Molex RJ45 Magnetic Jacks


Molex RJ45 Magnetic Modular Jacks incorporate wire-wound components (magnetics) in standard RJ45 jacks. In addition to connectivity, magnetic jacks provide signal conditioning, electromagnetic interference (EMI) compliance and electrical isolation. Magnetic modular jacks support Fast Ethernet (10/100 Base-T) and Gigabit (1000 Base-T) Ethernet applications. RJ45 Magnetic Jacks are available in Power over Ethernet (PoE) versions that support PoE functionally while allowing designers to manage power and ganged versions for high port-count gigabit switches and routers.

New! PDJack™ is the first integrated PD (Power Device) Jack in the market to combine PoE+ PD controller circuitry and bridge rectifiers with gigabit magnetics in one connector for a complete drop-in, single port solution.

Gigabit PoE

The single-port 85789 Series Gigabit PoE (Power over Ethernet) Enabled RJ46 Magnetic Jacks offer integrated gigabit PoE magnetics and multiple LEDs. The design includes four extra pins, allowing the designer to connect PoE circuitry to power PDs (Power Devices), such as security cameras or VOIP phones. This connector can also deliver power from a PSE, (Power Sourcing Equipment) such as a switch or router. The 85789 Series meets the PoE Plus 30Watt IEEE802.3at standard with backward compatibility to the 15Watt IEEE802.3af standard.

NEW! PDJack™

Molex POE Plus RJ45 Magnetic PDJack™ is the market's first integrated PD (Power Device) Jack to combine a PoE+ PD controller and bridge rectifiers with gigabit magnetics in one connector for a complete drop-in, single port solution. PDJack simplifies PoE Plus implementation for any network device and achieves considerable PCB space savings. Positioned on the PCB, the PDJack provides 54 volt power of up to 25.5 watts. Two pins are for output power and standard signal pins provide Ethernet connectivity. Additional pins allow power-up of an external DC to DC converter. The PDJack manages all the communications with the switch/router PoE controllers, negotiating power requirements and managing safe power-up and power down of PD devices such as IP phones, IP cameras, wireless access points, control panels, vision systems and point of sale (POS) units.

Features and Benefits

PoE integrated circuit included

All PoE functionality achieved within connector; no PoE circuitry required on customer PCB. No PoE knowledge or experience required by the customer. Up to 75% board space saving vs. discrete solutions.

Bridge rectifiers to accommodate all Power Sourcing Equipment (PSE) types

As required for IEEE compliance to support functions of all PoE PSE types

Detection and classification circuitry fully IEEE802.3at compliant

Eliminates complex design and testing resulting in faster time-to-market, reduced investment, lower direct and associated purchasing and production costs

Robust ESD and EMI (electro-magnetic interference) design

Fully shielded connector with integrated electro-static discharge (ESD) protection

Efficient thermal design

Suitable for wide operating temperature range and passive airflow environments
