Nemaco™ - NEMA 12 Enclosures, Powder Coated, 1/4 Turn Latches Rating: Dust Proof & Water Resistant, Nemaco Technology, LLC

Welcome to Nemaco Technology's reference section that provides technical information for type of NEMA 12 enclosure. Nemaco has dedicated a technical section for NEMA 12 enclosures. This technical reference section provides the basic NEMA enclosure rating & definition, common sheet metal materials, mechanical hardware, paint coatings, environmental seals, miscellaneous parts and electrical accessories (if applicable). And Nemaco has provided a typical NEMA 12 enclosure examples (shown in the photos) for our customers. The top photo shows a NEMA 12 enclosure with the front door and two quarter turn latches available from Nemaco. The next photo (below) shows the door open with continuous seals inside the enclosure door. The front edges of the NEMA 12 enclosures required good seal to keep out dust and to be water resistance (to dripping water from a pipe, if applicable). Nemaco uses proven enclosure designs that eliminate most of the office dust and factory dust from getting on electronics. Also, Nemaco fabricates most NEMA 12 enclosures from carbon steel materials (i.e., sheet metal, hinges) and then powder coats entire enclosure surfaces uniformly. After the power coating is cured and dry, then Nemaco will get the other remaining parts (foam seals, handles, latches, etc.) assembled and completed for a quality NEMA 12 enclosure. By the way, Nemaco can offer customers a spectrum of powder coat & paint colors including the super Tigerbox™ orange. And after the NEMA 12 enclosure is completed and packaged properly, then Nemaco will have the enclosure shipped per the customer's preferred freight company.

Nemaco has prepared the next sections as samples of Nema 12 enclosures used in industry and therefore, a customer should have a better understanding of the common enclosure applications and the associated NEMA ratings and definitions. Also, whenever possible, Nemaco will provide additional (Nemaco type enclosure & Tigerbox enclosure) photos with external and internal images of the other Nema 12 enclosure. You can call Nemaco for additional information if needed so you can find the correct enclosure for your industrial, commercial or military application.

Indoor NEMA 12 Enclosure Lab Application: A typical NEMA 12 enclosure would be a metal box used for electrical controls in a lab or any indoor environment that is dry but might have dripping pipes but no rain. Usually, this type of NEMA 12 enclosure has medium manufacturing cost due to the materials and power coating. Most NEMA 12 enclosures have a foam gasket or seal on the door or any covers to prevent dust from gettting inside. Note that NEMA 12 enclosures should have a inner drip shield for most applications.

Indoor NEMA 12 Enclosure Computer Enclosure in Factory Application: Most modern factories have computer controls and electric systems for automation. The NEMA 12 enclosure keeps the dust out of the electrics and the PLC'S (programmable logic controllers) for the factory automation systems. Also, Nemaco can provide air conditioning units to keep the electronics cool inside the NEMA 12 enclosure. By the way, sometimes vortex coolers can be installed on this dust proof NEMA 12 enclosures. Also, note that factories have alot of dust and many pipes, therefore a NEMA 4 or NEMA 12 enclosure is a good solution to keeping a factory running and profitable.

Call or send Nemaco if you have any questions about your particular NEMA 12 enclosure, cabinet or box application.
