MY4N220/240VAC

Overview of Omron MY4N220-240VAC

The Omron MY4N220-240VAC is a miniature power relay with a 4PDT (4-pole double throw) contact configuration. Designed for industrial applications, it features a coil rated for 220-240 VAC operation and offers a maximum contact current of 3 A for both AC and DC loads. It utilizes Au clad and silver alloy contacts to reduce contact resistance and improve reliability. The relay comes with a plug-in terminal structure and an LED indicating coil operation for easy status monitoring.
