The H25 is the flagship of the BEI Sensors product line. It was designed from the ground up for the industrial marketplace. The H25 offers features such as EMI shielding, high precision ball bearings and matched thermal coefficients on critical components. The encoder meets up to IP66 sealing requirements when ordered with the shaft seal.
Applications:
Machine control; from wood harvesting all the way to processed lumber; oil well logging; agricultural equipment; web process control; food processing.
Model:
H253N-SB-2000-ABZ-15V/OCR-EM14-S
