The wave form should be rectangular. If it includes ripple, the ripple factor should be less than %. However, check it with the actual circuit since the characteristics may be slightly different. The nominal voltage should be applied to the coil for more than ms to set/reset the latching type relay.. connection When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction. 3. External magnetic field Since RK relays are highly sensitive polarized relays, their characteristics will be affected by a strong external magnetic field. Avoid using the relay under that condition.. Soldering and cleaning ) Perform manual soldering under the conditions below. Within s at C F Within 3 s at 3 C F Preheat according to the following conditions. Temperature C F or less Time Within minute Soldering should be done at ± C ± F within s. ds_3 en_rk: J Inter-relay distance, (mm, inch) ) For automatic cleaning, the boiling method is recommended. Avoid ultrasonic cleaning which subjects the relays to high frequency vibrations, which may cause the contacts to stick. It is recommended that alcoholic solvents be used.. Conditions for operation, transport and storage conditions ) Ambient temperature, humidity, and atmospheric pressure during usage, transport, and storage of the relay: () Temperature: to +7 C to + F () Humidity: to % RH (Avoid freezing and condensation.) The humidity range varies with the temperature. Use within the range indicated in the graph below. (3) Atmospheric pressure: to kpa Temperature and humidity range for usage, transport, and storage: Humidity, %RH Tolerance range (Avoid freezing (Avoid when used at condensation temperatures lower when used at than C 3 F temperatures higher than C 3 F +3 Temperature, C F 7 + ) Condensation Condensation forms when there is a sudden change in temperature under high temperature and high humidity conditions. Condensation will cause deterioration of the relay insulation. 3) Freezing Condensation or other moisture may freeze on the relay when the temperature is lower than C 3 F. This causes problems such as sticking of movable parts or operational time lags. ) Low temperature, low humidity environments The plastic becomes brittle if the relay is exposed to a low temperature, low humidity environment for long periods of time.. Latching relay In order to assure proper regardless of changes in the ambient usage temperature and usage conditions, nominal voltage should be applied to the coil for more than 3 ms to set/reset the latching type relay.
