IP68/69K waterproof performance in unmated condition protects electronics during washdowns and harsh weather. The three gold-plated PCB contacts ensure low contact resistance and corrosion resistance, supporting consistent signal integrity. Ideal for automation panels and outdoor machines, this feature reduces field failures and promotes longer service intervals. 1/3 Bayonet coupling with jam nut receptacle simplifies installation in tight panels. Locking is robust and quick, reducing assembly time and field retries. Current rating of 7 A and test voltage up to 250 V (32 V IEC) provides versatility for control circuits and sensing networks in a compact footprint. This supports both power and signal paths in single connectors, lowering harness complexity. Operating temperature range of -40 to 105 °C accommodates extreme industrial climates. With neoprene insert, plastic shell, and UV resistance, the connector withstands aging and environmental exposure while maintaining seal integrity. Salt spray resistance of 500 hours reinforces durability in coastal or humid environments. The L3 layout and 8 mm shell size enable efficient panel integration and reuse of existing mounting practices. Certifications such as UL 1977, CSA-C22.2 No.182.3, IEC 61984, and RoHS exemption 6.c help meet global regulatory requirements and supplier specifications.

FAQs
To install, insert the PCB socket into the panel cutout, align the orientation keying (X), and tighten the jam nut from the exterior. Since there is no backshell accessory, focus on proper thread engagement for the nut and ensure the 3 PCB contacts are seated before final torque. Verify IP68 sealing after installation and perform a continuity check across all three contacts.
The connector uses three gold-plated PCB contacts with a 1/3 Bayonet coupling, offering low contact resistance and reliable signal transfer in automated control circuits. The neoprene insert and plastic shell provide environmental resistance, while the 25.3 mm length and 24 mm width support compact, panel-friendly mounting. These features translate to easier design-in and reduced likelihood of field failures in automation panels.
The UTS78D3SX aligns with UL 1977, CSA-C22.2 No.182.3, and IEC 61984, reflecting suitability for safety-critical industrial use. It also complies with RoHS exemptions (6.c), and offers IP68 sealing for unmated conditions. These certifications help meet regulatory requirements and support qualifications for certified equipment and machinery.
Operating from -40 °C to 105 °C, the UTS78D3SX withstands extreme industrial environments. The neoprene insert and UV-resistant plastic shell resist aging, while the design provides resistance to mineral oil, basic bath, gasoline, and salt spray for up to 500 hours. These properties ensure long-term reliability in outdoor and washdown settings.
The junction supports up to 250 mating cycles, offering a reliable lifecycle for frequent maintenance or panel reconfigurations. Gold-plated PCB contacts reduce wear and corrosion, while robust IP68 sealing minimizes preventive maintenance related to moisture ingress. For maintenance planning, this translates to fewer rework events and predictable downtime in automated lines.
