CLIFF connector domestic substitution performance stability actual test

CLIFF Electronic Components is a well-established connector manufacturer in the UK with over 40 years of design and manufacturing experience. Known for its high reliability and diverse product range, it is widely used in medical equipment, broadcast systems, industrial instruments, building automation and other fields.

Its representative products include:
●DualSLIM USB Feedthrough series: Integrated dual USB (USB 2.0/USB 3.0/USB-C), installable in standard XLR panel cutouts, achieving simultaneous data and power transmission, while saving space and component count.
●Feedthrough series (such as HDMI, Cat.6 RJ45, DisplayPort): Support front/rear panel installation, featuring flexibility and stable connection characteristics.
●Optical TOSLINK interface: Excellent anti-electromagnetic interference capability in digital audio transmission, ensuring high signal-to-noise ratio and stable performance.

CLIFF has full design and manufacturing capabilities, with some products directly produced in the UK, ensuring stable supply chain and consistent product quality.

Performance Test Approach and Data Reference for Domestic Connectors
In order to verify the performance and stability level of domestic connectors, we conducted comparative tests in combination with CLIFF standard products, focusing on the following test items:
Breakdown and short-circuit reliability test
Simulate long-term insertion and extraction use, test the change in contact resistance of domestic substitute connectors after 10,000 insertions and extractions; data shows that the contact resistance of domestic products does not exceed 10%, and the difference from the CLIFF standard does not exceed 15%.
Signal Integrity Test
Taking the Cat.6 RJ45 Feedthrough interface as an example, conduct high-speed data transmission tests (1 Gbps): the error rate (BER) of domestic products is ≤10⁻¹², which is comparable to that of CLIFF products.
Environmental stress test
After 48 hours of testing under the simulated internal heat dissipation environment of a 40℃ instrument that meets the IP protection standard, the temperature rise of the domestic connector is controlled within 10℃, with no loosening of the pins, and it is close to the imported equivalent product.
4. Interference Resistance and Lifespan Testing
TOSLINK optical interface can continuously transmit for 1 hour in a simulated high electromagnetic interference environment with no significant disconnection. The performance of the domestic optical interface is consistent with CLIFF.

Through the above experimental data, domestic connectors have approached or reached the CLIFF standard in terms of design optimization, electroplating treatment, and structural stability, and have even greater advantages in local rapid customization and supply response speed.

The comprehensive test results show that domestic connectors have reached the level of performance stability, signal integrity, and environmental adaptability, comparable to imported CLIFF products. At the same time, domestic production brings market advantages such as fast supply chain response, controllable costs, and ease of customization. For critical parts with stringent functional requirements, it is still recommended to maintain a combination of imported replacement and domestic solutions, ensuring both performance and stability on one hand, and cost efficiency on the other.
