The wide range of available options with Molex modular jacks allows for hundreds of solutions from basic single port to shielded multi-port with light pipes. Users can choose from right angle or vertical configurations, shielded and unshielded, Cat 3, Cat 5, and Cat 5e performance, and either through-hole or surface mount. All of Molex’s products are designed with 50 micron gold plating (1.27 µm) to ensure durability and the best contact surface for the mating plug. Molex also offers a novel RJ11 keep-out feature for their RJ45 jacks that prevents accidental insertion of an RJ11 plug into an RJ45 housing for environments that may use legacy equipment with RJ11s as well as RJ45 connectors.
