FAQs
This receptacle is a jam-nut, backshell-free connector with a W orientation and 1/3 Bayonet coupling. It is designed for panel mounting where space is tight and sealing is essential. With an IP68/69K rating, it tolerates immersion and washdowns, while the 3-pin PCB layout and gold-plated contacts support reliable signal and power transfer in vibration-prone automation panels.
It features three PCB contacts loaded for immediate seating, gold plating for corrosion resistance, and a compact 25.3 mm length with 24 mm width/height. The 7 A rating and 250 mating cycles provide robust performance in automated lines, while the 1/3 Bayonet coupling enables quick mating and rework without backshell accessories.
Yes. The connector aligns with IEC 61984 and UL 1977, with RoHS exemption 6.c and CSA-C22.2 No.182.3 noted for reference. It also carries IP68 protection and UV/oil resistance characteristics, making it suitable for a wide range of industrial applications while meeting regulatory and environmental requirements.
Applications include outdoor machinery, wet process lines, packaging equipment, and mobile or remote automation devices. The IP68/69K rating, plus resistance to mineral oil, UV exposure, and temperature extremes, ensures continued operation in challenging environments and reduces unplanned downtime due to ingress or corrosion.
The combination of rugged sealing, gold-plated contacts, and high vibration tolerance reduces contact failures and maintenance cycles. With 250 mating cycles and a broad operating temperature range, facilities can expect lower downtime, fewer gasket replacements, and longer service life in harsh environments, translating to boosted uptime and predictable maintenance budgeting.
