Modular connectors - Jacks with magnetics refer to a type of connector that contains permanent magnet components in the middle of the shell and latch. The ARJM11A1-809-NN-ER4-T is a three-pole, RJ45-type connector from Amphenol Connectors. It is a female, straight connector with two latch frames at the sides that employ butterfly latch technology. This connector has a thermoplastic polyetherimide body with magnetics integrated in the middle. It has gold-plated contact pins and operates with 50/125μm multimode fibers.

Application Field

This type of connector is widely used in industrial applications, such as electrical machines, automotive, telecoms, broadcast equipment, medical instruments, precision instrumentation, and other devices requiring serial communication. It can also be used in Ethernet, RS-232, and other applications requiring data transmission. It has three wire-entrance holes for tying five conductors, or two wires for tying three conductors for communication and data transmission.

Working Principle

This connector has an integrated magnetic core, which ensures that the contact pins are held firmly in place when the plastic shells are connected. This magnetic core enables the connector to provide securely fastened connections even when subjected to vibrations or shock during usage, as it prevents the connector from disengaging due to shock or vibration. It also eliminates static charge, resulting in protection against current leakage and radio frequency interference (RFI).

The ARJM11A1-809-NN-ER4-T connector has signal pins and ground pins with a combination of twisted-pair wires. It is usually used with twisted-pair cables and comes with two latch frames at the sides, which prevent accidental uncoupling of the connection. The latch frames can be locked in place for added security and stability.

This connector has two modes for working - half-duplex and full-duplex. In half-duplex mode, it can transmit data in both directions, but in any separate direction at any given time. In full duplex mode, it can transmit data in both directions simultaneously. It is also capable of supporting both narrowband and wideband signals, allowing it to be used in various communication protocols.

This connector is also designed with temperature-resistant pins, allowing it to be used in a wide range of temperatures. It has a chrome-plated brass shell that earns it an IP67 rating, making it dust-proof and water-resistant in addition to providing rock-solid electrical connections when exposed to different environmental conditions.
