Quantum Devices, Inc. Optical Rotary Encoder QR200

Quantum Devices Model QR200 incremental rotary encoder provides an improved rotary encoder feedback solution in applications typically using modular encoders. With an overall length of 0.93" and the stability of a bearing encoder design, model QR200 can provide significant performance upgrades in applications limited by traditional modular encoder solutions. Outputs consist of a quadrature with reference pulse and three-phase commutation, which can be configured with either the industrial standard 5 volt RS-422 Line Driver or the 5 to 26 volt OL7272 line driver. A flexible spring mount allows for much greater tail shaft run out than can be tolerated by modular encoder designs, plus it provides 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 the performance of a lightweight robust assembly. Use QR200 with our QC201 Commutation Indicator for faster, easier motor encoder alignment. QR200 Incremental Rotary Encoder Design Features:500 kHz fundamental frequency response Low profile, 0.93″ assembled height Bearing design simplifies encoder attachment Up to 10,000 lines per revolution, 40,000 post quad4, 6 or 8 pole commutation Conductive carbon fiber housing1.812″, 2.375″ bolt circle or size 21 resolver mounting Through shaft sizes up to 0.625″ diameter High noise construction Note: prior to transitioning to RoHS-compliant, the product name was QD200 rather than QR200. Therefore, when cross-referencing a QD200 configuration, simply substitute the configuration prefix with QR200.
