Omron LY4 Relay

Omron LY4 Relay with a 12V DC coil is a compact general-purpose relay designed to switch electrical circuits in control panels, automation modules, and electronics projects. It belongs to Omron's LY4 family, providing a reliable interface that lets a low-voltage control signal energize the coil to open or close its contacts, thereby isolating the control side from higher-power loads. This configuration makes it suitable for signaling, interlocking, and basic load switching in industrial equipment and hobbyist assemblies where a traditional electromechanical relay is preferred for simple, robust operation. By choosing an Omron LY4 relay, you benefit from a product line known for consistent coil voltages and compatible form factors across the LY series, enabling straightforward replacement or expansion in established control schemes.
