RT00144SNH is a reference specification document for ecomate® circular multiway connectors detailing contact sizes and wire seal parameters. The document provides contact size designations (20, 16, 12, 8, and 8*) with corresponding typical wire ranges spanning from 20-30 AWG (0.50-0.05 mm) for size 20 contacts down to 8-16 AWG (10.0-1.5 mm) for size 8* contacts. Normal and reduced wire seal dimensions are specified for each contact size, with normal seals ranging from 1.6-2.6 mm for size 20 to 2.8-5.8 mm for size 8 contacts. These specifications apply to specific insert arrangements (14.3, 18-2, and 18-4) and are used for industrial applications requiring robust, durable circular connectors with IP65 to IP69K ratings. The ecomate® family supports amperage and voltage ranges up to 300A and 1000V depending on the series, making these connectors suitable for Factory Automation, Heavy Equipment, Transportation, and Entertainment/Lighting markets.
