Product Description

The 5V Sugar Cube Relay is a compact electromechanical switch designed specifically for low-voltage automation and control systems. Operating at a 5V coil voltage, it is the premier choice for developers working with Arduino, ESP32, and Raspberry Pi logic controllers. This SPDT (Single Pole Double Throw) relay allows for the switching of high-power circuits between two output states, making it a critical component for DIY smart home projects, automated irrigation systems, and various IoT industrial applications. Its miniature "sugar cube" footprint ensures it occupies minimal space on a PCB while handling significant electrical loads.

Detailed Key Features

  • Microcontroller Compatible: Optimised for 5V logic systems, simplifying power delivery from standard development board voltage rails.

  • High-Load Switching: Despite its small size, it safely manages loads up to 10A at 250V AC, suitable for lighting, solenoid valves, and small motors.

  • Flexible Logic Configuration: Includes Common (COM), Normally Open (NO), and Normally Closed (NC) pins for versatile "on-default" or "off-default" circuit designs.

  • Durable Silver Alloy Contacts: Engineered to resist pitting and contact welding, ensuring reliable operation over thousands of mechanical cycles.

  • Industry Standard Layout: Features a standard 5-pin layout that fits breadboards (via adapters) and standard PCB footprint libraries.

All Technical Details

  • Coil Resistance: Approximately 70Ω to 100Ω depending on the specific batch.

  • Power Consumption: Efficient coil design consuming roughly 0.36W during activation.

  • Dielectric Strength: 750V AC between open contacts, providing a high level of electrical isolation.

  • Release Time: Rapid release of ≤ 5ms for responsive system control.

  • Physical Dimensions: Compact casing measuring ~19.5mm x 15.5mm x 15.5mm.

  • Contact Material: High-conductivity silver alloy for reduced contact resistance.

Product Description

This SPDT (Single Pole Double Throw) relay features five pins: two for the coil and three for the switching contacts (Common, Normally Open, and Normally Closed). When 5V is applied to the coil, the internal electromagnet pulls the contact from the NC position to the NO position. Its robust design is capable of handling up to 7A at 250VAC, making it suitable for controlling lights, fans, and small motors.

Key Features

  • Compact Size: The "Sugar Cube" design (approx. 19x15x15mm) is optimized for high-density PCB layouts.

  • Low Coil Power: Efficiently triggered by standard 5V logic, though a driver circuit (transistor/optocoupler) is required for microcontroller use.

  • Sealed Construction: The plastic housing protects the internal contacts from dust and oxidation, ensuring a long mechanical life.

  • Versatile Switching: Being an SPDT relay, it can be used to either turn a device ON/OFF or switch between two different power paths.

  • Fast Response: Features an operating time of under 10ms, providing quick switching for responsive automation.
