The 1594RFICBK is the mid-size enclosure in the 1594RFI thick-wall range, a black plastic box that shields its contents from EMI/RFI because the plastic itself is conductive. It is intended for engineers and integrators who want the look and handling of a plastic enclosure around a circuit that needs shielding, in a 107 x 66 mm footprint.

The body is molded from a conductive compound of stainless steel fibers and flame retardant ABS plastic, rated UL94 V-0. Series data gives an average wall thickness of 0.13 in (3.3 mm), with 3.10 mm shown on the drawing, and the surface is a matte textured black. The material is brittle, similar to phenolic, and not for high impact use.

The ordering table lists 4.21 in (107 mm) long, 2.60 in (66 mm) wide and 1.77 in (45 mm) deep; the part page lists a nominal 4.1 x 2.6 x 1.3 in (104 x 66 x 33 mm). On the drawing the box measures 106.50 x 66.00 mm, with a narrowest inside dimension of 56.67 mm and an inner box height of 39.60 mm. Shipping weight is 0.27 lbs (0.12 kg).

• Countersunk lid held by four M3-0.5 x 18mm long Philips machine screws into integral brass bushings
• Designed to meet IP54
• Replacement screws: 1594MS100, pack of 100
• REACH and RoHS compliant

Remember that the 1594RFICBK is not an insulator. Treat it like a metal enclosure, insulate it from the user, and prevent current from shorting to or through the case, since conductive plastic acts as a heating element and can produce smoke.
