() Unless otherwise specified, all tests are under room temperature and humidity. (3) Consider the heat of PCB is necessary, please check the actual condition of PCB. (4) Do not use the relay exceeding the coil rating, contact rating and life expectancy, or this may cause the risk of overheating. (5) To assure optimum performance, avoid the relay from dropping, hitting, or other unnecessary shocks. 5
() Do not switch the contacts without any load as the contact resistance may become increased rapidly. (7) Flux tight version is recommended. If there is cleaning process and sealed type is selected, the vent-hole should be removed after the process.
