| Filters for Communication Lines Filter Boxes Series/Type: B84299G Date: January 2004 (c) EPCOS AG 2004. Reproduction, publication and dissemination of this data sheet, enclosures hereto and the information contained therein without EPCOS' prior express consent is prohibited. Purchase orders are subject to the General Conditions for the Supply of Products and Services of the Electrical and Electronics Industry recommended by the ZVEI (German Electrical and Electronic Manufacturers' Association), unless otherwise agreed. Filters for communication lines Filter boxes B84299G Models Filter boxes for max. 52 communication line filters with 1 pair or 2 lines Filter boxes for max. 12 communication line filters with 10 pair or 20 lines Features The box is suitable for a mixed complement. A cable that simultaneously carries switching signals, communication signals and DC power, for example, can be split to separate filters for optimum signal transmission plus high stopband attenuation. Only one RF-tight connection is needed on the shielding wall. The split cables are protected by the box.

Unused holes are sealed off by RF-tight screw plugs, which can be removed for later filter additions. On each side of the box there are terminal strips for attaching the filter lines, and 3 cable inlets with the thread size of PG 29. Matching cable glands can be screwed in here using reducer rings if necessary. Ex works the filter box comes with 2 glands of size PG 29 for cable diameters of 23 to 28 mm. At the front end the filter box can be connected to the shielding wall with maximally 3 connector fittings with nominal width of 25 mm. Other cable inlets are available upon request. 3 Filters for communication lines Filter boxes B84299G 26 slots = 26 pairs / 52 lines Ordering code: B84299G0126A...

The shielding wall has 6 or 12 rectangular cutouts for screwing in the filters. Unused cutouts are sealed off by RF-tight dummy panels, which can be removed for later filter additions. On each side of the box there are terminal strips for attaching the filter lines, and 4 cable inlets with the thread size of PG 29. Matching cable glands can be screwed in here using reducer rings if necessary. Ex works the filter box comes with 4 glands of size PG 29, PG 29/PG 21 reducer rings and PG 21 cable glands. On the rear the filter box can be connected direct and RF-tight to the shielding wall. 7 Filters for communication lines Filter boxes B84299G 6 slots = 60 pairs / 120 lines Ordering code: B84299G0114A...
