M8-3 Panel-Mount Receptacle, Right-Angle Solder, IP67
It carries a 4 A per-contact rating at 60 V, with gold-plated mating contacts and a nickel-plated zinc die-cast shell that provides full shielding. The IP67 rating means the mated pair resists dust ingress and temporary water immersion — suited for washdown environments, sensor junctions on conveyor lines, and outdoor telecom cabinets. Right-angle solder termination and a panel-mount bulkhead flange let this connector sit flush against a panel wall or board edge, with the board lock anchoring it through reflow and vibration.
The 4 A per-contact rating at 60 V is typical for M8 sensor/actuator power and signal circuits. The limiting factor is the pin density within the M8-3 shell — at 3 positions the per-contact current is generous for the shell size, so derating above 85 °C is the real constraint, not the contact itself.
IP67 Sealing and Board Lock for Harsh Environments
The IP67 ingress protection (dust-tight, waterproof) is achieved through the threaded coupling and bulkhead seal — the O-ring seals at the panel face, not the thread. This makes the 2-2172091-2 a candidate for applications where washdown or condensation is routine: food processing line sensors, outdoor camera mounts, or coolant-level probes on machine tools.
