Hammond Brand: Hammond

The Hammond PJ Series of Polyester Junction Boxes are designed for use as instrument enclosures, electric, hydraulic or pneumatic control housings, electrical junction boxes or terminal wiring enclosures.
They provide insulation and watertight protection to IEC 60529, IP66, where equipment may be hosed down or otherwise become very wet.
Ideal for use in applications with high temperatures or highly corrosive environments.

The moulded fibreglass polyester enclosures with matching doors, can be easily punched, cut, or drilled.
They come in a light grey finish and feature enhanced UV inhibitors to protect against outdoor weathering.
The enclosure doors are supported by a continuous stainless steel hinge and are secured with Snap Latch door fasteners, which include provision for the addition of a padlock.
The enclosure doors are fitted with a captive, oil resistant gasket, which provides a seal when the door is closed.
10-32 threaded brass inserts are provided on the inside rear of the enclosures, to enable fitting of an optional internal mounting panel. Mounting hardware is included.
Threaded brass inserts are also provided to the rear of the enclosures for fitting of mounting feet/brackets.
Stainless steel mounting brackets and hardware are included to enable wall-mounting of the enclosures at the rear.


Optional inner panels are available for the range of enclosures, in a white powder coated steel finish.
