Hammond RZ0304 115x65x40 mm Beige ABS Watertight IP65 Enclosure

The RZ0304 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.

This is the low-profile 40 mm deep version of the 115 x 65 mm footprint, with 35.00 mm of inside height for flat boards up to 106.87 x 56.87 mm. Overall size is 4.53 in x 2.56 in x 1.57 in (115 mm x 65 mm x 40 mm); the drawing gives an inside height of 35.00 mm [1.38 in] and an inside width of 58.22 mm [2.29 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 RZ0304GASKET (2-pack).
