RJ11 Jack

Shop LINK-PP RJ11 / RJ12 modular jacks for copper telephony and low-pin modular interfaces. This leaf lists 4P4C, 6P4C, and 6P6C jacks—tab-up, tab-down, and vertical maps, typically without integrated magnetics—built by LINK-PP for voice, modem, and control panels. Return to the parent Modular Jack hub, browse 8P8C RJ45 Jack when you need Ethernet 8-contact shells, or see Integrated RJ45 for magnetic Ethernet options. Confirm contact map (4P4C / 6P4C / 6P6C), orientation, shield style, and footprint on each product page before ordering.

Frequently asked questions

01.What is an RJ11 jack on this page?
This leaf lists LINK-PP modular jacks for RJ11 / RJ12 copper telephony and low-pin interfaces—commonly 4P4C, 6P4C, and 6P6C—typically without integrated magnetics. See the parent Modular Jack hub for Ethernet 8P8C shells.
02.What is the difference between 4P4C, 6P4C, and 6P6C on this leaf?
4P4C uses four positions with four contacts; 6P4C uses six positions with four contacts loaded; 6P6C (often called RJ12) loads all six contacts. Match the contact map to your plug and application before ordering.
03.When should I choose RJ11 vs 8P8C RJ45?
Choose RJ11 / RJ12 maps for voice, modem, and control lines. Choose 8P8C RJ45 Jack (or an Integrated RJ45 magjack) for Ethernet networking.
04.Are TE, Molex, Amphenol, or Würth RJ11 PNs available as Compatible replacements?
Many listings map OEM RJ11 / RJ12 modular jack part numbers onto LINK-PP equivalents. Open the Compatible product page, confirm contact map, orientation, and shield style, then order the LINK-PP P/N shown.
05.What should I check before ordering an RJ11 jack?
Match positions/contacts (4P4C / 6P4C / 6P6C), tab-up vs tab-down vs vertical, multi-port count if ganged, and PCB mount style to your schematic and panel drawing. Datasheets are on each product page.
