Ultra High-Density Micro Rectangular HUADA CDb-21Z1 Connector for Precision Applications

The HUADA CDb-21Z1 micro rectangular connector is a compact marvel designed for precision applications. With a pitch of 1.27mm, it offers an ultra-high-density solution for connecting critical components. Whether in aerospace, robotics, or industrial automation, this connector excels where space constraints are paramount. Its versatile core options (ranging from 9 to 51 cores) allow customization to specific needs. The crimping cross-sectional area ensures reliable connections, while compliance with GJB2446 standards and detailed specifications (Q/MB20604-2018 and Q/MB330A-2011) guarantees performance even in demanding environments.
The HUADA CDb-21Z1 connector thrives in extreme conditions. Operating temperature ranges from -55°C to +125°C, making it suitable for both frigid and scorching environments. Its 3A current capacity ensures robust power transmission. With insulation resistance of 5000 mΩ and low contact resistance (8 mΩ), signal integrity remains uncompromised. Vibration and impact resistance (10~2000Hz, 196m/S² and 490 m/s², respectively) ensure longevity. Whether in avionics, automotive, or telecommunications, the CDb-21Z1 delivers reliability, precision, and peace of mind.

Key Features of the HUADA CDb-21Z1 Connector

Physical Specifications: The HUADA CDb-21Z1 comes in two variants:
CDB-8U: This version measures 2.75 x 8.72 x 11.07 inches (6.98 x 22.15 x 28.12 cm) and weighs 9.65 lbs (4.38 kg).
CDB-8P: Similarly sized, the CDB-8P also weighs 9.65 lbs (4.38 kg).
These compact dimensions make them ideal for applications where space is at a premium.
Environmental Resilience: Operating Temperature: For altitudes up to 5000 ft (1524 m), the CDb-21Z1 handles temperatures from 23 to 122°F (–5 to 50°C).
At higher altitudes (up to 10,000 ft or 3048 m), the operating temperature range narrows to 23 to 113°F (–5 to 45°C).
Storage Temperature: Safely store the connector between –13 and 158°F (–25 to 70°C) at altitudes up to 15,000 ft (4572 m).
Relative Humidity: The connector operates flawlessly in environments with 5% to 90% humidity (noncondensing) and stores well at 5% to 95% humidity.
Note: Extreme temperatures above 40°C may impact the connector’s service life.
Power Efficiency: AC Input Voltage: The CDb-21Z1 accepts a wide range of input voltages, from 100 to 277 VAC (+/- 10%).
