Hammond RP1165 165x85x40mm Watertight ABS Enclosure, Opaque Lid

The RP1165 is a light gray ABS water-tight enclosure with an opaque lid, measuring 6.5 in x 3.35 in x 1.57 in (165 mm x 85 mm x 40 mm). It gives electronics designers, OEM engineers and panel builders a sealed general-purpose housing for printed circuit boards or components.

The body is general purpose ABS plastic with a UL94 HB flame rating. A two-piece tongue and groove lid joint with a rubber gasket (supplied loose for field installation; the drawing specifies an EPDM grey string gasket) protects against the access of oil, dust and water, and the lid carries a smooth recessed area for a membrane, label or silkscreen.

This elongated 165 x 85 mm body is only 40 mm high, taking a PC board up to 157 x 77 mm with 158.75 mm of inside length. The drawing gives overall dimensions of 166.00 mm [6.54 in] long, 86.50 mm [3.41 in] wide and 40.00 mm [1.57 in] high, with inside dimensions of 158.75 mm [6.25 in] long, 78.75 mm [3.10 in] wide and 34.40 mm [1.35 in] high. The series ordering table lists this size as 6.54 in (166 mm) x 3.43 in (87 mm) x 1.57 in (40 mm). Shipping weight is 0.44 lbs (0.20 kg).

Each purchased assembly includes the box, lid, string gasket, four PCB screws and four lid screws. The lid is secured with self-captivating M3.5 stainless steel machine screws threaded into corrosion resistant bushings for repeated assembly and disassembly; recommended torque is 43-50 ozf.in (30-35 cN.m). Internal mounting holes accept M3 self-tapping screws, and optional inner panels are available as STC117 (3 mm black ABS) or STA117 (1 mm metal).

The RP1165 is designed to meet IP65 and is RoHS and REACH compliant. Hammond cautions that acetone, ketones, thread-locking compounds, cutting fluids and strong solvents can damage ABS and polycarbonate enclosures, so check chemical compatibility before use.
