ERNI Offers Modular Jacks to Support Power-over-Ethernet

ERNI expands its broad line of Integrated Magnetic Modular Jacks with new versions supporting remote power applications (Power over Ethernet, PoE). For applications that meet IEEE802.3af requirements (PoE) and transferring up to 15 watts of power these Modular Jacks with integrated magnetics are equipped with either hubs or circuitry for DTE’s (Data Terminal Equipments) that can accept power over either data pairs or unused pairs.

These provide the ability to supply power along with the data on the CAT5 cable up to 100 meters. It eliminates the need for additional external power supplies and allows the hub to provide 48VDC at up to 350mA. This voltage can then be converted to 5 or 3.3V to power up the PHY and DTE circuits. The PoE Modular Jacks are ideal for applications like VoiP phones, wireless base stations, remote cameras, etc.

The new Modular Jacks with integrated magnetics for 10/100 are available in right-angle single-port or ganged 1x2 and 1x4 configurations. The Modular Jacks have shields with panel flanges on top and on both sides for effective grounding. Integrated LED’s are available in a variety of colors.

The ERNI Modular Jack family with integrated magnetics can be customized to meet the needs of the circuit design. Connectors for all Ethernet data rates are available. The ModJacks are based on a patented design and specified to meet FCC and IEEE 802.3 requirements for voltage isolation and performance. The products are offered in single port, multi-port ganged, vertical and tab-up configurations. Also versions with LEDs are available.
