The EX550-AL-W Dual Hawk dual-compartment explosion-proof instrument enclosure has a window front cover for the electronics compartment and a solid back cover for the connections compartment. It is made of aluminum, and it comes with one top and two side conduit connections of 3/4", and one bottom process connection of 1". The electronics compartment includes four internal cast rails with drilled and tapped holes that make it easy to mount electronics up against the window. The base of this compartment also includes four drilled and tapped holes to mount additional components. The connections compartment includes four drilled and tapped holes for mounting a PCB or other components. The enclosure has provisions for attaching a tag as well as making the covers tamper-proof. Like all ExDirect aluminum flame-proof instrument housings, the EX550-AL-W family of Dual Hawk enclosures carry UL, CSA, ATEX, and IECEx approvals.
