12V DC Relay 5 Pin

🔹 Product Overview

The 12V DC Relay 5 Pin is an electromagnetic switching device used to control high-voltage or high-current loads using a low-voltage DC signal. It is widely used in automation, Arduino projects, home appliances, industrial controls, and power switching applications.

This relay typically follows the SPDT (Single Pole Double Throw) configuration, allowing switching between normally open (NO) and normally closed (NC) contacts.

🔹 Key Features

• Coil Voltage: 12V DC

• Contact Type: SPDT (1C – Changeover)

• Total Pins: 5

• High Switching Capacity: Up to 10A

• Compact & PCB Mountable

• Sealed Plastic Housing

• Reliable Electromagnetic Operation

🔹 Technical Specifications

• Model (Common Type): SRD-12VDC-SL-C

• Rated Coil Voltage: 12V DC

• Coil Resistance: Approx. 400Ω (varies by manufacturer)

• Contact Rating:

  • 10A @ 250V AC

  • 10A @ 125V AC

  • 10A @ 30V DC

• Contact Material: Silver alloy

• Mounting Type: Through-hole PCB

• Operating Temperature: -40°C to +85°C

🔹 Pin Configuration (5 Pin Layout)

1. 2 Pins: Coil (12V DC input)

2. 3 Pins:

   • COM (Common)

   • NO (Normally Open)

   • NC (Normally Closed)

When the coil is energized (12V applied), the contact switches from NC to NO.
