The contact is the most important structural part of the relay. The service life of the contact is affected by the contact material, the voltage and current value on the contact (especially the voltage and current waveform when it is on and off), the type of load, and the switching Due to the influence of frequency, environmental conditions, contact

Applying rated voltage to the coil is the basis for the normal operation of the relay. When only applying a voltage exceeding the operating voltage, the relay can be tooled, but considering the changes caused by power supply voltage fluctuations and temperature rise, which will affect the normal tooling of the relay, the rated voltage must be applie

3.1 Precautions for plastic-encapsulated relays Plastic-encapsulated relays have good environmental resistance, but please pay attention to the following matters when using them to avoid malfunctions. 3.1.1 About the use environment Plastic-encapsulated relays are not suitable for environments with special air tightness requirements. Please avoid us

4.1 About ambient temperature and environment Please note that the ambient temperature of the place of use should not exceed the value specified in the product manual. In addition, if there is a lot of dust in the surrounding environment, or there is water vapor, sulfide gas (SO2, H2S, etc.) or organic gas, sulfide film, oxide film or dust will be f

5.1 About bottom view and top view Generally, the bottom view is obtained by projecting from the end face of the PCB of the relay, and the top view is obtained by projecting from the opposite direction (that is, the top surface of the relay housing). Please pay attention when using the product manual and installing the relay. 5.2 Installation direct
