Three-Channel Encoder Suits Industrial Automation Applications
Providing a resolution of up to 1000 counts per turn, the HEDM-5540 optical transmissive three-channel encoder from Avago Technologies can operate in temperatures from -40°C to 100°C, suitable for use in industrial environments. The TTL-compatible devices accept 5V and provide a third-channel index output in addition to two-channel quadrature, with a 90 electrical degree, high true index pulse output with up to 100 kHz frequency response. A drop-in replacement for the previous series, the 30mm × 41.1mm × 18.3mm encoder is available with external mounting ears and includes features such as a lensed LED source and detector and output circuitry.
