Keystone – Modular Keystone RJ45 Jacks for PCB and Panel Applications


Manufactured for increased durability, the Keystone RJ45 sockets can endure a minimum of 500 insertion cycles. Rated for 125VAC RMS, these jacks are fully compliant with IEEE and IEC standards. A variety of styles are available to accommodate design applications with numerous mounting and port size options.

Horizontal (right-angle) PCB modular jacks are available in thru-hole or surface mount soldering configurations. For low profile applications, request #943. For compact designs, #942 is recommended. Applications that require a deeper socket can be met by using #948. Designs for surface mount installation can utilize #944.

For devices where connectivity will be perpendicular-to-the-board, a vertical (top-entry) PCB modular jack, #949 is offered. As part of this series, Keystone is offering a panel mount modular jack, #946 which is supplied in a 2-piece locking design to simplify and secure wiring of the jack.

These Keystone modular jacks provide a reliable connection to networks. They will mate with any plug that conforms to FCC Part 68, Subpart F.
