The Industrial MAX® PCB modular jack features high performance connectivity housed in a robust protective shell. The jack's outer housing is made of durable, chemical-resistant, industrial-grade thermoplastic and includes a patent-pending bayonet style mating interface. A simple quarter-turn of the mating plug (sold separately), and a positive stop indicate the connector is locked and sealed against the most punishing environments.The modular jack's design has been optimized to minimize crosstalk between pairs resulting in a superior balanced signal from pair to pair. The jacks are designed to meet IEC 60603-7.
