Difference Between Rj9 and Rj11 (With Table)

A registered jack (RJ) is a normalized telecom network interface for associating voice and information hardware to assistance given by a nearby trade transporter or significant distance transporter. Likewise, enrolled jacks are fundamentally named by the letters RJ, trailed by two digits that express the sort.

The essentially important thing while knowing about these connectors is the number of positions accessible on the connector and the number of contacts that are present. When there are more positions available, the connectors are essentially bigger.

Rj9 vs Rj11

The difference between RJ9 and RJ11 is that the RJ9 only comes in one type of configuration, that is, the 4P4C connection type. In contrast to that, RJ11 comprises two types of configuration. They are, namely, 6P2C and 6P4C connection types.

RJ9 connector is considered to be a 4 position, 4 conveyor plug. It generally ends on a 4 conductor telephone link. RJ9 is basically used to connect a phone handset with a phone collector. The RJ 9 is not quite an ideal choice as a connector you will go over once in a while. 

Rj11 Registered Jack – 11 is a phone interface that tends to use a link extensively of wire sets and a measured jack with two, four, or six contacts. RJ-11 is considered the basic connector for connecting a phone to the divider and the handset into the phone. RJ11 links can carry up to six wires for up to three phone lines, and their classification is RJ11, RJ14, or RJ25, relying upon the number of lines.

What is Rj9?

The Rj9 has a marginally unexpected shape in comparison to the Rj11. It has a rectangular shape. However, it is more modest than the Rj11. It is made with plastic and is additionally understood, permitting you to see the association of wires inside.

The important fact to consider about Rj9 is that the RJ 9 isn’t a connector you will run over occasionally. It is very occasions signified as the RJ10 or RJ22, and it likewise has a one-of-a-kind setup type. Due to the slight difference in the shape of Rj9, it is smaller than that of Rj11. The Rj9 has one connector type that is 4P4C, which means it contains 4 positions as well as 4 connection points, making it ideal for connecting telephone connections.

Since phone handsets/headsets don’t generally associate straightforwardly with the public organization, they don’t have a particular enlisted jack code. 

What is Rj11?

The Rj11 is a connector that has a square molded. It has a width of about 9.6mm. It has an interesting, straightforward look that permits you to see the unpredictable association of wires. It is made utilizing plastic that is solid and very firm. It is tiny and just tips the scales at 0.16 ounces.

The important fact to know about RJ11 is The RJ 11 is most regularly utilized for phone and modem associations, and it has two arrangement types. 

6 Positions, 4 conductors. 

Utilized in ADSL, Modems, Telephones, Establishing spanned association in phone lines. 

RJ11 is a simple phone association. 

RJ 11 uses just four of the six spaces accessible. 

RJ11 interfaces 4 wires. 

RJ11 is minimal and square-molded.

RJ11 is an association jack that makes a scaffold association for a solitary phone line. 

RJ11 utilizes a standard 6P2C connector for a standard phone association. It possibly utilizes a 6P4C connector when low voltage power is needed to ship off the marker light of the phone. 

RJ11 jack utilizes a level stain link, which contains two slim copper wires. 

RJ11 jack is utilized in ordinary family wire phone and modem associations.

Main Differences Between RJ9 and RJ11

  1. The Rj9 has a different shape than that of Rj11. It is rectangular, while the Rj11 is a square-shaped connector.
  2. The Rj9 has only one type of configuration that is the 4P4C connection type which provides 4 positions and 4 connection points. On the contrary, Rj11 has two types of connection points that are 6P2C and 6P4C, providing more positions and connection points.
  3. The 4P4C arrangement of the Rj9 connector makes it ideal for use in associating phone handset links. It has 3 prongs in its pleats that make it viable with both strong and abandoned wires. Whereas, The Rj11 connector is ideal for telephone lines and modem associations. The explanation for this is that it can just deal with a limit of 4 wires all at once. 
  4. Due to the rectangular shape of Rj9, it is quite smaller in size. On the other hand, Rj11 being the square-shaped connector, is comparably larger than that of Rj9.
  5. The Rj9 connector type has less versatility in connection as it only comes with one type of connector that is 4P4C. While Rj11 provides more versatility in connecting devices due to its two configuration types 6P2C and 6P4C.

Conclusion 

Rj9 and Rj11 are used as connectors for networking. It is used for organizing and infrequently low voltage lighting control applications. The thing that matters is the number of positions accessible on the connector and the number of contacts present. Where there are more positions, the connector is fundamentally bigger.

Both the Rj9 and Rj11 connectors are exceptionally fundamental in associating gadgets and communicating information from sources to gadgets. They have various attributes and are viable with various links. They likewise have extraordinary forms that make it conceivable to see the real association of the wires.

The way that the Rj11 and Rj9 are connectors implied for various applications makes it practically difficult to decide the better one of the two. Notwithstanding, the Rj11 appears to be a more conscious connector since it has two unique forms that accompany two diverse setup types. This gives the connector greater flexibility since it has a more extensive scope of links with which it very well may be associated. Hence, it stands apart as the better entertainer.
