M1000 Datasheet, PDF (4/6 Pages) GSI Group, Inc. – Mercury TM1000 Analog Output Encoder Systems For Customer Interpolation- Resolution to 0.078μm

System Specifications
System
Grating Period 20µm
Signal Period 20µm
System Resolution Fundamental resolution: Linear 20µm; Rotary 2500 - 16,384 CPR
Interpolated resolution determined by customer electronics:
Linear: 20µm - 0.078µm; rotary: 2,500 to 4.2M CPR
Linear Accuracy* Better than ±1µm available; contact MicroE
Better than ±3µm up to 130mm, ±5µm from 155mm to 1m,
±5µm per meter from 1m to 2m
*Maximum peak to peak error over the specified movement when compared to a NIST-traceable laser interferometer
standard, used at room temperature and with MicroE interpolation electronics.
Rotary Accuracy* Scale O.D.
