Circular Connectors encompass multi-pin circular connectors and assemblies with high protection ratings, M-series types (M5, M8, m12 circular connector, M23). Characterized by threaded or bayonet locking mechanisms, they offer excellent resistance to vibration, dust, and water (up to IP68/IP69K), designed specifically for harsh industrial environments. Their advantage is providing a modular, fast, and reliable field connection solution that greatly reduces wiring time and ensures stable signal and power transmission under conditions of vibration and moisture. They are ideal for rapid deployment and maintenance of equipment. Key parameters include pin count, keying code (for mis-mating prevention), IP rating, rated current/voltage, and housing material.
