FHx58 rotary encoders are the most robust rotary encoders in the MEGATRON encoder program.
The mechanical/housing design of the FHx58 encoders is optimized for:
Quick and easy cleaning with water or steam with or without chemical additives
Applications with high hygiene requirements (e.g. medicine-, food- applications)
Coastal regions near the sea, or at sea
Withstand of high radial and axial shaft loads
The FHI58 series complements the magnetic high-performance absolute rotary encoders HTB58 and HTS58 with an optical
rotary encoder in identical quality. An integrated electronic warning system (EWS), which can be ordered as an option, mon-
itors the optical system of the encoder. An error status signal is output if the expected lifetime of the optical system is less
then 1000 operating hours.
A very large selection of optical coding discs oers a wide range of resolutions and rounds o the positive overall picture.
