FAQs
To install, align the 4-position receptacle with the mating plug, ensuring the W orientation and thread engagement for the threaded receptacle. The unit uses a 1/3 bayonet coupling for secure mating and does not require a backshell. Use appropriate sealing surfaces to maintain IP68/69K protection in unmated and mated states. Verify clearances around the 21.3 mm depth and 24 mm shell to prevent stress on the solder cups.
The UTS78E4SWM12 is rated for 7 A current (per UL, IEC, CSA) and supports up to 250 V in standard configurations. The IEC specification notes a 32 V rating, while CSA/UL specify 250 V. This makes the connector suitable for power and control signals within industrial automation equipment, panels, and field devices.
Yes. The connector provides IP68 protection in unmated conditions, with resistance to oils, fuels, and UV exposure. Its operating temperature range of -40 °C to 105 °C supports use in extreme environments, and the stainless-like neoprene insert offers additional chemical resistance, delivering reliable performance in outdoor, wash-down, and harsh industrial settings.
This receptacle complies with UL 1977, CSA-C22.2 No.182.3, and IEC 61984, and carries RoHS exemption 6.c. These certifications validate electrical safety, compatibility with global industrial standards, and reduced hazardous material content. For engineers and procurement teams, this ensures regulatory alignment, easier supplier qualification, and smoother integration into certified equipment and systems.
With 250 mating cycles and a compact, lightweight design (7.6 g), the UTS78E4SWM12 minimizes downtime during field service and reduces total cost of ownership. The absence of a backshell option simplifies inventory and installation in space-constrained enclosures, while robust sealing and material choice help lower ongoing maintenance costs through fewer ingress-related failures.
