H40 SHOCK PROOF OPTICAL ENCODER
Extra Heavy Duty Encoder
Product Description
The H40 is an ultra heavy duty encoder whose internal structure is totally isolated from severe shock and shaft loading conditions. The optics and
electronics are supported in shock absorbing material within the heavy cast outer housing. The encoder shaft is flexibly coupled to the high load
capacity bearings and shaft assembly, which is carried in the outer housing. The entire bearing assembly is field-removable to permit proper shaft
support while pressing pulleys, gears, etc. onto the shaft. An Underwriters Laboratories listed version of this model is available.
