HEDS-9140#A00
Product Description
Product Overview
The HEDS-9040 and HEDS-9140 series are three-channel optical incremental encoder modules designed for precise rotary position detection when used with a codewheel. These low-cost modules offer high performance with a highly collimated light source and a unique photodetector array. They provide two-channel quadrature outputs with an index pulse, enabling sophisticated motion control. Ideal for high-volume applications such as printers, plotters, tape drives, and industrial automation equipment, these encoders deliver reliable performance in demanding environments.
Product Attributes
- Brand: Avago Technologies
- Product Type: Optical Incremental Encoder Modules
- ESD Warning: Normal handling precautions should be taken to avoid static discharge.
- Note: Avago Technologies encoders are not recommended for use in safety critical applications.
