The ELESTA GmbH develops and produces a modular, 3-channel, miniature optical encoder system which may be of special interest for you as a manufacturer of complete rotary encoders. This system is characterized by an extremely small installation volume and a very low power consumption of 4 - 6 mA.
This encoder system consists of a sensor with connector cable and a code wheel. It can be easily integrated and the print design as well as the pin assignments can be customized.
MAIN FEATURES - Incremental optical encoder
- Unique code wheel design
- High precision reflective system
- Low current consumption
- Easy assembly
- Very compact mounting form
- High immunity to positional tolerance
