Feature: IP68/IEC sealing and jam nut receptacle design ensures robust ingress protection in wet, dusty, and washdown environments. Business Impact: Reduces field failures and maintenance costs, extends service intervals, and minimizes downtime. Application: Outdoor enclosures and machinery exposed to moisture, oil, and vibration. Feature: Three PCB contacts with gold plating improves corrosion resistance and low contact resistance over the lifecycle. Business Impact: Higher reliability, stable signal integrity, and lower replacement rates. Application: Control panels with tight space and PCB-mounted interfaces. Feature: 1/3 Bayonet coupling provides quick mating/demating and strong vibration resistance. Business Impact: Faster servicing and reduced tool time, improving maintenance efficiency. Application: On-site servicing in rugged industrial settings. Feature: Operating temperature range from -40 °C to 105 °C supports wide ambient conditions. Business Impact: Broadens deployment across climates and reduces the need for multiple SKUs. Application: Heavy industry, outdoor equipment, and automotive-adjacent machinery. Feature: 7 A current rating and 250 V test voltage ensure reliable power and signaling capacity. Business Impact: Enables compact, high-density interconnects without oversizing harnesses. Application: Power and PCB signal integration in compact enclosures. Feature: Jam Nut Receptacle with Neoprene insert and plastic shell keeps weight low (7.2 g) and simplifies mounting while maintaining environmental resistance. Business Impact: Lower weight and simplified installation, reducing overall system weight and labor. Application: Lightweight, compact control panels and field devices. Feature: No backshell option requires careful EMI considerations, but delivers a clean, compact seal. Business Impact: Lower part count and cost; for EMI-sensitive designs, plan alternative shielding strategies. Application: Tight-environment installations where space is at a premium and backshells are not feasible.
