Environmental Performance Parameters Operating temperature -40℃~85℃ The operating temperature range represents the temperature range within which the relay can continuously operate within the operating voltage range of the coil (no water droplet condensation at low temperatures)
Humidity 45%-85%RH it complies with IEC 68-2-3 Test Ca.
Storage temperature -40℃~85℃ The storage temperature range represents the temperature range within which the relay can be stored without damage (no water droplet condensation at low temperatures).
Mechanical vibration Vibration durability capacity 10~55HZ, amplitude 1.0mm In the non - energized state, the relay is vibrated for 2 hours in each direction of the three axes with an amplitude width of 1.5mm and a frequency of 10 - 55Hz. After the test, there should be no abnormality in the appearance and structure, and the electrical performance should comply with IEC 68-2-6 Test Fc.
Vibration resistance (maloperation) 10~55HZ, amplitude 1.5mm In the pulled - in/released state, the relay is vibrated for 5 minutes in each direction of the three axes with an amplitude of 1.5mm and a frequency of 10 - 55Hz. The contact misoperation should not exceed 1ms. After the test, the appearance and structure should not be abnormal, and the electrical performance should comply with IEC 68-2-6 Test Fc.

The contact misoperation does not exceed 1 millisecond, which complies with IEC 68 - 2 - 27 Test Ea.
Cold resistance Cold resistance in use When there is no input state, the relay should be continuously maintained at a temperature of -30 ± 2℃ in the constant temperature box for 2 hours. When conducting the rated voltage test on the operating circuit in the original state, the relay should operate normally. (There is no water droplet condensation phenomenon at low temperature.)
Cold resistance in storage The relay should be continuously maintained at a temperature of -40 ± 2℃ in the constant temperature box for 72 hours. Then, after removing water droplets at room temperature for 1 - 2 hours, conduct structure, action, insulation impedance, and withstand voltage tests. The results should meet the requirements. (There is no water droplet condensation phenomenon at low temperature.)
Heat resistance Heat resistance in use With the rated voltage provided on the operating circuit and the rated current provided at the contact part, the relay should be continuously maintained at a temperature of 85 ± 2℃ for 2 hours. Conduct the relay action test in the original state, and the results must meet the specification requirements.
