EPS, an Elma Company, offers shielded
cabinets that have been tested to MIL-STD-461D specifications for EMC. Based on
Optima's M-series, the shielded cabinets feature a rugged steel or aluminum
frame. EMC features include shielded door handles, wrap-foam gasketing
around the door with conductive adhesives, EMI filters, copper gasket fingers
and steel-mesh gasket strips. All of Optima's M-series cabinets also
feature reinforced corner members, cross-bracing and stiffeners to handle
rugged applications. The M-series has also passed MIL-STD-901D and MIL-STD-810F
for shock and vibration.
Optima can also provide creative EMC
solutions for advanced shielding requirements. Incorporating tin-plating
or other conductive metal surfaces with superior electrical continuity
properties can help reduce offending radiated emissions. Using
cost-effective materials, a minimum electric field attenuation of 60 DB of
shielding effectiveness from 100 KHZ to 1 GHZ decreasing to a minimum of 46 DB
at 10 GHZ can be achieved.
A range of
accessories, colors and custom options are available for Optima's cabinets. The
company also offers transit rack cases, command consoles and desks for rugged
California’s plan to mandate an electric vehicle market isn’t the first such undertaking and certainly won’t be the last. But as the Golden State ratchets up for its next big step toward zero-emission vehicle status in 2018, it might be wise to consider a bit of history.
A customer who was thermal printing strip steel had a problem: When the strip's speed increased, the thermo printer would catch fire. When he set a flame to a piece of the strip, he couldn't get it to burn. What was the problem?
