Hammond RL6035BK 147x64x40mm Black Deep Lid ABS Project Box

The RL6035BK is a black deep-lid ABS project enclosure from the RL Series, designed to house PC boards for handheld use. At 147 x 64 x 40 mm in the series ordering table, it is the longer of the two 64 mm-wide sizes; it shares its maximum board size with RL6015 but adds length inside the case. Electronics designers, OEM engineers and integrators use it for handheld instruments, remotes and keypad-driven devices.

It is molded in general purpose ABS plastic carrying a UL94 HB flammability rating. Construction is a two-part, snap action clam shell, and both halves include a smooth recessed area for membranes, keypads or labels. PC board standoffs are molded into both the top and bottom half, and the enclosure is designed to meet IP54.

The part page gives a nominal size of 5.67 in x 2.56 in x 1.57 in (144 mm x 65 mm x 40 mm), while the drawing shows 147.00 mm [5.79 in] x 64.00 mm [2.52 in] x 40.00 mm [1.57 in] overall, with inside dimensions of 140.51 mm [5.53 in] long, 57.51 mm [2.26 in] wide and 34.00 mm [1.34 in] high. Maximum PC board size is 99.81 x 56.81 mm, and shipping weight is 0.21 lbs (0.10 kg).

Each RL6035BK includes the box, lid, four M3 lid screws and four short M3 PC board screws; all bosses accept M3 self-tapping screws and the recommended torque is (43-50) Ozf.in / (30-35) cN.m. For replacements order SC617-50 (M3 x 25 mm lid screws, 50 pkg) or SC622-50 (M3 x 6 mm PCB screws, 50 pkg). It is RoHS and REACH compliant; the light grey version is RL6035.

Hammond can factory modify these enclosures (milling, drilling, printing) and offers solid models in .stp or .x_t. Avoid acetone, thread-locking compounds, cutting fluid and strong solvents, which can damage or weaken ABS.
