1. First understand the necessary conditions
① The power supply voltage of the control circuit, the maximum current that can be provided;
②The voltage and current in the controlled circuit;
③ How many groups and what form of contacts are required for the controlled circuit. When selecting relay HKE, the power supply voltage of the general control circuit can be used as the basis for selection. The control circuit should provide enough working current to the relay HKE, otherwise the pull-in of the relay HKE will be unstable.
2. After checking the relevant information to determine the conditions of use, you can search for the relevant information to find out the model and specification number of the relay HKE you need. If you already have relay HKE, you can check whether it can be used according to the information. Finally, consider whether the size is appropriate.
3. Pay attention to the volume of the appliance. If it is used for general electrical appliances, in addition to considering the chassis volume, the small relay HKE mainly considers the circuit board installation layout. For small electrical appliances, such as toys and remote control devices, ultra-small relay HKE products should be used.
