Feature → Business Impact → Application: Metal shell in zinc alloy with nickel plating provides superior corrosion resistance and durability in outdoor or exposed industrial settings, reducing replacement costs and downtime. This translates to longer service life in heavy equipment and mining applications where harsh environments are common, enabling more reliable field deployments for automation projects. Feature → Business Impact → Application: 26 contact positions in a square flange receptacle with crimp contact type and shielded design delivers compact, high-density interconnects for control panels and machine tools, improving wiring efficiency and reducing panel footprint in automotive manufacturing lines. Feature → Business Impact → Application: 1/3 Bayonet coupling and IP67/IP68 rating ensure a watertight, vibration-resistant connection, minimizing maintenance and keeping critical sensors and actuators online in railways and industrial plants. Feature → Business Impact → Application: Operating temperature range from -40 °C to 105 °C expands usable environments, allowing equipment to function in cold climates and high-heat zones without spare connectors, which reduces catalog complexity for system integrators. Feature → Business Impact → Application: 500 mating cycles and 4 A current rating deliver repeatable connections with predictable life cycles, supporting higher uptime in assembly lines and automation equipment that requires frequent disconnections and re-connections. Feature → Business Impact → Application: Shielding and polyamide insert material provide EMI protection and robust dielectric performance, ensuring signal integrity in noisy factory floors and mixed-pibre systems, which is critical for programmable logic controllers and safety interlocks.

FAQs
UT0W01626SZH is designed as a 26-contact square flange receptacle in the Souriau UTO family and uses a 1/3 Bayonet coupling. It fits compatible UT0-series shells and mounting arrangements, with shielding to maintain EMI performance. For best results, verify flange hole patterns and nut material compatibility (aluminium) for secure mounting on equipment frames.
The connector supports a 4 A current rating (IEC/UL) and a test current of 3 A (CSA). It is rated for up to 40 V IEC and 250 V variants (CSA/UL) and offers up to 500 mating cycles, ensuring reliable reuse in maintenance-heavy environments while maintaining performance across temperature extremes.
Yes. The unit provides IP67 protection, with a 96-hour salt spray resistance, and operates from -40 °C to 105 °C. This makes it suitable for outdoor machinery, mining equipment, rails, and marine-adjacent installations where exposure to moisture and contaminants is common.
Consider flange mounting alignment, the aluminium nut material, and the available space around the 31 mm width and height. Ensure shielded wiring feasibility and proper crimp contacts for reliable signal/power transmission. Check the 25.2 mm depth to confirm enclosure cavity clearance and mating clearance for the 1/3 Bayonet coupling.
The connector lists UL 1977 compliance and overvoltage/pollution safety alignments, along with RoHS/REACH and UL94 V0 flammability. These certifications help qualify the part for industrial automation, energy, and transportation sectors where regulatory adherence is critical.
