JACOB connector domestic substitution customer feedback record

JACOB GmbH was founded in 1922 and is a well-known German manufacturer of cable glands and cable entry systems. The headquarters is located near Stuttgart in Kernen. The company's product line covers plastics, brass, and stainless steel materials, capable of meeting multiple requirements such as IP68/IP69K protection level, resistance to extreme temperatures (from -60°C to +200°C), EMC electromagnetic shielding, and explosion-proof certification (jacob-gmbh.de). Its products are widely used in industries such as new energy, industrial equipment, wind power, rail transit, automotive electronics, and charging stations. Thanks to strict laboratory testing and highly integrated production processes, it has become a globally recognized high-reliability connector brand.

Customer Feedback Summary: Practical Application Experience of Domestic Connectors
During our cooperation with multiple clients, we have collected real feedback on the application of domestic substitute products, which is mainly focused on the following points:
Performance of stability
Most customers feedback that domestic connectors can maintain good sealing and protective effects in daily use, especially with strong stability in complex working conditions such as humidity and dust.
Ease of installation
Compared with imported products, domestically produced connectors have continuously optimized their structural design, simplified installation steps, improved assembly efficiency, and received recognition from production and manufacturing enterprises.
Cost-performance advantage
At the same performance level, domestic substitute products are more competitive in price, especially when purchased in bulk, significantly reducing costs for customers.
4. Insufficient and Challenges
Some customers have also put forward suggestions for improvement:
●Individual models have slightly lower stability of sealing materials under extreme high temperatures than the JACOB high-end series.
●The EMC shielding efficiency still has room for improvement in some high-frequency application scenarios.

The certification scope of explosion-proof models still needs to be expanded to meet the broader industry demand.

Improvement Measures: From Feedback to Optimization
We have formulated the following improvement measures in response to customer feedback:
Material upgrade: Introduce new sealing materials with high-temperature resistance and aging resistance, gradually narrowing the gap in extreme environmental adaptability with the JACOB WADI series.
Inheriting the design philosophy of the JACOB PERFECT series, further optimize the thread and sealing part structure, enhancing the installation feel and reliability.
EMC performance enhancement: Collaborate with material suppliers to develop shielding structures with higher conductivity, enhancing stability in high-frequency environments.

4. Certification Expansion: Accelerate domestic and international explosion-proof certification applications, expand the application scenarios of products, and meet the compliance requirements of more industries.

Customer feedback is an important driving force for the continuous progress of domestic connectors. By benchmarking the high standards of JACOB GmbH, we have made substantial progress in stability, cost performance, and application scenarios, while also continuously improving the shortcomings. In the future, we will continue to listen to customer voices and promote the influence and competitiveness of domestic connectors in the global market.
