Omron LY4F Series Power Relay, 120V AC Coil Voltage, 10A Switching Current - LY4F AC120


This power relay is a Compact electromechanical switching device designed for control and signal tasks in industrial systems. It operates from an alternating Coil supply and offers multiple changeover contacts for complex switching schemes, making it suitable for automation panels and electronic control assemblies where robust switching of AC and DC loads is required.

Features and Benefits:


• 120V AC Coil consuming 2.5W for standard mains-driven control
• 4430Ω Coil resistance for predictable Coil current draw
• Four-pole double-throw contact set enabling multiple circuit control
• Silver-alloy contacts delivering low contact resistance of 50mΩ
• Rated switching current of 10A to handle moderate power loads
• PCB pin terminals for direct printed circuit board mounting

Applications


• Suitable for automation control panels requiring multi-circuit switching
• Ideal for industrial control relays in electrical distribution modules
• Used for switching moderate AC and DC loads in machinery control
• Can be used for signal routing in complex electronic systems

What temperature range can it operate within?


It is specified to function between -25°C and 55°C, accommodating typical indoor industrial environments.

How is it mounted to a PCB or assembly?


The relay uses PCB pin terminals and a case surface-mount style for secure board-level installation.

Which contact materials affect contact longevity and conductivity?


The contacts are MADE from a silver alloy, chosen for low resistance and good conductivity under switching conditions.

What approvals support its use in regulated systems?


It holds both UL and CSA approvals, indicating conformity with recognised safety standards.

What switching voltage and power ratings apply to loads?


It is rated for switching at up to 125V AC and 125V DC with a switching power parameter of 1.5W.

Approvals

VDE, UL, CSA, TUV
