Being an industry standard connector, modular jacks are extremely versatile and can be adopted by many different applications by altering the basic configuration. They can be used in almost any market with the need to connect or power a device over Ethernet. Common applications include cash registers, card readers, servers, switches, printers, medical devices, consumer set top boxes, gaming devices, and industrial control units. The growth of IoT in recent years has created a second renaissance for this connector, because a modular jack is the least expensive way to connect and power a device. This is why the modular connector will continue to be relevant during the growth of IoT in the coming years.
