3. Dimension: Inner hole diameter, height and width.
4. Working Environment: temperature, humidity, indoor or outdoor, protection grade.
5. Connector Type: pin type, flying leads type, standard interface, etc.
6. Application: some special application areas require the use of specially designed solenoid coils, such as industries that require waterproof, must use IP67 or higher grade solenoid valve coils.
