*8 Although NR relays are rated at 10 G/55 cps. vibration resistance, they will with-
stand up to 60 G/2,000 cps., provided they receive additional support such as
anchoring to the PC board with epoxy resin.
*9 Refer to 5. Conditions for operation, transport and storage mentioned in
AMBIENT ENVIRONMENT (Page 61)
*10 Total temperature (ambient temperature plus temperature rise in coil) should not
exceed 90°C 194°F for single side stable, and 105°C 221°F for latching relays.

APPLICATION HINTS
Contact protection circuit
When using NR relays in inductive load circuits, a contact protection circuit is recommended.
Examples:
CR CR
Diode
S Relay contact
rc
L
L : Inductive load
S
r
c
L
S
L
1. r = more than 20 to 30 ohms
2. In an AC circuit impedance of L is to be
somewhat smaller than impedance of r
and c.
Can be used for both AC and DC circuits.
Use 500 to 1000 ohms for r and 0.1 µF to
0.2 µF 200 V for c in a general 12 to 24 V
load circuit.
For DC circuits only.
