Description

ALFG2PF121 Non-Latching Power Relay

The ALFG2PF121 is a high-performance, non-latching power relay from Panasonic, designed for applications requiring reliable switching of medium to high loads. It features DPDT contacts, operates on 12VDC, and offers high insulation and long electrical life. Ideal for HVAC, industrial, and energy systems.

Technical Information

  • Model: ALFG2PF121
  • Relay Type: Non-Latching Power Relay
  • Coil Voltage: 12V DC
  • Contact Configuration: DPDT (Double Pole Double Throw)
  • Contact Rating: 8A at 250V AC / 30V DC
  • Contact Material: Silver alloy
  • Dielectric Strength: 4000 Vrms (coil to contact)
  • Insulation Resistance: 1000 MΩ min (500V DC)
  • Operating Time: ≤ 15 ms
  • Release Time: ≤ 10 ms
  • Mounting Type: PCB Mount
  • Ambient Temperature Range: -40°C to +85°C
  • Dimensions: 29 mm x 13 mm x 15 mm

What is a Power Relay?

A power relay is an electromechanical switch used to control larger electrical loads using a low-power signal. Non-latching relays return to their default state when power is removed, making them suitable for safety-critical and frequently cycled systems.

Key Features

  • DPDT (2 Form C) contact arrangement
  • High insulation resistance and dielectric strength
  • Compact and PCB-mountable design
  • Non-latching type – returns to original position when power is removed
  • High contact reliability with silver alloy contacts
  • Quick operation and release times
  • UL, CSA, and VDE certified

Benefits

The ALFG2PF121 is ideal for applications that demand dependable switching of loads with enhanced safety and control. Its non-latching configuration ensures the circuit automatically opens when power is off—providing a fail-safe design. With its compact size and high-quality contact performance, this relay offers long-term reliability for both industrial and consumer electronics.

Key Benefits:

  • Safer operation due to non-latching design
  • Ideal for safety and control circuits
  • Long service life and consistent performance
  • Compact form for tight PCB layouts
  • Trusted Panasonic quality and compliance

Applications

  • HVAC systems
  • Industrial control systems
  • Renewable energy devices
  • Smart home appliances
  • Power distribution boards
  • Emergency systems and alarms

How to Use?

Install the ALFG2PF121 relay onto a printed circuit board using standard through-hole soldering. Connect the 12VDC coil terminals to the control logic or microcontroller output. When energized, the relay switches both poles; once the control voltage is removed, it returns to its default state, ensuring automatic disconnection. Ensure that current and voltage limits are not exceeded for safe and optimal operation.

Cautions

  • Avoid overvoltage or incorrect polarity on coil terminals
  • Use a flyback diode across the coil when driven by transistors
  • Prevent exposure to moisture or corrosive environments
  • Ensure mechanical shock and vibration are within rated limits
  • Disconnect power before handling or installation

Why You Should Buy

Choose the Panasonic ALFG2PF121 for projects that demand a reliable, safe, and easy-to-integrate power relay. Its non-latching behavior ensures safety in power-off conditions, while its compact design and robust construction deliver long-term performance in demanding environments.

Where and Who Uses It

  • Where: Found in HVAC systems, energy management panels, industrial machines, and control boards
  • Who: Engineers, automation professionals, HVAC technicians, OEM manufacturers
