Hammond RL6165BK 105x65x30mm Black ABS Project Enclosure, IP54

The RL6165BK is a slim 105 x 65 mm ABS plastic project enclosure from the RL Series of shallow-lid boxes, designed to house P.C. boards for hand-held use or wall mount. It suits OEM engineers, electronics builders and integrators who need a black housing for a small circuit board assembly. On the 105 mm x 65 mm footprint it is the low-profile 30 mm option; RL6175 shares the footprint at 40 mm tall.

The enclosure is molded in black general purpose ABS plastic with a light texture and uses two-part construction. Both the box and the shallow lid carry a smooth recessed area for a membrane, label or silkscreen, and P.C. board standoffs are molded into both halves, with bosses that accept M2.6 self-tapping screws.

Nominal size is 4.13 in x 2.56 in x 1.18 in (105 mm x 65 mm x 30 mm), with inside dimensions of 100.25 mm [3.95 in] long, 59.72 mm [2.35 in] wide and 24.70 mm [.97 in] high. It accepts a maximum P.C. board of 99.43 mm x 59.43 mm. This is the version without wall mounting flanges; the flanged equivalent is RL6165-FBK. Shipping weight is 0.14 lbs (0.06 kg).

Each purchased assembly includes the box, lid, 4 PCB screws and 4 lid screws, and the recommended screw torque is (43-50) Ozf.in / (30-35) cN.m. The RL6165BK is designed to meet IP54, uses UL94 HB rated ABS, and is RoHS and REACH compliant. Some chemicals can damage or weaken the plastic, including acetone, ketones, thread-locking compounds, cutting or tapping fluid and strong solvents, so use only plastic-safe cleaners. The enclosure can also be factory modified (milling, drilling, printing), and solid models are available in .stp or .x_t. The light gray counterpart of this size is RL6165.
