*6 Half-wave pulse of sine wave: 6ms
*7 Detection time: 10µs
*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.

DIFFERENCES BETWEEN NR RELAYS AND REED RELAYS
Structure
NR relays
Reed relays
"Getter" holes are formed on both pole
shoes to obtain uniform contact resis-
tance throughout life. Film-forming phe-
nomena on contacts is thus fully
prevented.
