Product Description
The HD25 is a rugged optical incremental shaft encoder designed for heavy-duty industrial applications. The housing, machined from a solid billet aluminum block and finished with clear anodizing, conforms to the industrial standard size 25 package. Size 25 encoders are widely used and are considered to be the backbone of feedback devices found in factory automation and industrial applications. The HD25 will drop directly into existing applications to provide a superior solution at a competitive cost. The HD25 is a factory stock product with little or no lead-time.
Typical applications include:
- Automation, robotics, motion control, elevator controls, machine tools, food processing, X-Y tables and conveyors.
- Lathes, grinders, CNC machine tools, high performance servos, test equipment, packaging machines, balance machines and cutting machines.
- Web processing, rotary tables, transfer machines, stacker cranes, press controls, printing presses and pump controls.
- Oil field equipment, saw mill machinery and construction machinery.
Our absolute encoders may be used in many stand alone applications that do not require a PC interface. For these applications we provide detailed communications protocols for all of our absolute products (see the SEI Absolute Encoder Communications Protocol page).
