Verify rated current/voltage, insulation resistance and contact resistance to ensure they meet the original connector's specifications.
Match IP protection rating (e.g., IP67/IP68) and locking mechanism (threaded/bayonet) with the application environment.
Ensure pin assignment and wiring definition are identical to avoid electrical misconnection and equipment damage.
Confirm equipment interface compatibility to avoid mechanical interference; check cable exit direction and strain relief compatibility.
Technical Note: After replacement, conduct electrical testing (continuity, insulation resistance) and mechanical durability testing to validate the performance of M16 connectors in actual operating conditions.
