The life expectancy of the relay can be determined from the electrical
service life curve shown below, based on the rated switching current
(I
obtained maximum switching current of 2 A is slightly over 300,000
operations (see circled point on graph below).
However, with a DC load, it may become difficult to break the circuit
of 48 V or more due to arcing. Determine the suitability of the relay in
actual usage testing.
The correlation between the contact ratings is shown in the following
figure:
Minimum Permissible Load
The minimum permissible load indicates the lower limit of switching
capability of a relay as the reference value. Such minute load levels
are found in microelectronic circuits. This value may vary, depending
on operating frequency, operating conditions, expected reliability
level of the relay, etc. It is always recommended to double-check
relay suitability under actual load conditions.
In Omron catalogs, the minimum permissible load of each relay is
indicated as a reference value. It indicates failure level at a reliability
level of 60% (λ
presumed to occur per 10,000,000 (ten million) operations at a reli-
ability level of 60%.

Electromechanical Relays
■ Terms Related to Coils
Rated Coil Voltage
A reference voltage applied to the coil when the relay is used under
normal operating conditions.
Coil Symbols
Coil Resistance (Applicable to
DC-switching Relays only)
The resistance of the coil is measured at a temperature of 23°C with
a tolerance of ±10% unless otherwise specified. (The coil resistance
of an AC-switching type relay may be given for reference when the
coil inductance is specified.)
Cold Start
The ratings set forth in the catalog or data sheet are measured at a
coil temperature of 23°C unless otherwise specified.
Maximum Voltage
The maximum value of permissible over voltage or pulsating voltage
fluctuations in the operating power supply to the relay coil.
Minimum Pulse Width
The minimum value of the pulse voltage required to set and reset a
latching relay at a temperature of 23°C.
Must Operate (Must Set) Voltage
The threshold value of a voltage at which a relay operates when the
input voltage applied to the relay coil in the reset state is increased
gradually.
Must Release (Must Reset) Voltage
The threshold value of a voltage at which a relay releases when the
rated input voltage applied to the relay coil in the operating state is
decreased gradually.
Power Consumption
The power (= rated voltage x rated current) consumed by the coil
when the rated voltage is applied to it. A frequency of 60 Hz is
assumed if the relay is intended for AC operation. The current flows
through the coil when the rated voltage is applied to the coil at a tem-
perature of 23°C. The tolerance is +15%/-20% unless otherwise
specified.
