An introduction to the backshell of the D38999 III series, including M85049/38, M85049/39, M85049/38, M85049/20, M85049/69, M85049/88, M85049/90, M85049/18 series
Introduction to D38999 III Series Backshells
The D38999 III series backshells are core accessories compatible with Amphenol standards, specifically designed for D38999 series circular connectors. They are precisely matched with specific models of the M85049 series, providing reliable cable fixation, protection and signal guarantee for electronic connectors, and are widely used in harsh environments such as aerospace and military equipment.
The key backshell models introduced this time include M85049/38, M85049/39, M85049/20, M85049/69, M85049/88, M85049/90, and M85049/18. All strictly comply with Amphenol standards and MIL-DTL-38999 specifications, and are perfectly compatible with D38999 III series circular connectors to ensure convenient installation and stable connection.
These backshells are made of high-quality aluminum alloy base material, and some models are equipped with anti-corrosion plating, which have excellent anti-vibration and anti-impact performance. The operating temperature ranges from -65℃ to 200℃, which can adapt to extremely harsh environments.
Among them, M85049/20 (suitable for cable diameter 4-12mm, length 38mm), as a wall-mounted adapter backshell, focuses on cable organization and protection;
M85049/69 (suitable for cable diameter 6-15mm, length 42mm) focuses on cable strain relief, limiting cable bending damage and meeting specific cable diameter requirements.The two backshells M85049/38 and M85049/39 focus on sealing protection, which can effectively block the intrusion of dust and water vapor and ensure the stability of electronic connector signal transmission;
M85049/18 (suitable for cable diameter 2-8mm, length 32mm).
M85049/88 (suitable for cable diameter 7-16mm, length 45mm).
M85049/90 (suitable for cable diameter 8-18mm, length 48mm) are optimized for different installation scenarios, balancing light weight and durability to meet diverse assembly needs.
As key supporting components of D38999 III series circular connectors, these backshells not only enhance the mechanical performance and environmental adaptability of electronic connectors, but also improve the EMI shielding effect of the entire connection system to ensure signal integrity. Their standardized design complies with Amphenol standards, with strong interchangeability and efficient installation, providing strong support for high-reliability connections in aerospace, military, industrial and other fields.
