FAQs
The UTS78D3AP32 uses a jam nut receptacle with a 1/3 Bayonet coupling and no backshell option. Align the PCB pins with the 3 mating contacts, tighten the jam nut to seal, and confirm the orientation is correct for the N catalog design. This simplifies mounting in tight panels while maintaining IP68 sealing.
This connector provides a 7 A current rating and accommodates voltages up to 250 V, with an operating temperature range of -40 °C to 105 °C. These specs support reliable performance in automotive, industrial automation, and outdoor equipment under demanding conditions.
Yes. It is rated IP68 and designed for harsh environments, including exposure to moisture and UV. The corrosion-resistant gold-plated PCB contacts and rugged plastic shell are intended to withstand washdown, basic chemical exposure, and long-term outdoor use.
The UTS78D3AP32 carries UL 1977, CSA-C22.2 No.182.3, and IEC 61984 compliance, with RoHS exemption 6.c. These certifications help support regulatory compliance in many automation, machinery, and electrical systems.
With a mating cycle rating of 250, this connector supports longer service life between replacements in high-cycle applications. Its sealed design reduces ingress-related maintenance, lowering downtime and lifecycle costs in critical automation lines.
