UK Plugs

RJ45 Connector Manufacturer

If you have arrived here holding a plug with the latch on its side, you are holding a British telephone plug and not an RJ11, whatever the listing you bought it from claimed. That distinction is the whole reason this page exists. Prounta manufactures the BT 631A plug — six positions, six gold-plated contacts, moulded to British Standard BS 6312 — for cable assembly houses, telecom wholesalers, alarm and lift installers and distributors serving the UK, Ireland and Commonwealth markets. This page explains exactly what the part is, how it differs from the American connectors it is constantly confused with, and how to specify it correctly the first time.
