Choose the right Ethernet filter

Add in-line noise filtering to your Ethernet connection. Choose the model for the data rate and construction your installation needs.

Each filter uses standard RJ45 connections and fits between Ethernet patch cables.

Match the filter to your connection

Filter Data rate Connection Choose it for
Standard Ethernet filter 10 / 100 Mb/s RJ45 at each end Compact in-line filtering for 10/100 Ethernet data connections.
Cased Ethernet filter 10 / 100 Mb/s RJ45 at each end The 10/100 filter in an enclosure for easier handling and integration.
KEN-137 12 V passive PoE filter Two data pairs; no Gigabit Recommended DC application: regulated 12 V; 100 mA total with external current limiting Spare-pair power filtering on pins 4/5 and 7/8, plus separate data-pair filtering. No IEEE PoE or 24 V / 48 V passive PoE.
Gigabit Ethernet filter 10 / 100 / 1000 Mb/s RJ45 at each end The dedicated filter for Ethernet data links operating up to 1 Gb/s.

The standard and cased models are for 10/100 Mbps Ethernet. Choose the dedicated Gigabit model for 10/100/1000 Mbps data links. The KEN-137 filters two data pairs and a separate spare-pair DC feed. Its recommended DC application, based on the circuit and component ratings, is regulated 12 V passive power with external current limiting to 100 mA total, including start-up and current-limit tolerance. Keep supply tolerance and transients below 20 V. It does not support Gigabit, IEEE 802.3af/at/bt PoE, 24 V / 48 V passive PoE, or power on the data pairs.
