When selecting a 5 pin electric bike connector, several factors must be considered to ensure compatibility and performance. First and foremost, the material composition of the connector is paramount. Connectors made with high-grade materials such as TPU and PA inserts, combined with brass contacts and gold plating, are known for their durability and reliability. These materials offer excellent anti-corrosion properties and ensure a stable connection, which is vital for the smooth operation of e-bikes. Additionally, the temperature range within which the connector can operate is crucial. A good connector should function efficiently between -20℃ to +80℃, accommodating various environmental conditions. Furthermore, the insulation resistance and contact resistance are critical specifications that determine the connector's ability to perform under different electrical loads, ensuring safety and efficiency in e-bike operations.
