When engineers at a Shenzhen automation company struggled with frequent relay failures in their PLC systems, they discovered an unexpected solution – the FUJI CR6L-350UL. This 3.5mm ultra-compact relay has become the industry’s best-kept secret, shrinking installation space by 40% while maintaining 10A switching capacity.
Precision Engineering in Miniature
The CR6L-350UL’s gold-plated contacts achieve 50mΩ contact resistance, crucial for sensitive measurement equipment. A medical device manufacturer reported zero failures in 200,000+ operational cycles during patient monitoring system trials.
Real-World Application: Smart Factory Upgrade
Dongguan CNC machinery plant replaced traditional relays with 320 CR6L-350UL units, achieving:
- 35% reduction in control cabinet volume
- 0.02s faster response time
- 72% lower energy consumption
Data-Driven Reliability
Third-party testing shows:
| Parameter | Result |
|---|---|
| Mechanical Life | 50 million operations |
| Dielectric Strength | 1,500V AC for 1min |
| Shock Resistance | 100G (11ms) |
With operating temperatures from -40°C to +85°C, it’s become essential in NE China’s wind power systems and Guangzhou’s 5G base stations.
