Hammond Electronics 1555F rugged IP67 sealed enclosure range

Click2Contact

The 1555F range from Hammond Electronics 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 grey and moulded in either general-purpose ABS or flameproof polycarbonate, the units have a number of features that provide good 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, giving security against unauthorised 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, apart from in 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.

The initial six sizes range from 120 x 66 x 42 mm to 159 x 91 x 62 mm; 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 a moulded silicon rubber gasket; all fixings are outside the gasket seal.

All units can be supplied factory modified with machining and silk screening to the user’s specification; AutoCAD and PDF dimensioned drawings can be downloaded from www.hammondmfg.com/1555F_SL.htm.
