FL-3FF-S-Z Relay _ High-Load Industrial Relay _ Contact Life Test Report

FL-3FF-S-Z Military-Grade Durable Design

As a core component of the electronic control system, the FL-3FF-S-Z relay utilizes German Heraeus silver alloy contact material. After extreme temperature cycling tests from -40°C to 85°C, its contact resistance remains stable at<50mΩ. Its unique ceramic gas-sealed structure effectively isolates sulfides from the air. After five years of use in a coastal high-salt fog environment, the contact oxidation area was measured to be only 0.3mm², far below the industry standard limit of 2mm².

FL-3FF-S-Z Practical Performance in PLC Systems

In tests on a new energy vehicle battery pack production line, 200 FL-3FF-S-Z relays operated continuously for 2,000 hours with a 0% failure rate. Its 8ms response speed (compared to an average of 12ms for similar products) allows welding robots to maintain motion errors within ±0.1mm. Its specially designed anti-vibration bracket can withstand 15G mechanical shock, perfectly adapting to the vibration environment of stamping machines.

FL-3FF-S-Z Safety Certification Advantages

The FL-3FF-S-Z has passed multiple certifications, including UL508 (US), EN61810-1 (EU), and GB/T21711.1 (China). Its 5kV isolation voltage meets the DC-side isolation requirements of photovoltaic systems. It also complies with RoHS 2.0 and REACH regulations, with a cadmium content of<5ppm (the standard limit is 100ppm).
