HEDR-8000 series

This is the description about HEDR-8000 series of the reflective optical surface mount encoders. The HEDR-8000/8100 Series encoders use reflective technology to sense rotary or linear position. This sensor consists of an LED light source and a photodetector IC in a single SO-8 surface mount package. When used with a reflective codewheel or codestrip, this device can sense rotary or linear position.

Here are the features of HEDR-8000 series: Reflective technology; Surface mount SO-8 Package; Two channel quadrature outputs for direction sensing; Two encoding resolution options: 2.76 2.95 lines/mm (70 75 lines/inch), 5.91 lines/mm (150 lines/inch).

The reflective surface mount optical encoders of HEDR-8000 series provide two square wave outputs in quadrature for count and direction information. These TTL compatible outputs correspond to the alternating reflective/nonreflective pattern of the codewheel or codestrip. The HEDR-8000/8100 series encoders can be used over a range of codewheel and codestrip resolutions. The HEDR-8000/ 8100 reflective encoder can operate from 2.76 to 2.95 lines per mm (70 to 75 lines per inch). The HEDR-8100 can be used with a codewheel or codestrip with 150 lines per inch (5.91 lines per mm).

These are notes of HEDR-8000 series. Avago technologies encoders are not recommended for use in safety critical applications. Eg. ABS braking systems, power steering, life support systems and critical care medical equipment. Please contact sales representative if more clarification is needed.
