Note ：(1) Initial value. Operate and release time excluding contact bounce.
(2) Special version of high temperature 85°C can be selected.
(3) Unless otherwise specified, all tests are under room temperature and humidity.
(4) Consider the heat of PCB is necessary, please check the actual condition of PCB.
(5) Applying no diode to this relay. The life expectancy will be lower when a diode is used. To use
a varistor (ZNR) could absorb the coil surge of relay that is recommended.
(6) Do not use the relay exceeding the coil rating, contact rating and life expectancy, or this may cause
the risk of overheating.
(7) To assure optimum performance, avoid the relay from dropping, hitting, or other unnecessary shocks.
(8) Flux tight version is recommended. If there is cleaning process and sealed type is selected,
the vent-hole should be removed after the process.
(9) Usage, transport and storage conditions
● 1. Temperature: -40～+70°C
● 2. Humidity: 5 to 85% R.H.
● 3. Pressure: 86 to 106 kPa
● Furthermore, the humidity range varies with the temperature. So, use relays
within the range indicated in the graph below.
