Omron MY3 Series Power Relay, 120V Coil Voltage, 3PDT Contact Configuration - MY3N 110/120VAC


This power relay is a Compact electromechanical switching device designed for control and signal applications in industrial environments. It operates from an AC Coil and provides multiple changeover contacts to manage circuits requiring separation or interlocking. The relay is suitable for panel or socket mounting where secure, removable connections are needed.

Features and Benefits:


• 120VAC Coil draws low power 1.1W for energy-efficient operation
• Three-pole double-throw contacts enable complex switching arrangements
• Silver contact material minimises contact wear and maintains low resistance
• Switching capability of 125V at 5A allows moderate power control
• Coil resistance of 4430Ω supports predictable Coil drive characteristics

Applications


• Suitable for automation control cabinets requiring multiple contact paths
• Ideal for electrical control panels that need plug-in replacement parts
• Used with industrial controllers to switch moderate AC or DC loads
• Can be used for machinery interlocks where Compact multi-contact relays are required

What Terminal arrangement does it use for installation?


It employs a plug-in Terminal format that allows easy insertion into sockets for fast replacement and secure electrical connection.

What temperature range can it tolerate in service?


The relay is rated to operate between -55°C and 60°C, supporting use in a wide variety of ambient conditions.

How is contact performance quantified electrically?


Contact resistance is specified at 50mΩ and the switching power rating is 120W, indicating its capability for moderate-power circuit switching.

Which approvals confirm its suitability for industrial use?


It carries standard approvals from UL and CSA, indicating compliance with common North American safety standards.

What mechanical envelope should installers allow for?


The unit measures 36mm wide, 21.5mm long and 28mm high, which assists in planning panel space and socket compatibility.
