Why Choose Medium-Voltage Drives?
Energy savings and other benefits of more common, low-voltage ac drives are becoming well known. Medium-voltage drives, operating from higher electric supply, bring ‘heavy lifting’ capability and... » more
Dual voltage SCR dc motor speed control, up to 2 hp motors
The OMDC-250 Series variable speed dc control offers flexibility, reliability, and value, according to Omega Engineering. The general purpose control is rated and tested to 2 horsepower. » more
Dustproof, flood-tight proximity switches
Proximity sensors: Dustproof and flood-tight proximity switches offer industry-compatible mounting capability with IP52-IP68 (~NEMA 2-6) enclosure ratings. » more
ABB displays military robotic automation concepts, capabilities
Military Vehicle Exhibition, Aug. 11-12 in Detroit, MI, look at ways to apply industrial robotic technology to automate military supply chain, logistics and field operations. » more
Integrating safety in automation requires specialized knowledge
In a typical automation project, maximum efficiency is key. However, undertaking a safety automation project presents additional challenges. First, legal requirements must be met. Second, care must... » more
