Common Precautions
Miniature Power Sealed Relays
MYQ/MYH
Sealed relays that are tough in
environments where dust or corrosive
gases, etc., are present
• Plastic sealed relays (MYQ) and hermetically sealed relays
(MYH) that are resistant to effects from the surrounding
environment
• Highly airtight structures that are tough in environments where
corrosive gases such as chloride gas, sulfuric gas, and silicone
gas are generated. They are also resistant to environments
where salt damage is occurred and where dust is generated.
• Prevent relay contact failures via a highly airtight structure.
Features
Highly Airtight Relays (Plug-in Terminals)
Plastic Sealed Relays: MYQ
These realize excellent reliability even in environments where salt damage occurs or where dust is generated.
Hermetically Sealed Relays: MYH
These realize excellent reliability even in environments where dust is generated or where corrosive gases (chloride gas, sulfuric gas, silicone gas,
etc.) are present.
Refer to the standards certifications and compliance section of your
OMRON website for the latest information on certified models.
Refer to Safety Precautions on pages 55 to 56 and Safety
Precautions for All Relays.

Features
Sealing with metals, the glass case and base, etc. with inert gases (N2) inside
makes it airtight structure which provides the external casing with durability
against harmful corrosion, and prevents corrosive gases from intruding inside
relays.
Structure that seals relays with the resin case and cover, etc., to prevent effects
from corrosive environments.
Relays in the case realize the structure that protects them from contact with
foreign materials.
