Protection Points for Marine Propulsion Control Levers

As the "nerve endings" of vessels, marine propulsion control levers must withstand five extreme marine environmental challenges: high salt spray, high humidity, severe vibration, wide temperature range, and electromagnetic interference (EMI).

I. Core Standards and Certifications
1. IP Rating: IP56
2. General Standard: Complies with IEC 60945 requirements for marine electronic equipment
3. Quality Certification: Passed the Quality Management System Certification of China Classification Society (CCS)
------------------------------------------------------------------------------
II. Core Product Protective Design
1. Structural Sealing: Adopts silver-impregnated sealing rings to enhance wear resistance and sealing performance
2. Material Protection: 6061 aluminum alloy housing with black powder coating, copper alloy transmission gears
