Reichle connector

from Wikipedia, the free encyclopedia
Adapter to RJ11

Reichle connector is the slang term for the former six-pin Swiss telephone connector of the type TT87 and TT89 (also T + T87 and T + T89 ). TT89 refers to the angled plug , in which the wires of a ribbon telephone cable can be pressed using insulation displacement technology without tools, while TT87 is the straight plug in which the contact pins have to be attached using a special tool. TT87 occurs primarily on cables that are sold as assembled. The corresponding telephone socket is with TT83 or T + T83 designated.

They are named after the company that developed them, Reichle & De-Massari AG.
