Compatibility and Applications
Compatible Equipment: 306E2/307E2 mini excavators, 226B3/236B3 skid steer loaders. Used for centralized electrical system wiring connection, compatible with boom, stick, or vehicle body electrical nodes.
Application Scenarios: Installed at the convergence point of equipment electrical wiring, it connects the signal and power lines of sensors, solenoid valves, controllers, etc., providing line protection and stable signal transmission. Suitable for complex working conditions such as outdoor excavation and loading, preventing line damage, water ingress, and short circuits.
Compatible Usage: Uses with M12 waterproof plug, sealing ring, and mounting bolts for quick wiring and reliable protection.
Installation and Maintenance Points
Installation: Fix in a dry, vibration-free location, tighten with M6 bolts (torque 8-10 N·m). Before connecting the wiring, check that the interface sealing ring is intact. Connect the wires according to the terminal numbers. After wiring, tighten the interface nut to ensure waterproofing.
Maintenance: Check the junction box seal every 200 hours, clean surface oil and dust, and inspect terminals for looseness or oxidation. Address any abnormalities promptly.
Replacement: Disconnect the power supply before disassembly. Remove the junction box, replace with the new part, and rewire according to the original terminal numbers, ensuring correct wiring connections and proper sealing.
