Industrial Encoders

A shaft encoder (also called rotary encoder) is a device that's both electrical and mechanical in design.  Its function is to convert angular motion of a shaft or axle to a digital or analog code.  These are used to monitor either the position of the shaft or to gather data about the shaft's motion to process along with data about speed, position and distance.  Encoders can be used in various applications such as industrial controls, computer input devices, robotics, etc. 

Though there are several types of encoders available, industrial encoders are the most commonly used.  These are almost as tough as heavy duty encoders, and can take abuse in harsh environments that have dust, moisture, particulates, and extreme temperatures.  Options include optical or magnetic engines, absolute or incremental type, solid shaft or hollow shaft (variety of sizes available), and resolutions up to 10,000 PPR. Design options are also available, such as dual row bearings for shock/vibration resistance, bearing-less movement, barrier-free housing, unbreakable code disks for some optical versions, and shaft seals for contaminant protection.  Dynapar brand encoders can be designed to your specification based on the application.  These enhance accuracy in a demanding environment.
