➋ Selecting Relays
➀ Mounting Structure and Type of Protection
➋-➀-1 Type of Protection
If a Relay is selected that does not have the appropriate type of
protection for the atmosphere and the mounting conditions, it may
cause problems, such as contact failure.
Refer to the type of protection classifications shown in the following
table and select a Relay suitable to the atmosphere in which it is to be
used.
Classification by Type of Protection
➋-➀-2 Combining Relays and Sockets
Use OMRON Relays in combination with specified OMRON Sockets.
If the Relays are used with sockets from other manufacturers, it may
cause problems, such as abnormal heating at the mating point due to
differences in power capacity and mating properties.
➋-➀-3 Using Relays in Atmospheres Subject to Dust
If a Relay is used in an atmosphere subject to dust, dust will enter the
Relay, become lodged between contacts, and cause the circuit to fail
to close. Moreover, if conductive material such as wire clippings enter
the Relay, it will cause contact failure and short-circuiting.
Implement measures to protect against dust as required by the
application.

➁ Drive Circuits
➋-➁-1 Providing Power Continuously for Long Periods
If power is continuously provided to the coil for a long period,
deterioration of coil insulation will be accelerated due to heating of the
coil. Also see 3-2-7 Using with Infrequent Switching.
➋-➁-2 Operation Checks for Inspection and Maintenance
If a socket with an operation indicator is used, Relay status during
operation can be shown by means of the indicator, thereby facilitating
inspection and maintenance.
Note: The built-in indicator shows that power is being provided to the
➂ Loads
➋-➂-1 Contact Ratings
Contact ratings are generally shown for resistance loads and
inductive loads.
➋-➂-2 Using Relays with a Microload
Check the failure rate in the performance tables for individual
products.
