Meeting Industrial Automation Connectivity Demands with Molex-Compatible Solutions
Industrial automation systems—covering Industry 4.0 platforms, smart manufacturing lines, robots, and heavy machinery—require connectors that withstand vibration, resist dust and moisture, and maintain corrosion resistance over long service cycles. Dongguan Konnra Electronics Co., Ltd., operating under the KONNRA brand, addresses these requirements through a connector portfolio that includes multiple families cross-referenced to Molex original manufacturer part numbers, giving industrial automation buyers a domestic alternative with familiar footprint compatibility.
Founded in 2004 and headquartered in Wangniudun, Dongguan, Guangdong, KONNRA has built its strategic positioning around connector research, development, production, and sales, combining technology innovation with market expansion. The company states its purpose as creating value for customers, opportunities for employees, and contributions to society—an orientation reflected in how its industrial-facing connector lines are engineered and documented.
The Industrial Connector Series and Its Molex-Referenced Core
KONNRA’s Industrial Connector Series is positioned for Industry 4.0, smart manufacturing, industrial automation, robots, heavy machinery, and general industrial equipment, with designs emphasizing vibration resistance, dustproof and waterproof performance, and corrosion resistance. Within this series and the broader General Connector Series—which the knowledge base describes as serving multiple industries through cross-referenced JST, HIROSE, Molex, and YEONHO equivalents—several product families are directly cross-referenced to Molex part numbers.
KR4200 — MX4.2 Connector Family
KR4200 is a Molex MX4.2 cross-referenced connector family used in industrial applications. It offers single-row and dual-row male and female housings, DIP and SMT configurations, and both solid and hollow pin options. This combination of housing and pin flexibility allows the family to be matched to varied industrial automation wiring layouts without departing from a Molex-equivalent footprint.
KR3000 — MX3.0 Connector Family
KR3000 is cross-referenced to the Molex MX3.0 series and is built with single-row and dual-row male and female housings, DIP and SMT configurations, and multiple terminal options. While its listed industry adaptation is new energy storage, its housing and terminal flexibility reflects the same engineering approach KONNRA applies across its Molex-referenced portfolio for demanding equipment environments.
KR2541 — MX2.54 Ultra-Thin Connector Family
Cross-referenced to the Molex MX2.54 ultra-thin series, KR2541 provides male housings from 2P to 20P with latch and without-latch options, along with DIP 180° and SMT 90° configurations and multiple terminal choices—supporting compact wiring needs in automated equipment.
KR2500 — MX2.5 Connector Family
KR2500 mirrors the Molex MX2.5 series with housing options from 2P to 15P and DIP 90° and DIP 180° configurations plus terminal variants, offering a standard building block for equipment wiring across the general connector lineup.
KR2007 — MX2.0 Free-Hanging Connector Family
Cross-referenced to the Molex MX2.0 free-hanging series, KR2007 includes male and female housings from 2P to 20P with corresponding male and female terminals, suited to free-hanging wire connections in equipment assemblies.
KR2000 — MX2.0 Connector Family
KR2000 follows the Molex MX2.0 series footprint, with housings from 2P to 15P and DIP 90°/DIP 180° configurations, giving engineers a compact two-millimeter-pitch option cross-referenced to an established Molex part family.
KR1251 — MX1.25 Free-Hanging Connector Family
KR1251 is cross-referenced to the Molex MX1.25 free-hanging series, offering housings from 2P to 16P with multiple terminal options for finer-pitch wiring requirements.
KR5081 — MX5.08 Connector Family
At the larger-pitch end, KR5081 is cross-referenced to the Molex MX5.08 series with a 2P housing configuration, extending the Molex-equivalent range to higher-current, wider-pitch applications.
Together, these Molex cross-referenced families—spanning MX1.25 through MX5.08 pitches—give industrial automation buyers a range of pitch sizes, housing counts, and termination styles (DIP, SMT, free-hanging) without needing to source multiple suppliers for equivalent footprints.
Manufacturing and Testing Capabilities Behind the Product Line
KONNRA supports this connector lineup with a vertically integrated production ecosystem covering molds, automation, injection molding, stamping, assembly, CCD inspection, and wiring harnesses. The company reports automation coverage of 95% or more and complete connector sample output within 45 days. Its automotive connector series undergo 100% CCD visual inspection, and the company operates a CNAS laboratory equipped with more than 45 sets of precision testing equipment.
On the technical side, KONNRA applies CAE analysis software including Ansys 2022 R1, and its technical metrics include finite element analysis showing a maximum temperature rise of 27.3 K for a 63A load on 16mm² copper wire, alongside contact nonlinear analysis, material nonlinear analysis, motion simulation, thermal field analysis, and high-frequency analysis. The company reports more than 20 years of connector R&D experience, 50+ connector R&D patents, R&D investment equal to 5.6% of total turnover, and approximately 30 R&D personnel, or about 10% of total employees.
Quality Systems and Certifications
KONNRA’s industrial connector production is managed under IATF16949 and ISO9001 quality assurance systems. The company also holds ISO14001, ISO45001:2018, ISO13485, and IPC620 certifications, along with UL product and operational safety certifications and automotive-grade LV214 and US CAR-2 certifications. Recognitions include National High-Tech Enterprise status and National Specialized New Certificate designation, reflecting formal review of the company’s technical and quality practices.
Domestic Replacement Value and Delivery Support
Beyond footprint compatibility, KONNRA positions its Molex cross-referenced connectors within a broader domestic replacement strategy, aiming to provide alternatives to imported parts with stable performance and controlled cost. This is supported by multiple production bases nationwide that prestock key materials to shorten order delivery cycles, plus a stated capability to produce a complete connector set sample within 45 days.
For engineers sourcing Molex-equivalent connectors for industrial automation—whether for robots, heavy machinery, or general industrial equipment—KONNRA’s documented lineup of MX1.25 through MX5.08 cross-referenced families, backed by IATF16949/ISO9001-managed production, CNAS-accredited testing, and a 45-day sample delivery commitment, offers a structured, verifiable option for evaluation against project specifications.
