Compact Micro-D HUADA CDb-21ZY Connector for Harsh Environments

The HUADA CDb-21ZY micro connector combines compact dimensions with robust construction. Its 1.27mm pitch allows for high-density configurations, accommodating 9 to 51 cores. Whether in extreme temperatures (-55°C to +125°C) or harsh environments, this connector excels. It meets GJB2446 standards, ensuring reliability even under pressure (600V) and vibration (10~2000Hz). With low contact resistance (8 mΩ) and insulation resistance (5000 mΩ), it’s a go-to choice for demanding applications.
The CDb-21ZY connector thrives in aerospace, defense, and industrial settings. Its mechanical life spans 500 cycles, making it durable for repeated use. Engineers appreciate its wide temperature range, while the 1.1mm row spacing simplifies installation. Whether you’re designing avionics systems or rugged machinery, the HUADA CDb-21ZY delivers reliable connectivity and peace of mind.

Key Features of the HUADA CDb-21ZY Connector

Physical Specifications: Weight: The CDb-8U variant weighs approximately 9.65 lbs (4.38 kg).
Similarly, the CDb-8P version also weighs around 9.65 lbs (4.38 kg).
Dimensions (Height x Depth x Width): For the CDb-8U: Height: 2.75 inches (6.98 cm)
Depth: 8.72 inches (22.15 cm)
Width: 11.07 inches (28.12 cm)
Likewise, the CDb-8P shares the same dimensions.
Environmental Specifications: Operating Temperature Range: The connector operates reliably between 23°F and 122°F (-5°C to 50°C) up to an altitude of 5000 ft (1524 m).
For more extreme conditions, it still performs well between 23°F and 113°F (-5°C to 45°C) up to 10,000 ft (3048 m).
Storage Temperature: When not in use, it can be stored safely within a temperature range of -13°F to 158°F (-25°C to 70°C) up to 15,000 ft (4572 m).
Relative Humidity: Operating relative humidity spans from 5% to 90% (noncondensing).
Storage relative humidity allows for 5% to 95% (noncondensing).
Altitude Tolerance: The connector functions seamlessly up to 10,000 ft (3048 m) above sea level during operation.
For storage, it can handle altitudes up to 15,000 ft (4572 m).
Note: If operating above 40°C, consider its impact on service life.
Power Requirements: The connector dissipates switch power only (excluding Power over Ethernet, which occurs at the end device).
