Product Spotlight: Continuous Hinge Type 12 EMC Junction Boxes

EMI Shielded Junction Boxes

bisco industries is happy to announce that we now carry continuous hinge Type 12 EMC junction boxes from Hoffman. Hoffman’s Type 12 EMC junction boxes are specifically designed for indoor applications to contain electromagnetic interference (EMI) signals. These enclosures not only restrict EMI signals from devices inside but also protect against external EMI and RFI signals. The continuous hinge Type 12 EMC junction boxes are built from mild steel and are categorized as wall mount enclosures.

Enclosure Features

  • 16 or 14 gauge steel construction
  • Seams continuously welded and ground smooth
  • Continuous hinge design
  • Bonding provision on door
  • Combination woven steel mesh and oil-resistant gasket
  • Stainless steel screw-down door clamps
  • Weldnuts provided for mounting optional panels and terminal kits in size 6.00 x 4.00 in. (152 x 102mm) and larger (panels sold seperately)
  • Shielding effectiveness greater than 80 dB at 1 GHz
  • UL Rated

Navigating Global Enclosure Standards

Enclosures protect both devices and people on a daily basis. For example, computer enclosures not only protect computers from outside contaminants like water but also protect people from dangers like electrocution. In more complex applications failure to protect devices or systems with proper enclosures could result in the loss of thousands of dollars or worse yet, worker injury.  In efforts to ensure worker safety and device protection several standards have been developed. The three primary international standards for electrical enclosures are:

Although helpful, these standards tend to be complex and at times downright confusing. To further complicate matters many applications do not even require enclosures to meet a particular industry standard. For those applications the temptation is to find cheaper alternatives without truly understanding the application requirements or considering IEC, NEMA, or UL rated enclosures. However, as a recent whitepaper from Hoffman Enclosures explained, “Focusing solely on low price without fully understanding or requiring industry standards can yield a low initial product cost, but could ultimately lead to high maintenance expenses, component failure and in the worst case, worker safety issues”.
