Incremental rotary encoder 835H series

opticalhollow-shaftrugged

The series 835H is a range of hollow-shaft optical encoders designed for applications that require precise motion sensing. The series offers three models with the same mechanical and electrical specifications such as LED illumination which provides reliability, push-pull photo-transistors designed to give good signal stability, and internal flexible coupling to provide easier installation. The units can fit any shaft size that reaches up to 30 mm in diameter. The shaft has a simple yet robust design with no threads, shoulders, or other length requirements. It also has ABEC class 7 bearings which protect it against contaminants. The Series 835H Hollow-Shaft Optical Encoders are rugged, high-performance devices designed for use where precise motion sensing is critical. The Series 835H is available in three different models. They have the same mechanical and electrical features, but differ in performance and price. The following features are common to all models: !! Optional zero index! Fits any size shaft up to 1.2”(30mm) diameter ! Simpler design of user’s shaft: No threads, shoulders, or critical length requirements! Internal flexible coupling for easier installation! Combination synchro/face mount or square-flange mount! Shielded ABEC Class 7 bearings for protection against contaminants! Precise chrome-on-glass discThree Models available: single reading head; resolution up to 8 times the line count on the disc. two reading heads for higher accuracy; resolution up to 80 times the line count on the disc. four reading heads for the highest accuracy; resolution up to 80 times the line count
