Series H56 Rotopulser© Heavy Duty Encoders
- The most rugged and reliable pulse generator available
- Suitable for severe duty in paper, steel, and lumber mills
- Large outer bearings isolate internal encoder from excessive shaft loads
Overview / Design Principle:
The H56 Rotopulser® design employs an “encoder within an encoder” construction. The internal, high performance hollowshaft encoder is isolated from severe application environments. The heavy duty, cast aluminum housing features two heavy duty bearings and a 5/8″ diameter shaft that is available with an optional drive shaft. The housing is completely sealed for washdown and temperature rated for outdoor use.
Complete electrical protection guards against failure due to overvoltage, reverse voltage, and output short circuits. For downtime critical applications, a second, redundant output can be ordered to allow quick changeover. The optional dual isolated outputs are completely independent, so one pulse generator can be used to provide drive feedback while the other provides input to a process controller or PLC.
Features and Benefits:
The Series H56 Rotopulser® heavy duty encoders electronics offer the greatest flexibility and reliability. It operates from 5 to 26 VDC power and provides wide voltage, line driver outputs that are compatible with all common motor drives, PLCs, and process controllers. Additionally, the outputs are protected from overvoltage or reverse voltage input power, and the outputs are protected against short circuits.
The Series H56 Rotopulser® encoder is tested to meet the stringent noise immunity requirements of the Electromagnetic Compatibility Directive of the European Union, EN50082-2. Stable performance is guaranteed, even in the presence of high current switchgear, radio transmitters, and noisy equipment.
