5V DC Relay 5 Pin

🔹 Product Overview

The 5V DC Relay 5 Pin is an electromagnetic switching device that allows a low-voltage 5V signal (from Arduino, microcontroller, or logic circuit) to control higher voltage and higher current loads safely. It is widely used in automation systems, embedded projects, and electronic switching applications.

This relay typically uses an SPDT (Single Pole Double Throw) configuration, providing Normally Open (NO) and Normally Closed (NC) switching options.

🔹 Key Features

• Coil Voltage: 5V DC

• Contact Type: SPDT (1C Changeover)

• Total Pins: 5

• High Switching Capacity: Up to 10A

• PCB Mountable Design

• Compact & Durable Plastic Housing

• Reliable and Long Operating Life

🔹 Technical Specifications

• Common Model: SRD-05VDC-SL-C

• Rated Coil Voltage: 5V DC

• Coil Resistance: Approx. 70Ω (varies by manufacturer)

• Contact Rating:

  • 10A @ 250V AC

  • 10A @ 125V AC

  • 10A @ 30V DC

• Contact Material: Silver alloy

• Mounting Type: Through-hole PCB
