The 1596B105-5 is a pack of 5 black plastic potting boxes, each one one of the larger boxes in the series at 75 x 50 mm, with a 35 mm depth. Each box is a one piece molded cup with no lid, designed for potting box applications, so electronics builders, OEM production teams and repair technicians can encapsulate a larger circuit board, power supply section or transformer in compound and have a neat, consistent outer shell. Buying the 5-pack keeps identical boxes on hand for small production runs.

The box is molded from black general purpose ABS plastic with a flame rating of UL94-HB and a smooth black finish. It is temperature rated from -20º to +94º C (-4º to 201.2º F), which is worth checking against the cure temperature of your potting compound. Wall thickness is 1.0 mm (0.04 in) per the series specification, matching the 1.00 mm shown on the drawing.

The part page lists the size as 2.95 in x 1.98 in x 1.39 in (75 mm x 50 mm x 35 mm). In the series ordering table the box is 2.95 in (75 mm) long, 1.97 in (50 mm) wide and 1.38 in (35 mm) deep; the drawing shows 75.00 mm x 50.00 mm, with a height of 35.10 mm on the drawing. The 5-pack ships in a bag at 0.23 lbs (0.10 kg), and the single box is available as 1596B105.

Some chemicals can damage or weaken ABS, so avoid acetone, ketones, ethers, aromatic and chlorinated hydrocarbons, thread locking compounds, cutting or tapping fluid and strong solvents, and confirm any grease or oil is plastic safe. If you need holes, cut-outs or printing, the drawing notes that enclosures can be factory modified, and solid models are available in STEP or IGES. The 1596B105-5 is REACH and RoHS compliant.
