RJ45 8P8C Unshielded/Shielded Keystone Jack

Keystone Jacks - RJ45 8P8C Unshielded/Shielded Female Connector
RJ45 8P8C Unshielded/Shielded Female Connector

The keystone jack (module) is a standardized snap-in female connector package for mounting a variety of low-voltage electrical jacks or optical connectors into a outlet (wall plate, faceplate), surface mount box, or a patch panel.

Keystone jacks have a rectangular face of 14.5 mm wide by 16.0 mm high, which held in place with flexible tabs. This allows keystone jacks to be snapped into a mounting plate with correspondingly-sized rectangular holes, which called ports.

Regardless of the type of jack they carry, all of the keystones are interchangeable and replaceable. This provides more flexibility in arranging and mounting many different types of electrical jacks in one plate or panel without requiring customized manufacturing.

Some of the keystones use a pass-through type connector, which is a jack on both the front face as well as the rear side.

Others only have a jack on the front and employ a different mechanism for hard-wiring signal cables to the rear, such as a 110 or Krone tool compatible insulation-displacement connector (IDC), tool-free (tool-less) connection.

HCI supplies patent designed keystone jacks in both solutions of Unshielded (UTP) and Shielded (STP), comply with requirements of ANSI/TIA-1096-A (former FCC Part 68) and Level A reliability requirements of IEC 60603-7 for RJ45 8-way connector

Our keystone jack family covers performance range from Category 5e (Cat 5e), Category 6 (Cat 6), to Category 6A (Cat 6A), and meets the ANSI/TIA-568-C.2, ISO/IEC 11801 Ed. 2.2 and CENELEC EN 50173-1 cabling standard.

HCI offers keystone jacks in both Component (Certified Connecting Hardware) Level, and Channel / Perm. Link Level as well to maximize customer's choices in different project scenario.
