FAQs
The UTS78E3SM12 uses a threaded receptacle with a 1/3 bayonet coupling. It is designed without a backshell option, which simplifies installation in tight spaces. This combination provides reliable sealing and straightforward assembly, ideal for compact control panels and field wiring where space is at a premium.
It features three solder cup contacts configured in a 3‑cavity layout with a 7 A current rating and up to 250 V. The socket (female) contacts are delivered loaded, enabling efficient harness assembly. This makes it suitable for low-power control circuits, sensors, and actuators within industrial equipment.
Yes. The UTS78E3SM12 operates from -40 °C to 105 °C and provides IP68 sealing in unmated conditions, along with resistance to oil, basic and acid baths, UV exposure, and other environmental stressors. Its robust material choices and environmental resistance make it suitable for outdoor and harsh industrial installations.
This receptacle aligns with UL 1977, CSA-C22.2 No.182.3, and IEC 61984 standards, with RoHS exemption 6.c. Compliance support helps ensure regulatory acceptance across North America and Europe, reduces supplier risk, and streamlines certification processes for automation projects.
Absolutely. The 1/3 bayonet coupling, three-position layout, and compact footprint enable rapid mating and unmating, minimizing downtime during maintenance or expansions. Its small size (21.3 mm depth, 24 mm x 24 mm footprint) and lightweight design (7.4 g) simplify panel integration and inventory management for service teams.
