Does Water Ingress To The Sd Card Holder Push-type Terminal Block Connector Have A Big Impact On Drone Aerial Photography? How Is The Waterproof Performance?

Water ingress into the SD card holder push wire terminal block will indeed have a significant impact on drone aerial photography. Most consumer drones' SD card holders push in terminal block wire connector are not specially waterproofed. Once water enters the push in wire terminal block, it may cause short circuits, abnormal data reading and writing, or even permanent damage. Water stains will corrode metal contacts, causing poor contact, resulting in the inability to save or read aerial photography materials normally. push fit terminal block connector Severe water ingress may also cause a short circuit in the circuit board, affecting the power supply system of the entire machine.

Currently, mainstream consumer drones on the market, such as the DJI series, usually have a waterproof rating between IPX1 and IPX3, which can only prevent light rain or slight water mist. Professional drones such as the Matrice 300 RTK can reach an IP45 protection level, but the SD card slot is still a relatively fragile part. Some industrial drones use a fully sealed design, but this will sacrifice some heat dissipation performance.

When water is found in the SD card holder push connector block, the power should be turned off immediately and the battery should be removed. The contacts should be cleaned with anhydrous alcohol and used after they are completely dry. For long-term operation in a humid environment, it is recommended to use an SD card with a waterproof rubber ring or special accessories for waterproof drones. Professional film and television teams are usually equipped with waterproof storage boxes to replace dry memory cards in time after shooting in rainy days.

Preventive measures include: avoid flying in the rain, do not hover at low altitude over the water, and check whether the card slot seal is intact before takeoff. Some modification plans can be equipped with silicone dust plugs, but this may affect heat dissipation. It is recommended to use a dual-card backup solution for aerial photography operations, and important materials are transmitted to mobile devices in real time to minimize the risk of data loss.
