RJ21 Amphenol Pinout Chart. Mike's PBX tips.Mike's PBX Tips. RJ21 25 Pair Amphenol Telephone Connector. A 25 pair RJ21 Amphenol cable is a necessity for many connections. This 50-pin connector interfaces for data-com trunking with the RJ21 connector, using screws to anchor into place. It is referred to as an Amphenol connector which references the connector's manufacturer.
BCM4 lines, 4 analog sets, and 12 digital sets connect to the RJ-21 Amphenol connector
50Centronics 50-Pin / CHAMP / Amphenol / RJ-21 connector; Screw terminal for each of the 50 lines, plus shield; Solder pad connection holes, three (3) per line; Supports addition of .1" pin headers; Screw terminals accomodate wire sizes from 16AWG to 26AWG; Approximate dimensions: 3.15" x 4.7" Rubber feet or DIN rail mount
RJ21 Amphenol PinoutRJ21 Amphenol Pinout The RJ21 connector is very similar to the 50-pin Centronics interface, but with screws to anchor it into place instead of bail locks. Sometimes called a "Champ" connector (referencing a series of connectors made by Amp), or an "Amphenol" connector (referencing the connector manufacturer), RJ21 interfaces are typically used for datacomm applications and support up to 25 Tip/Ring twisted pairs.
Cisco VG310 and Cisco VG320 Voice Gateways Hardware ...The X.21 connector uses a 15-pin connector for balanced circuits, and is commonly used in the United Kingdom to connect to the public data network. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.
Registered jack The connectors used for registered jack installations are primarily the modular connector and the 50-pin miniature ribbon connector. For example, RJ11 uses a six-position two-conductor connector ( 6P2C ), RJ14 uses a six-position four-conductor ( 6P4C ) modular jack, while RJ21 uses a 25-pair (50-pin) miniature ribbon connector.
RJ21, Telco, IEEEThis connector is very similar to the 50-pin Centronics interface. The biggest difference is that the RJ21 connector uses screws to anchor into place instead of bail locks. Sometimes, it is called a "Champ" connector (referencing a series of connectors made by Amp), or an "Amphenol" connector (referencing the connector manufacturer).
Solved: rjSo we've done the other way. We've bought 2xrj21 male cables (with open ends) and 2xPatch panel (Cat. 3) with 25 ports each. Then we took "rj21 color" table and "rj21 vs patch panel port numbers" table and stitched contacts with a special tool. Then we've tested all the contacts from rj21 cable to rj45 contacts and pulled wires using cable ties.

Modular Cable and RJ Connector Guide | C2GThe wiring scheme for a single line phone was identified as "RJ11", and the name stuck to describe the connector used on a phone cord. Today, RJ-11 is widely used in the connectivity industry to denote a 6-position, 4-conductor modular connector or jack. Shop 4-pin RJ-11
