FROM INTERFACE TO ASSEMBLY
Choose by the connection your equipment needs.
Start with an existing mating reference, or define the space, circuits and operating conditions for a new connection.
Restricted installation space
Compare Micro Circular, Low Profile, Micro Low Profile and Nano against the complete installed envelope. Include the cable bend and access for mating.
Power or signal duty
Define voltage and current for power circuits; protocol, data rate and shielding for data; impedance and frequency for coaxial signals. Review the whole cable path.
Working depth and mating conditions are separate requirements.
State maximum operating pressure or depth, immersion duration and temperature. Also state whether the connection must be made underwater. Check the exact connector, cable and terminations together; a reference pressure-test figure is not a working-depth rating for a supplied assembly.
