Key factors: Cable outer diameter (must fit connector), number of conductors (must match connector pins), conductor size (must handle your current), jacket material (must suit your environment). We offer cable assembly service &#8211; send us your cable specs or samples and we&#8217;ll match the right connector. Popular cable types: Polyurethane (flexible, ROV), TPE (general purpose), Polyethylene (deep water). Tell us your cable OD and we&#8217;ll recommend compatible connectors.<\/p>\n<\/div>\n<h2>Cable-Connector Matching Guide<\/h2>\n<h3>Key Matching Factors<\/h3>\n<h4>1.
