The Series 423 M16 connectors are available with a PG11 cable outlet for cable diameters from 8 to 10 mm. In addition to the larger cable outlet, the line of cylindrical connectors also has a 4 to 6 mm and 6 to 8 mm option. All connectors are available with 7 to 24 gold-plated contacts. When properly mated, the mated pair is IP67-rated, protecting the connection from liquids and debris. An internal shielding ring provides excellent shielding against electromagnetic interference. The M16 connectors are fully mating-compatible with other M16 connectors from the company, including front- and rear-mounted panel receptacles.
