Measurement: Shock was applied 2
times each in 6 directions along 3
axes with the Relay energized and not
energized to check the shock values
that cause the Relay to malfunction.

For AC
Note: R is a resistor for ampere-
turn correction. This resistor
is built-in to 50-VAC and
higher models.
(The coil has no polarity.)
Note: Pay close attention to the set
coil and reset coil polarities. If
the connections are not
correct, unintended operation
may occur.

Safety Precautions
• For applications that use a 200 VAC power
supply, connect external resistors Rs and Rr to
a 100 VAC Relay.
• Do not apply a voltage to the set and reset coils at the
same time. If you apply the rated voltage to both coils
simultaneously, the Relay will be set.
• The minimum pulse width in the performance column is
the value for the following measurement conditions: an
ambient temperature of 23° C with the rated operating
voltage applied to the coil. The performance values
given here may not be satisfied due to use over time
and a reduction in latching performance due to
changes in the ambient temperature or in the
conditions of the application circuit.
For actual use, apply the rated operating voltage with a
pulse width based on the actual load and reset the
Relay at least once per year to prevent degradation
over time.
• If the Relay is used in an environment with strong
magnetic fields, the surrounding magnetic field can
demagnetize the magnetic body and cause unintended
operation. Therefore, do not use these Relays in
environments with strong magnetic fields.
Relay Replacement
To replace the Relay, turn OFF the power supply
to the load and Relay coil sides to prevent
unintended operation and possible electrical
shock.
Applicable Sockets
Use only combinations of OMRON Relays and
Sockets.
