Overview Industry/Application Specifications Related Info  

Overview / Design Principle:

An unbreakable code disk meets the demands of the most severe shock and vibration generating processes. Use of long life 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.

Resolutions from 1 to 600 pulses per revolution; quadrature coding; and differential line driver outputs lets the Series H42 fit well into a wide range of unidirectional and bidirectional applications.

Series H42 encoder is a direct, modernized replacement for the popular Series 42 heavy duty encoders. Use of latest technology optical emitters and sensors, surface mount assembly and precisely fabricated metal components, delivers high reliability and performance in a compact and economical package.
