Specifying and Sizing Motor Starters

There are four basic motor control options available: Basic contactors, traditional starters, manual motor starters, or combination starters. A basic contactor is a special purpose relay that is used to control large electrical currents. Similarly, a traditional starter utilizes overload relays, auxiliary and alarm contacts, and mechanical interlocks to create a reversing unit. On the other…

What Type of Photoelectric Sensor Is Best For Me?

There are many different styles of photoelectric sensors, but really only four basic technologies: through-beam, reflective, diffuse, and background suppression. The chart describes some advantages and disadvantages of each technology. To learn more about AutomationDirect’s photoelectric sensors visits www.AutomationDirect.com/photoelectric.

Choosing The Right Proximity Sensor

Proximity sensors allow non-contact detection of objects. Therefore, they are used in many industries, including manufacturing, robotics, semiconductor, and many more. Inductive sensors detect metallic objects while capacitive sensors detect all other materials. Ultrasonic sensors detect all materials by using sound wave reflections to determine presence. All applications have certain specific needs, but, in general, the…

Thermal Management: Enclosure Cooling Tips

You need to cool down – Heat inside an enclosure can decrease the life expectancy of controlling units such as your PLC, HMI, AC drives and other items. Excessive heat can cause nuisance faults from your electrical and electronic components: for example, overloads tripping unexpectedly. Heat will also change the expected performance of circuit breakers and fuses, which can cause whole…

Selecting an Enclosure Fan or Air Conditioner

Internal and External sources often cause enclosure internal temperatures to rise above the ratings of the control equipment. Internally, the same items that can be damaged by heat (power supplies, PLC systems, AC drives/inverters, HMI systems, battery back-up systems, servos, etc.)  may also be the source of the heat. Externally, sources of heat that can

Selecting an Enclosure Heat Exchanger

Heat inside an enclosure can decrease the life expectancy of controlling units such as your PLC, HMI, AC drives and other items. Excessive heat can cause nuisance faults from your electrical and electronic components. Heat will also change the expected performance of circuit breakers and fuses, which can cause whole systems to shut down unexpectedly.
