FAQs
Install the jam-nut receptacle into the panel hole, align the 24 mm x 24 mm footprint, and secure with the jam nut. The unit uses a 1/3 bayonet coupling for quick mating and does not require a backshell. For PCB mounting, insert the 3 gold-plated contacts and ensure correct orientation (W) before mating with the corresponding plug.
The UTS78D33PW32 is rated for 7 A per UL/IEC/CSA and supports up to 250 V. It is designed for three PCB contacts with gold plating, suitable for standard automation loads and signal/power interfaces in controlled industrial environments.
Yes. The connector provides IP68 sealing and IP69K capability in unmated conditions, plus resistance to oils, gasoline, mineral oil, and UV exposure. These features suit wash-down areas, outdoor machinery, and harsh industrial environments.
Key compliances include IEC 61984, UL 1977, RoHS exemption 6.c, and CSA-C22.2 No.182.3. These standards support safety, environmental compliance, and suitability for regulated industrial applications.
With 250 mating cycles, salt spray resistance (500 hours), and corrosion/UV durability, the UTS78D33PW32 reduces replacement frequency and downtime. Its compact footprint and quick-mating design further reduce installation time and long-term maintenance costs in automated lines.
