EPX® Rectangular Modular Connectors

Radiall EPX® Rectangular Modular Connectors are space-saving with high-density inserts and stackable shells. The EPX connectors are modular and expandable with lightweight shells from size 1 to multi-gang versions. Radiall EPX inserts can cover various contact technologies including signal, power, quadrax, and fiber optics. The backshells of these heavy-duty power connectors are available in aluminum and composite versions. The insert of these connectors can be easily installed and removed from the shell. The EPX shell can accommodate a wide variety of inserts for signal, power, coax, data bus, fiber-optic, and high-frequency BMA contacts. The EPX rectangular modular connectors provide an excellent trade-off between the number of available contacts and the space used. These connectors meet the most stringent requirements of the OEM and are ideal for various applications including disconnect panel.
