Hammond 1551USB2TRD 50x25mm Translucent Red Abs USB Dongle Enclosure

The 1551USB2TRD is the mid-size member of the 1551USB family, a 50 x 25 mm housing with an opening for a male USB-A connector. Molded in translucent red ABS plastic, it is intended for dongles and small printed circuit boards fitted with a male USB-A connector, making it a practical choice for OEM engineers and product designers packaging compact USB devices.

The body measures 1.97 in x 0.98 in x 0.61 in (50 mm x 25 mm x 15 mm) per the part page, with the drawing showing 50.00 mm x 25.00 mm and an overall height of 15.50 mm [0.61 in]; the series ordering table lists the depth as 0.63 in (16 mm). The part page gives a maximum P.C. board length of 20.5 mm and width of 44 mm. The satin-textured cover is recessed 0.50 mm for easy label installation.

Each purchased assembly includes the box, lid and two #2 x 1/2" self-tapping cover screws, with a recommended torque of 35-43 ozf.in (25-30 cN.m). The translucent red body is one of three translucent options in the series, alongside clear and smoke. Per the series notes, red boxes ship with black self-tapping lid screws. Molded-in mounting posts accept #2 x 3/16" self-tapping screws for the board; these are not included and are available as 1553WTS100 (pack of 100). The USB connector itself is not included.

The enclosure is designed to meet IP51, carries a UL94-HB flammability rating, and is RoHS and REACH compliant. It ships in a bag at 0.02 lbs (0.01 kg). Some chemicals can damage or weaken ABS, including acetone, thread-locking compounds and cutting or tapping fluids, so check compatibility before use. Factory modification (milling, drilling, printing) is available, and solid models are offered in .stp or .x_t.
