Specifications will vary with foreign standards certification ratings. Measurement at same location as "Initial breakdown voltage" section Min. 500MΩ at 100 V DC between coils of 2 coil latching type Detection current: 10mA, Except for between coils of 2 coil latching type Excluding contact bounce time Half-wave pulse of sine wave: 6ms; detection time: 10µs Half-wave pulse of sine wave: 6ms Detection time: 10µs Although NR relays are rated at 10 G/55 cps. vibration resistance, they will withstand up to 60 G/2,000 cps., provided they receive additional support such as anchoring to the PC board with epoxy resin. Refer to 6. Conditions for operation, transport and storage mentioned in AMBIENT ENVIRONMENT 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. See Reference Data for determination of coil voltage versus temperature.
