Hammond 1594RFIDBK 132 x 66 mm Shielded Conductive Plastic Enclosure

The 1594RFIDBK is a long, narrow thick-wall enclosure from the 1594RFI series, molded in black conductive plastic for EMI/RFI shielding applications. Its 132 x 66 mm footprint suits longer circuit boards and interface electronics where a designer wants a shielded housing that looks and handles like a standard plastic box.

Shielding comes from the material: a conductive compound of stainless steel fibers and flame retardant ABS plastic that carries a UL flammability rating of 94V-0. The walls average 0.13 in (3.3 mm) per series data, with 3.10 mm on the drawing, and the finish is a matte textured black. An independent test report in the series documentation evaluated shielding effectiveness to VG 95373 P15 on boxes measuring 131 mm x 66 mm x 55 mm with 3.3 mm walls, one of which was a plastic box loaded with 10 percent stainless steel.

The ordering table lists 5.20 in (132 mm) long, 2.60 in (66 mm) wide and 2.17 in (55 mm) deep, and the part page gives a nominal 5.2 x 2.6 x 1.7 in (132 x 66 x 43 mm). The drawing shows a 131.50 x 66.30 mm box, a narrowest inside dimension of 56.97 mm and an inner box height of 49.30 mm. It ships at 0.33 lbs (0.15 kg).

The countersunk lid on the 1594RFIDBK is secured with four M3-0.5 x 18mm long Philips machine screws threaded into integral brass bushings; spares are part number 1594MS100 (pack of 100). The enclosure is designed to meet IP54 and is REACH and RoHS compliant. It is brittle, similar to phenolic, so avoid high impact use, and treat it as a metal enclosure because conductive plastic is not an insulator.
