FAQs
The UTS78D2S32 uses a jam-nut receptacle with hold-down clips and does not include a backshell option. It features a 1/3 Bayonet coupling for secure mating and a 25.3 mm length with a 24 mm width/height footprint, accommodating two PCB contacts in a compact 2-cavity layout. Design supports typical panel thickness and mating orientation for reliable field service.
This connector is rated for 7 A and 250 V across its two PCB contacts, with an operating range of -40 °C to 105 °C. It’s IP68 rated in unmated conditions, UV resistant, and provides RoHS-compliant materials. Contacts are gold-plated for low resistance, and the unit tolerates vibration from 10 to 2000 Hz, suitable for industrial environments.
Yes. Its IP68/69K sealing, UV resistance, and rugged neoprene insert support outdoor and harsh indoor environments. The 2-contact PCB configuration, 7 A current rating, and wide temperature range enable reliable communication and power paths in automation cabinets, outdoor sensors, and mobile equipment.
The device complies with IEC 61984, UL 1977, and ROHS exemption 6.c, with CSA-C22.2 No.182.3 referenced for additional safety context. These certifications help meet regulatory requirements for electrical connectors used in industrial equipment and ensure supplier conformity for audits.
With 250 mating cycles and durable aluminum nut components, the UTS78D2S32 offers long service life and predictable wear. Gold-plated PCB contacts reduce contact resistance over time, while jam-nut mounting simplifies replacement. This translates to lower maintenance costs and reduced downtime in automation and field-deployed systems.
