QA20012: 2.0mm Pitch Battery Management System Connector
Product Features
QA20012 Series (IRISO-13065 Connector)
The QA20012 series is a popular 2.0 mm pitch double-row reflow soldering connector widely used in Battery Management Systems (BMS), fully compatible with the original manufacturer's male and female connectors.


Board-Side Connector
Horizontal SMT double-row configuration. Metal components on both sides provide structural strength without the need for screws.
Wire-Side Housing
Features an innovative bridge-type design that resists deformation and prevents accidental unlocking from foreign objects. The pre-assembled TPA (Terminal Positioning Assurance) simplifies installation, reduces labor and cost, strengthens terminal fixation, extends product life, and optimizes electrical performance.


Terminals
Quadrilateral structure with double-sided contact between male and female connectors. Internal locking between board and wire ends ensures vibration resistance, high retention force, and stable electrical contact, meeting stringent automotive application requirements.

Applicable Standards
USCAR 2.0, QC/T1067-2017, and other automotive standards.
Application Scenarios
Designed for critical applications in automotive BMS, ECUs, and other EV battery management systems, the QA20012 ensures reliable connection performance in harsh automotive environments.

Production Process
Using a dual-branch parallel production process, copper strips are stamped and plated to enhance performance, while core components are manufactured through injection molding. The entire workflow - from assembly and testing to packaging-is strictly controlled to ensure reliable product delivery.

Packaging and Transportation
JKUN connectors are packaged in standardized materials and secured on pallets. They must be stored in their original packaging within a clean, temperature- and humidity-controlled environment. Transportation methods are flexible, but care must be taken to prevent impact damage, with emphasis on safe loading, unloading, and packaging recycling.

Certification + Independent Patents: Dual Technological Guarantee
JKUN strengthens its product foundation through comprehensive authoritative certifications and proprietary patents. With certifications including IATF 16949 and ISO standards, the company ensures compliance across all scenarios. Holding multiple utility model patents, JKUN focuses on core technologies such as structural design and manufacturing processes, establishing a solid foundation for product stability, reliability, and suitability for automotive applications.
