The RZ0308 is a water-tight enclosure from the RZ Series, built from beige ABS plastic with a smooth-surface opaque lid and designed to meet IP65. It is aimed at OEM engineers, electronics designers and panel builders who need to house a printed circuit board or DIN rail mounted components in an indoor setting.
It shares the 115 x 65 mm footprint of the 40 mm deep size but stands 55 mm deep, giving 49.50 mm of inside height for boards with taller components, up to 106.87 x 56.87 mm. Overall size is 4.53 in x 2.56 in x 2.17 in (115 mm x 65 mm x 55 mm); the drawing gives an inside height of 49.50 mm [1.95 in] and an inside width of 57.72 mm [2.27 in].
The lid uses a gasketed, two-piece tongue and groove construction that protects against the entry of oil, dust and water. Lid screws are self-captivating: the lid holes are threaded the first time the screws are installed. For wall mounting, the through box-blind hole construction places the mounting holes outside the gasket perimeter, so fixing the box to a wall does not breach the seal.
The purchased assembly includes the box, lid, string gasket, 4 PCB screws and 4 lid screws; PCB bosses accept M3 self-tapping screws and the recommended lid screw torque is 43-50 ozf.in (30-35 cN.m). The ABS material carries a UL94 HB flame rating with a temperature range of -30 °C to +80 °C, and the part is RoHS and REACH compliant. Replacement gaskets are sold as RZ0308GASKET (2-pack).

It is IP65 rated. The RZ Series is designed to meet IP65, with a gasketed two-piece tongue and groove lid that protects against oil, dust and water.
The maximum P.C. board size is 106.87 mm x 56.87 mm. The drawing shows an inside height of 49.50 mm [1.95 in] and inside width of 57.72 mm [2.27 in]; PCB bosses accept M3 self-tapping screws.
The RZ Series literature suggests the ABS material for indoor use, rated -30 °C to +80 °C. For outdoor use it suggests polycarbonate; the gray polycarbonate equivalents of this size are RZ0205 and RZ0205C.
This part is 55 mm deep with 49.50 mm inside height. The ordering table lists RZ0304 as the 115 x 65 x 40 mm Beige ABS size; both accept the same 106.87 x 56.87 mm maximum PCB.
No. The chemical resistance statement advises against Red Loctite or any thread locking compound on this ABS enclosure, along with acetone, ketones, strong solvents and cutting or tapping fluid.
The replacement gasket for this size is RZ0308GASKET, supplied as a 2-pack string gasket.
