IP68/69K sealing and rugged jam-nut receptacle design deliver reliable performance in wet, dusty, and wash-down environments, reducing the risk of water ingress and unplanned downtime. This translates to improved equipment uptime and lower maintenance costs in outdoor automation, marine, and heavy-duty machinery applications, while fitting seamlessly into Souriau UTS series ecosystems. The 3 female solder-cup contacts with gold plating provide low contact resistance and long-term corrosion resistance, enabling stable signal and power delivery for sensors and actuators in harsh environments, and supporting up to 7 A at 250 V. The 1/3 Bayonet coupling offers quick, secure mating even in tight panels, while the Neoprene insert and plastic shell keep weight and thermal expansion in check for compact enclosures. With a operating range of -40 to 105 °C and 250 mating cycles, this connector supports demanding industrial cycles and field serviceability for OEMs and integrators, delivering predictable performance with reduced lifecycle risk. RoHS compliance and robust UV resistance further ensure long service life in outdoor installations and remote locations, making it a practical choice for automation deployers seeking dependable, cost-effective connectivity.
