SE8502 Series

SE8502 is an Industrial 2-port IP68 Serial Server, offering waterproof, dustproof, and vibration-resistant.

There is a strong demand for reliable and rugged networking solutions, that can be used for the industrial workplace in harsh environmental conditions, such as high levels of moisture, dust, heat, electrical interference, and vibration. SE8502 is a device that has IP68-rated housing and M12 metal connectors. It also provides a wide operating temperature range from -40°C ~

SE8502 supports multiple link mode with TCP server/client, UDP and VirtualCOM, that can be configured by Windows-basedutility. In addition, M12 connectors secure a firmly connecting, and prevent loose from vibrating condition, such as in moving vehicles.
