1. Do not exceed the rated voltage of load current during the use of OMRON relay, because when the applied rated voltage is too large, it may cause a local short circuit between the cores of the OMRON relay coil and poor operation of the AC operation relay. In addition, there is a possibility that the polarity of the relay is wrong with a surge absorbing diode.
2. The phenomenon of poor insulation between the outputs of OMRON relay is mainly due to the arc discharge between the relay contacts being distorted by the external magnetic field or the magnetic field generated by the operating coil, reaching the coil terminal and generating flashover. However, in contrast to the accumulation of carbon or powder scattered from the contacts due to arcing that occurs between the contacts when the OMRON relay is loaded, it is the root cause of insulation defects that cause insulation operation or a drop in the withstand voltage value.
3. In the power circuit of OMRON relay, the problem of increased contact resistance sometimes occurs. In this case, the main reason is that the organic matter adhering to the surface of the relay contact is affected, and baking (heating under high vacuum conditions) is carried out to remove the gas discharged from the molded products that make up the relay in advance. We have also developed molded products that significantly reduce gas emissions, and are gradually being used in various products.
Fourth, secondly, the relay has high requirements for small and high-sensitivity equipment, so the core wire of the coil is getting thinner and thinner. Because the relay is mounted on a printed circuit board, it is cleaned but sometimes the ultrasonic energy is concentrated on the coil core and the wire breaks. This is mainly because the general relay cannot be cleaned with water to clean dust and debris, otherwise in the case of using water, it will produce a strong standing wave, which may cause the core wire of the coil to break, so it must be confirmed in advance.
5. The current generated by the increase in the temperature of the coil of the DC operation relay decreases (about 0.4% per 1°C rise) to prevent the polarity of the relays built in the diodes connected in the reverse connection from being misplaced. Otherwise, the relay may vibrate and cause the wire to break, and in severe cases, the relay may be burned directly.
