FAQs
The UTS7128SM20 uses a threaded receptacle with a 1/3 Bayonet coupling for secure mating. It supports crimp contacts and offers last mate first break capability as an option. Note there is no backshell accessory. In practice, secure mounting and clean mating surfaces are essential for achieving IP68/69K protection and reliable, vibration-resistant connections in rugged settings.
This connector provides a 10 A current rating with test voltages of 80 V IEC and 500 V UL/CSA. It houses 8 contacts and maintains performance across a broad operating range, making it suitable for sensors, actuators, and general automation circuits while ensuring safety and regulatory compliance.
Yes. With IP68/IP69K sealing, UV resistance, and salt spray resistance up to 500 hours, the connector maintains integrity in outdoor, wash-down, and dusty environments. Its compact form factor and robust materials reduce long-term maintenance needs for outdoor automation, conveyors, and agricultural machinery.
The unit complies with UL 1977, CSA-C22.2 No. 182.3, and IEC 61984, supporting regulatory alignment across North American and international markets. This makes it easier to certify equipment and reduces time-to-market for automated systems deployed in regulated industries, while the UL94 V0 flammability rating adds safety for consumer or industrial installations.
The UTS7128SM20 delivers up to 250 mating cycles under typical conditions, with a operating temperature range from -40 to 105 °C and 500-hour salt spray resistance. Optional features like last mate first break provide serviceability in field swaps, helping to minimize downtime and extend equipment uptime in challenging environments.
