3V 5-Pin Subminiature Electromagnetic Power Relay

Product Overview

The 3V 5-Pin Electromagnetic Relay is a compact, high-reliability electromechanical switching device designed for seamless integration into low-voltage control systems and microcontroller-based projects. By utilizing a 3V DC control signal, this relay allows for the safe switching of higher-voltage and higher-current loads, serving as a critical interface between sensitive electronics (like logic circuits) and external powered devices.

Featuring a standard 5-pin terminal configuration, this relay offers versatile contact arrangements (typically SPDTSingle Pole Double Throw), allowing for both Normally Open (NO) and Normally Closed (NC) switching logic. Its subminiature form factor makes it an ideal selection for space-constrained PCB layouts, automated control nodes, and battery-powered portable hardware where low-voltage trigger signals are standard.

Key Features

• Low-Voltage Trigger Compatibility: Specifically engineered to actuate with a 3V DC input, making it perfectly suited for direct integration with 3.3V logic systems such as ESP32, ARM-based microcontrollers, and modern IoT sensor hubs.

• Versatile 5-Pin Configuration: Provides a standard terminal layout that supports SPDT switching logic, offering flexibility for both load-energize and load-de-energize applications.

• Subminiature Footprint: Optimized for dense circuit board assembly, ensuring excellent performance without occupying significant real estate within small enclosures or project boxes.

• High-Isolation Switching: Provides robust electrical isolation between the low-voltage control coil and the high-voltage load circuit, protecting delicate components from feedback or surges.

• Durable Electromagnetic Core: Built with high-quality coil windings and silver-alloy contact points to ensure consistent switching performance and long operational lifespans under rated load conditions.

Technical Specifications

Applications

The go-to switching component for modern low-voltage electronics and industrial automation:

• Microcontroller Interface: Essential for controlling high-power lights, motors, or solenoids from 3.3V logic pins on microcontrollers like ESP32, STM32, or Raspberry Pi.

• IoT & Home Automation: Serves as the primary switching element in smart plugs, connected relay modules, and automated remote-switching nodes.

• Battery-Operated Control: Ideal for portable electronics where the available power supply is restricted to 3V or 3.3V rails.

• Industrial Sensor Hubs: Acts as a reliable interface component for triggering localized high-load signals based on sensor data inputs (temperature, motion, or proximity).
