Hammond RM2055L Deep 190x140x71 mm ABS Instrument Enclosure

The RM2055L is the deepest 190 x 140 mm RM Series enclosure at 71 mm, a light grey ABS instrument case for large P.C. boards with tall parts, stacked boards or internal wiring that needs room. It is designed to house P.C. boards for instrument use and suits OEM engineers, designers and electronics builders.

The enclosure is molded in light grey general purpose ABS plastic with a light texture, while the front and rear panels are smooth. The material carries a UL94 HB flammability rating. It uses two-part clam shell construction, and the front and rear panels are interchangeable and easily removable for modification. The drawing shows screw-accepting P.C. board mounting points on both the inside bottom and inside top.

Listed dimensions are 190 mm long x 140 mm wide x 71 mm deep, and the RM2055L accepts a P.C. board of up to 180.2 x 127.5 mm. Inside height is 64.50 mm [2.54 in]. Shipping weight is 0.71 lbs (0.32 kg).

Tongue and groove construction provides protection against dust and water, and the design is intended to meet IP43. The halves are secured with M3 Phillips machine screws threaded into integral brass bushings, which suits applications where the case is opened and closed repeatedly; the drawing lists the M3 x 40mm lid screw as replacement pack SC613-50. Each purchased assembly includes the box, lid, 2 end panels, 4 P.C. board screws and 4 lid screws; recommended torque is (43-50) ozf.in / (30-35) cN.m. The optional FT-01 folding foot kit mounts to the bottom half toward the front to angle the front panel for viewing.

The RM2055L is REACH and RoHS compliant. Enclosures can be factory modified (milling, drilling, printing) and solid models are available in .stp or .x_t format.
