(Notes)
1. When inrush current occurs in the capacitor load circuit or incandescent lamp load circuit, reduce it to less than 5 A. Electrical life of "AuCo" contact
types is 10,000 operations in a 5 A inrush current circuit.
2. When 5 A to 10 A inrush current occurs in the capacitor load circuit or incandescent lamp load circuit, the use of power types is recommended.
2 coil latching types
A) The circuit at right is recommended
when using one coil for latching and the
other coil for reset.
Rectifiers should be inserted in this circuit
when the nominal coil voltage of the NR
relay is more than 24 V DC.
than the measured pick-up voltage. Volt-
age difference on the coils will reduce
contact pressure proportionately.
Continuous bias voltage after an operat-
ing pulse lowers contact pressure and vi-
bration resistance.
NR relays are sensitive enough to be op-
erated by the discharge of energy accu-
mulated in the inner-coil capacitance.The
use of a diode of over 200 V breakdown
will prevent misoperation from this source.
In order to maintain the insulation be-
tween the two coils, connection of the ter-
minal No. 3 and No. 6 or the terminal No.
2 and No. 5 is recommended, as shown in
the right figure.
B) No damage will occur to the coil of ei-
ther the one or two coil latching types
even if the operating voltage is as much
as 2 or 3 times the nominal coil voltage.
C) If separate pulses are applied to each
coil of the 2 coil latching types, the first
pulse will operate when the pulses are of
equal voltage. When voltages differ the
higher voltage will cause operation pro-
vided the voltage difference is greater

Ripple factor
Coils should be operated on pure DC.
Rectified AC may cause changes in the
pick-up/drop-out characteristics because
of the ripple factor. Use of a capacitor in
the circuit is recommended to keep the
ripple factor below 5%.

When designing NR relay circuits
Care should be taken when designing re-
lay circuits since the response of the relay
is so fast that bouncing or chattering from
conventional relays in the circuit may
cause false operation.
When using long lead wires
When long wires (as long as 100 m or
more) are to be used, the use of resis-
tance (10 to 50 Ω) in series with the con-
tact is required in order to eliminate the
effect of the possible inrush current due to
the stray capacitance existing between
the two wires or between the wire and
ground.

AC operation of latching relays
When using circuits such as those at the

Capacitor discharge operation of latching types
When operating latching types by dis-
charge of a capacitor, more reliable oper-
ation can be expected if the time to reach
pick-up voltage is greater than 2 ms at 5
to 10 µF: (24 V type).

Misoperation may occur in self-operated

Residual voltage
When single side stable types or latching
types are driven by transistor or UJT, re-
sidual voltage is sometimes applied to the
coils and decreases contact pressure at
N.O. side even if the transistor or UJT are
in OFF condition. As a result, characteris-
tics of relays may be harmed.Design your
circuits in principle to make such residual
voltage zero.
Short circuit prevention between N.C. and N.O.
The separation of loads or insertion of a
resistor for circuit protection are recom-
mended for the circuits where large cur-
rent flows due to arcing. (See Fig. 1).
