How to select the shielding gasket for inverter cabinet doors

Selecting the right shielding gasket for inverter cabinet doors requires comprehensive consideration of gap type, shielding effectiveness requirements, environmental conditions, and installation method. Gasket types include: conductive rubber gaskets, offering good environmental sealing and shielding effectiveness, suitable for dust and water-proof applications; wire mesh gaskets, offering good elasticity and low cost, but with generally poor environmental sealing; beryllium copper finger springs, offering good elasticity, low contact impedance, and long lifespan, suitable for doors with frequent opening and closing, but lacking environmental sealing; and conductive cloth gaskets, which are soft and easy to install, but have slightly lower durability.

Selection steps: Determine the required shielding effectiveness level and frequency range. Measure the gap dimensions (gap, unevenness) between the cabinet door and the cabinet frame. Select the appropriate gasket cross-sectional shape and size based on the gap dimensions and compression requirements. Consider environmental factors such as temperature, humidity, and corrosiveness, and select weather-resistant materials. Determine the installation method: adhesive, clips, or other mechanical fixing. Evaluate the gasket's compression set characteristics and service life. Samples from the supplier are usually required for testing and verification. Eintech offers a variety of shielding gaskets and selection guides to help customers choose the most suitable shielding solution for their inverter cabinet doors.
