Selecting the correct connector requires matching specifications with your operational needs:
· Determine the voltage and current requirements for power transmission
· Assess the environmental exposure conditions (dust, humidity, vibration, temperature) of your working site
· Choose proper housing material and surface treatment based on corrosion and impact demand
· Select suitable locking mechanism to ensure anti-loosening performance for high-vibration scenarios
· Verify pin count and transmission type compatibility (weak signal, power, hybrid transmission)
· Confirm the installation type (straight or right angle) to match your equipment installation space
Gaoshiwei recommends consulting our technical engineers before bulk purchasing to ensure precise compatibility with your industrial systems.
