - Wide application range: supports a broad set of voltages, enabling use across various equipment and systems that require reliable switching. - Durable and compatible: designed to work as a power relay within the MY4 family, ensuring compatibility with common relay footprints and mounting schemes. - Ready for AC operation at 6V: the pack is specified for AC operation at 6V, providing a ready-to-use option for that configuration. Technical details to consider - Poles and throws: 4PDT (four poles, double throw) for switching multiple circuits. - Pin count: 14 pins, suitable for standard relay sockets or PCB mounting. - Brand/model family: MY4, with reference to MY4NJ as an available model within the same family. Use scenarios - Industrial control panels: drive four separate circuits from a single control signal, enabling centralized automation without multiple relays. - Motor or heater control systems: isolate and switch multiple loads with one device, improving safety and reliability in control logic. - Home automation or lab projects: create compact, multi-channel switching for lighting, fans, or experimental circuits, with compatibility across common coil voltages. Note - The pack specifies 5 pieces of MY4NJ relays for AC operation at 6V, and the product line references MY4 HH54P MY4NGS variants. Ensure the selected coil voltage matches your system requirements for safe and reliable operation.
