IP68/IP69K sealing and jam-nut receptacle provide reliable ingress protection, reducing field failures and downtime in harsh environments such as outdoor automation, construction equipment, and mobile machinery; the result is longer service intervals and lower maintenance costs. The 1/3 bayonet coupling enables fast, tool-free mating with secure retention, cutting installation time and minimizing misalignment risks that can cause intermittent connections. With three gold-plated solder cup contacts, this receptacle delivers stable, corrosion-resistant conductors for sensor and actuator wiring, while the neoprene insert improves sealing under vibration and temperature swings. The aluminum nut ensures robust mechanical compatibility with Souriau UTS shells and reduces mounting stress. A wide operating range (-40 °C to 105 °C) and 7 A current rating support reliable power and signal transfer in extreme conditions, backed by a 250 mating cycle life. At 7.3 g and a compact 25.3 mm length, it adds minimal weight and footprint, simplifying panel layouts and harness designs and lowering inventory complexity. Salt spray resistance (500 hours) and UV resilience further extend service intervals in exposed installations, improving overall return on investment for industrial automation projects.

FAQs
Plan for a jam-nut mounting with a 24 mm shell footprint and 25.3 mm depth. The unit uses a 1/3 Bayonet coupling and is designed for three solder cup contacts; note that a connector accessory must be ordered separately.
Current rating is 7 A (UL/IEC), test current also 7 A (CSA/IEC/UL), and test voltage is 250 V (CSA/UL) with 32 V (IEC). It features three gold-plated solder-cup contacts for reliable, corrosion-resistant connections.
Yes. It provides IP68 protection (unmated conditions), operates from -40 °C to 105 °C, has salt spray resistance (500 hours), UV resistance, and vibration tolerance, making it well suited for outdoor automation, rugged machinery, and sensor networks.
The part complies with IEC 61984, CSA-C22.2 No.182.3, and UL 1977, with RoHS exemption 6.c. These certifications support regulatory compliance across global projects and help ensure safe, interoperable deployments in industrial settings.
The connector’s durable IP68/69K sealing, 250 mating cycles, and lightweight design reduce downtime and replacement costs. Quick mating and robust contacts lower field labor time, while long-term resistance to corrosion and environmental factors extend service intervals, improving overall ROI for automation projects.
