A Using Relays
• When actually using Relays, unanticipated failures may occur. It is
therefore essential to test the operation is as wide of range as
possible.
• Unless otherwise specified in this catalog for a particular rating or
performance value, all values are based on JIS C5442 standard
test conditions (temperature: 15 to 35°C, relative humidity: 25% to
75%, air pressure: 86 to 106 kPa). When checking operation in the
actual application, do not merely test the Relay under the load
conditions, but test it under the same conditions as in the actual
operating environment and using the actual operating conditions.
• The reference data provided in this catalog represent actual
measured values taken from samples of the production line and
shown in diagrams. They are reference values only.
• Ratings and performance values given in this catalog are for
individual tests and do not indicate ratings or performance values
under composite conditions.
