Gurley LP20 Series Modular Incremental Encoders Motion Type: Rotary Usage Grade: Medical/Non-MIL Low Dose Radiation Applications Output: Incremental Max Resolution: Disc Dependent High Performance / Low Profile The Gurley LP20 series modular encoders represent a versatile range of rotary incremental encoders. Its modular construction provides friction-free operation and the wide selection of disc sizes affords the design engineer great flexibility. Features/benefits include: - low profile read head design provides high performance where space is limited - vacuum compatibility for semiconductor and aerospace applications - data (A-quad-B), index and commutation tracks available - minimal adjustment required by customer during installation - radiation tolerant version optional (call factory for more information) There are presently two standard systems available, each with A-quad-B, index and two commutations tracks (shown with redundant reads heads; single head versions available) - 80mm OD x 30mm ID with 2,048 lines or 8,192 counts after quadrature - 158mm OD x 103mm ID with 8,192 lines or 32,768 counts after quadrature Gurley Precision Instruments 514 Fulton Street Troy, NY 12180 U.S.A.
