Cases provide strength and light weight

Val-An 900 series 19-inch rack-mount cases are constructed from strong, lightweight composite materials such as glass fiber. Seamless composite shells provide water-tight protection, structural stability, and resistance to harsh environmental factors and corrosion. The cases are de-signed to be used independently or stacked, allowing users to set up a "cabinet type" system in the field. Each case is molded with an integrated pattern that interlocks when cases are stacked. Stacking latches can be employed as well. Front and rear case access is standard through removable covers with a choice of latch options, making installation of rack-mounted equipment quick and easy.Zero Corp.For more information, call 1-800-828-6344 x011 and enter the product code.

Enclosure offers testing capability

The Table Top high-performance, portable, shielded enclosure is designed for fast, convenient EMI/RFI testing in a table-top, rack-mounted, or in-line format. The enclosure meets EMI/RFI shielding requirements of 120 dB+ and is suited for wireless, cellular, PCS radio, cordless, and pager applications. It is available in four standard space-saving sizes ranging from 18 × 18 to 36 × 36 inches, as well as a 12 × 12-inch version. The Table Top enclosure fulfills requirements for EMI/RFI, EMS, EMC, cell-to-cell, electronic board, RF resistor, two-way radio, and susceptibility testing. It is also suited for equipment isolation or burst electronics applications.

Boxes provide electrical insulation

HE Series Himeline small electronic enclosures are made of lightweight, durable thermoplastic polycarbonate. The insulated boxes comprise a lid and case. Opaque lids and bases are made of PVC; transparent lids are polycarbonate. Each enclosure features self-extinguishing double insulation, and sealing gaskets. HEH K1 and HEH K2 kits easily convert the screw cover to an internal hinge. Optional internal/external hinges are also available. HE Series units attach directly or with wall brackets, and all models except hinged boxes meet IP-55 standards. Applications include instrumentation and electronic communications.

Enclosures accommodate smaller, more powerful electronics

Slim Line 2000 industrial machine control enclosures provide NEMA 12/IP65 protection while eliminating excess heat. The lightweight extruded-aluminum enclosures offer a rear door option and custom sizing for both height and width. In addition, front panels can be either flush mounted or recessed. The enclosures feature versatile external mounting on all sides using the extrusion T-slot, which offers the added benefit of concealed hardware. Models are available with extremely flat profile depths of 90 and 120 mm and mounting depths of 65 and 95 mm. When used with a suspension arm system, the enclosures can be freely suspended or mounted as a standing unit. Rose+Bopla Enclosures

Housing combines modern appearance and versatility

The JP injection-molded plastic housing features a "Euro-style" design that is a sleek alternative to standard housing designs. The snap-in header gives designers a tamper-proof environment for completed electronic components. A recessed-top version of the housing features a curb that protects switches or indicators such as LEDs. A flat-top version is also available. JP housings feature matching 8- and 11-pin octal-style headers. Both headers come with standard hollow pins or with JIT's Double Thru pin arrangement, which eliminates pigtail wiring in the manufacturing process.

Unit eliminates separate cooling

PSK climate-controlled enclosures can save time and money by eliminating the process of cutting out air conditioner mounting holes and fastening the air conditioner to the enclosure. The pre-assembled enclosure is equipped with a specially designed solid front that also acts as the enclosure door, concealing the cooling device. The cooling unit ensures that the interior temperature of the enclosure will be maintained at a constant level. An internal thermostat is used to set the required internal temperature of the enclosure in the range of 68 to 131F. The cooling unit can be quickly and easily removed and re-installed for easy servicing. Rittal Corporation
