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

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 ... Read More
 
What a Drag!

What a Drag!

CO2 powered drag strip teaches students the science of speed. John Harpell’s 9th grade class at Moira Secondary School in Belleville, Ontario, Canada has built and automated a model racecar track for CO2 powered “dragsters” using various components from AutomationDirect. A CO2 powered dragster is a small lightweight vehicle fitted with a CO2 cartridge; think “pine-wood-derby on ... Read More

Understanding Encoders | White Paper

Encoders are used to determine the position, velocity and direction of a motor shaft or other mechanical motion. They provide information required for the precise control of a variety of applications, such as positioning a rotary table, pick and place, machine assembly, packaging, robotics and more. Regardless of type, all encoders provide a method of orientation detection that’s used as ...

Encoders Explained

Encoders Explained

What are encoders? An encoder (for industrial controls) is a special sensor that captures position information and relays that data to other devices. The position information can be read in many ways (optically, magnetically, capacitively, etc.). There are two basic geometries for encoders: linear and rotary. A linear encoder typically consists of a scale (a ... Read More
