FAQ

What are the recommended torque specifications for installing the CG1275S connector?

The manufacturer advises applying a tightening torque between 15 and 20 Newton‑meters on the threaded interface. This range ensures a secure clamping force that prevents loosening under load while avoiding over‑stress that could damage the housing or threads. Using a calibrated torque wrench during installation helps achieve consistent results and prolongs the service life of the connector.

Can the CG1275S be used in high‑temperature applications?

Yes, the steel alloy used in the CG1275S maintains its mechanical properties up to approximately 250 °C (482 °F). This temperature rating makes the connector suitable for heat‑intensive processes such as forging, extrusion, and high‑speed machining where elevated operating temperatures are common. Proper thermal management and adherence to the specified temperature limits are essential to preserve performance.

Is the connector compatible with different cable gauges?

The CG1275S accommodates a range of cable sizes, typically from 12 AWG to 20 AWG. This flexibility allows users to select the appropriate gauge for their specific power or signal requirements without needing additional adapters. The sealed entry design ensures that each supported gauge remains protected against environmental contaminants.

How does the sealed cable entry achieve IP68 protection?

The sealed entry incorporates a gasketed compression fitting that compresses around the cable sheath when tightened, creating a watertight barrier.
