Custom Electronics Housings Available

The custom electronics housing for our Hawk instrument enclosures provides a reliable and extremely accurate method for mounting your electronics. Hawk explosion-proof instrument enclosures feature four internal cast rails with drilled and tapped holes which are specially designed for the EC1896 plastic electronics housing insert. The insert will house an LCD and a printed circuit board and can be rotated to one of four 90 degree positions. It is specially designed so that the display will get as close to the glass as possible, thus providing an optimal viewing angle.

This electronics housing insert also fits into the Plastic Hawk instrument enclosure, which means that you can market to both hazardous and safe areas with the same product design.
