Hammond PJHMI66CCH 6x6 Clear Polycarbonate HMI Cover, Screw Closure

The PJHMI66CCH is a 6x6 hinged HMI cover kit with a clear polycarbonate cover held closed by screws. It mounts over a cutout in an enclosure wall to protect instruments or electronics that need routine attention, while the clear cover keeps displays and indicators in view. Controls engineers and panel builders use it where an operator must see a device without opening the enclosure.

The frame (WGF66) and clear cover are injected polycarbonate; the cover pivots on a 316 stainless steel hinge pin (70-HPIN6316) and seals on a formed-in-place (FIP) polyurethane gasket in a continuous channel. The cover closes with two NEMA cover mount 316 screws with O-rings that thread into #10-32 threaded inserts. The series offers the clear polycarbonate thermoplastic cover version as PJHMI66CCH; the matching opaque cover version is PJHMI66H. It is UV stabilized for outdoor use and rated for a service temperature of -31°F (-35°C) to 266°F (130°C).

The frame measures 5.93 in (151 mm) H x 6.15 in (156 mm) W x 2.27 in (58 mm) D, with a viewing area of 4.47 in (114 mm) H x 4.69 in (119 mm) W; the nominal size is 6 in x 6 in x 2 in (152 mm x 152 mm x 51 mm). Installation needs a Phillips screwdriver or similar tool: mark and cut a panel opening of up to 4.47 in H x 4.69 in W, drill 7/32 or #2 (.220 dia) holes, and mount the kit with 8 fasteners. The supplied hardware suits mounting surfaces from .059 in to .250 in thick (the series is designed for wall thicknesses from 16 gauge through 1/4 in), torqued to 15-20 in-lbs. An optional prop arm, PJHMIPROP66, is available separately.

The PJHMI66CCH is a listed UL component (UL File E487574) for use with enclosures rated Types 1, 3, 3R, 4, 4X, 12 or 13, and is CSA listed Type 1, 3, 3R, 4, 4X, 12 or 13. It is REACH and RoHS compliant and ships at 1.5 lbs (0.68 kg).
