1555F Series IP67 Sealed Enclosures


1555F Enclosures from Hammond Manufacturing feature moulded recesses for membrane keyboards


The 1555F series from Hammond Manufacturing is a family of rugged IP67 sealed enclosures designed for wall mounting PCB-based or DIN rail based equipment such as security components, control equipment, and radio repeaters used in harsh industrial environments or outdoor applications. Available in RAL 7035 light gray and moulded in either general purpose ABS or flameproof polycarbonate, these units have a number of innovative features that provide excellent functionality. In use, the lid is secured to the wall or other surface using the slots moulded into the integral flanges. The screws securing the lid to the base are then inaccessible, as they are against the surface, providing security against unauthorized tampering. For maximum security, the units can be attached to the wall with tamper-resistant screws. Standoffs are moulded into both the lid and the base, and, with the exception of the two smallest sizes, DIN rail mounting tabs are also provided. The bottom of the base features a moulded recess for a membrane keyboard or label.

Six sizes range from 4.7”x 2.60"x 1.65” (120 x 66 x 42mm) to 6.30"x 3.60" x2.44” (159 x 91 x 62mm); all lids are fitted with captive M4 stainless steel screws that engage with stainless steel inserts in the base, allowing repetitive assembly and disassembly. Environmental sealing is achieved through a tongue and groove design and moulded silicon rubber gasket; all fixings are outside the gasket seal.
