Encoders, Hollow Shaft
1.45" Diameter Optical Encoder with IP66 Sealing
Quantum Devices Inc. has developed a sealed housing for their QD145 line of encoders. The housing boasts a split clamshell like design that allows for easy access to shaft mounting. Dual O-rings seal the encoder inside the housing, and seal the housing against the encoder mounting surface. Standard 30 degree rotary adjustment is still provided along a 1.812 Bolt Circle Mount.
Outputs consist of quadrature with reference pulse and three-phase commutation, which can be configured with either the industrial standard 5 volt RS422A Line Driver or the 5 to 26 volt OL7272 line driver. A flexible member allows for much greater tail shaft run out than can be tolerated by modular encoder designs plus 30 degrees of rotation for commutation timing. A housing constructed of conductive carbon fiber composite provides the EMI shielding of an all metal housing and performance of a lightweight robust assembly.
