Specification No. 02045-001 Rev.08-11

H40 Shock Proof Optical Encoder

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 pul-

leys, gears, etc. onto the shaft. An Underwriters

Laboratories listed version of this model is available.
