High-Density Micro Rectangular HUADA CDb-31Z Connector for Demanding Applications

The HUADA CDb-31Z micro rectangular electrical connector combines compact design with robust performance. Engineered for precision, it boasts a 1.27mm pitch and accommodates up to 31 cores, making it ideal for space-constrained environments. Whether in aerospace, medical devices, or industrial machinery, this connector delivers high current capability (3 A), low contact resistance (8 mΩ), and a wide temperature range (-55°C to +125°C). Its mechanical endurance of 500 cycles ensures reliability, while the 1.1mm row spacing and crimping cross-sectional area (0.05mm²~0.15mm²) optimize efficiency. Compliance with GJB2446 and Q/MB20604-2018, Q/MB330A-2011 specifications ensures top-notch quality.
The HUADA CDb-31Z connector thrives in challenging conditions. Withstanding work pressures of 4.4 KPa, vibrations from 10~2000Hz (196m/S2), and impacts up to 490 m/s2, it’s a reliable choice for critical applications. Its insulation resistance exceeds 5000 mΩ, ensuring signal integrity. Whether you’re designing cutting-edge electronics or intricate machinery, the HUADA CDb-31Z delivers compact power and resilience. Explore its capabilities and elevate your designs!

Key Features of the HUADA CDb-31Z Connector

Boom Design and Pedestal: The unique combination of a “Z” and roll-and-fold boom design in the HUADA CDb-31Z provides both maneuverability and a low unfolding height (18 ft 9 in or 5.73m). This makes it suitable for use under low-roofed buildings.
The boom pedestal, which absorbs all forces, ensures less twist, reduced forces transferred to the truck frame, and quick setup. It features a rack-and-pinion slewing system for easy maintenance and access openings to simplify changing the turret pipe1.
Outriggers: The fully hydraulic outriggers have integral cylinders and are only 20 ft 8 in (6.3m) wide (front and rear). This allows operation on congested job sites.
The front outriggers diagonally telescope, while the rear ones swing out with Putzmeister’s unique “X” brace outrigger design1.
Concrete Pump: The HUADA CDb-31Z offers both high volume and high pressure. With the same setup, it provides 210 yd3/hr output and 1233 psi concrete pressure (on the rod side).
Features include a free-flow hydraulic system, hard-chromed concrete cylinders, and automatic lubrication of the concrete pistons for long service life. The pump has a fully adjustable volume control, allowing slow pumping while retaining full concrete pressure and boom speed12.
Dimensions: Length: Varies based on the specific model (e.g., 31Z.12L, 312.16H).
Width: Refer to the specifications for each model.
Height: Unfolding height is 18 ft 9 in (5.73m).
Wheelbase, front axle weight, and rear axle weight are also model-specific2.
