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.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Driver Requirement: While the coil is 5V, you cannot drive it directly from a microcontroller GPIO pin. The coil draws ~70mA, which exceeds typical pin limits (~20mA). Use a transistor (like a BC547) as a driver.

  • Back-EMF Protection: Always install a flyback diode (e.g., 1N4007) across the coil terminals to prevent high-voltage spikes from damaging your microcontroller when the relay deactivates.

  • PCB Routing: When switching 250V AC on a PCB, ensure adequate "creepage" distance and use thick copper traces to safely handle the 10A current without overheating.

  • Audible Feedback: The mechanical "click" provides excellent troubleshooting feedback, confirming the coil is receiving power and the armature is moving.

Package Includes

  • 1 x 5V DC Sugar Cube Relay (SPDT)
