Overview Industry/Application Specifications Related Info  

Overview / Design Principle:

Encoder models with resolutions of 1024 or less are equipped with an unbreakable code disk that meets the demands of the most severe shock and vibration generating processes. Long life, heavy-duty bearings keep tough loads from disrupting internal alignment, avoiding failure due to the disk "crashes" so typical in competitive encoders. Protection against installation problems such as wiring errors prevents the encoder from damage, while immunity to electrical noise keeps the encoder signals intact. An IP66 / NEMA4 sealing option protects against damage from contamination.

Packaged in the European standard 58mm enclosure, the Series H58 offers a variety of mechanical options: servo or face mounting on 42mm or 48mm bolt circles, 6mm or 10mm shafts, and an optional 36mm pilot. Electrical options include: resolutions from 1 to 2540 pulses/revolution; single ended push-pull or differential line driver outputs; and a choice of connector or cable terminations.

The Series H58 encoder utilizes the latest technology optical emitters and sensors, surface mount assembly and precisely fabricated metal components to deliver high reliability and performance in a compact and economical package.
