What is Switching frequency, Ambient temperature, Coil tempe

2.7 Switching frequency: refers to the number of cycles of relay action and release per unit time.

2.8 Ambient Temperature: The normal operating ambient temperature of the relay is generally expressed in the temperature range.

2.9 Coil temperature rise: generally refers to the coil applied at the highest applicable ambient temperature, the specified voltage on the coil, the rated load on the contact point, after the temperature is stabilized, the temperature rise of the coil is generally given the maximum value, expressed as "K". See the test method for details.

2.10 Impact: It is divided into impact stability and impact strength.

    Shock stability: refers to the time when the closed contact is disconnected and the time when the disconnected contact is closed within a specified time. 

The impact value that the relay can withstand is generally expressed by the combination of acceleration value "g" (1g = 9.8m/s2) and duration "ms".

    Impact strength: refers to the impact value that the relay can withstand when the structure of the relay is damaged. It is generally expressed by the  combination of acceleration value "g" and duration "ms". See the test method for details.
