Question

There are ________ number of pins in RJ11 connector.

• A. 8
• B. 6
• C. 14
• D. 16

Hint:

Do not confuse RJ11 with RJ45: - RJ11 is smaller, has 6 pins, and is used for telephone lines. - RJ45 is larger, has 8 pins, and is used for Ethernet computer networking cables.

Answer 1

The Correct Option is B

Step 1: What is an RJ11 Connector?
An RJ11 (Registered Jack-11) is a standardized physical interface used to connect single-line telephone instruments to local telephone networks.

Step 2: Analyzing the Pin Configuration:
The RJ11 connector features a compact plastic plug:

• It has 6 physical slots (pins) or positions, which is technically referred to as a 6P (6-Position) connector.
• Although it has 6 physical slots, only 2 or 4 of them are loaded with metal contacts for a standard single-line telephone (referred to as 6P2C for 2-conductor or 6P4C for 4-conductor wiring).

Step 3: Conclusion:
Since the RJ11 physical connector body contains 6 pin slots, option (B) is correct.
