Resolution is measured in cycles per revolution. Each cycle can provide 1, 2 or 4 counts depending on how many signal edges the quadrature encoder counts. For example, 1000 CPR can provide 1000, 2000 or 4000 counts or pulses per revolution. For 1″ diameter disks, we can provide 32 CPR to 1250 CPR using either the EM1 or HEDS modules. For 2″ diameter disks, we can provide 64 CPR to 2500 CPR using the EM1 or HEDS modules. For linear strips we can provide 120 CPI to 500 CPI using the EM1 or HEDS modules.
