Life expectancy Mechanical (frequency 9,000 ops./hr) Operating ambient temperature -40~+85C (no freezing) Weight Approx.170 g Notes : (1) Initial value. Operate and release time excluding contact bounce. (2) Unless otherwise specied, all tests are under room temperature and humidity. (3) Consider the heat of PCB is necessary, please check the actual condition of PCB. (4) 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. (5) Do not use the relay exceeding the coil rating, contact rating and life expectancy, or this may cause the risk of overheating. (6) To assure optimum performance, avoid the relay from dropping, hitting, or other unnecessary shocks. (7) Do not switch the contacts without any load as the contact resistance may become increased rapidly. (8) Please contact Song Chuan for the detailed information.
