SRD-5VDC-SL-C Relay 5V DC Coil, 10A, SPDT, 220VAC, 5 Pin

Relay 5V DC Coil, 10A, SPDT, 220VAC, 5 Pin, SRD-5VDC-SL-C

Product Overview

The SRD-05VDC-SL-C from Pro Tronix is the most popular choice for makers and engineers working with 5V logic systems. Because its coil operates at 5V DC, it can be powered directly from the same power rail as your microcontroller, making it the standard component for smart home prototypes, IoT devices, and school robotics projects.

This SPDT (Single Pole Double Throw) relay acts as an electrically operated switch. It uses a small amount of power to move an internal armature, which can then toggle a much larger load—up to 10A at 250V AC. Whether you are building an automated lamp, a web-controlled power strip, or a temperature-controlled heater, this “Sugar Cube” relay is the essential bridge between low-power code and high-power reality.

Technical Specifications

Key Features
