A punch-down module is a single unit that houses 110 or krone-type punchdown connectors for telecommunication system distribution. Often used in telephony or datacom applications, a punch down module places wiring throughout numerous areas of one location, such as home or office. A punchdown telecommunications module commonly terminates incoming and distributes outgoing telephone lines. Cat5e and Category 6 cabling can also terminate in a punchdown patch panel with standard port designs. Panel punch-downs of solid or stranded wire are completed with a designated tool. Modules or panels with Krone and 110 punchdown connections feature insulation-displacement connectors (IDC). The electrical connector sends a blade(s) through the insulation of a cable or wire, making contact with the conductor underneath. This process eliminates stripping wire before making a connection.

Krone-Style Connectors

The Krone-style connector is a standard European/UK connector that is an option to the 110 punchdown connector. Compared to the 110s, Krone type connectors have open-ended contact slots at a 45-degree angle to the wire. Copper wire is punched down into the slots. A krone-style punch down tool can connect wires to the IDC contacts on module or patch panel outlets.

Module with 110 Punchdown Connectors

Within a cabling system, a module with 110 punchdown connectors provides the housing for sets of wires. The 110 type of connector can cut through insulation as it is used to terminate twisted pair cables. A single 110-style punchdown module can distribute wiring to a series of outlets throughout one location. Cable runs can terminate in modules with 110 connectors which are on the back of patch panels. Modules are available to meet Category 5e and 6 specifications.
