IP68/IP69K waterproofing provides reliable protection against dust, moisture, and wash-down environments, reducing corrosion risk and maintenance costs in outdoor or harsh industrial settings. This translates to longer service life for field devices and sensors, improving uptime in automation systems and remote monitoring applications. The 3 gold-plated PCB contacts deliver low contact resistance and stable signal/power transfer for control panels and PLC interfaces, contributing to safer and more efficient panel operation while supporting hot-swappable or modular designs. The 1/3 Bayonet coupling and D3A layout enable quick, vibration-resistant mating with minimal torque, speeding installation and reducing technician time during maintenance. With a compact 25.3 mm length and 24 mm footprint, the unit fits tight panel spaces and retrofits into compact automation enclosures, lowering inventory variety and overall costs. Operating from -40 °C to 105 °C and resistant to oils, UV light, and salts, it supports outdoor and mobile equipment, reducing the need for multiple part variants. The jam-nut receptacle design, no backshell option, and X orientation simplify harnessing in limited spaces while preserving EMI integrity when paired with approved accessories. The 250 mating cycles and 7 A current rating provide predictable durability for legacy and new automation projects, aligning with lifecycle expectations in industrial environments.
