• Resolution after quadrature: 5 and 1 micron
• Output Format: Differential RS422 line driver output. Two count channels A and B in quadrature with an optional ZR output
• Quadrature spec.: 90° ± 45° at maximum conditions
• Rise and Fall Time: 1 µs max., with 1000 pF load
• Travel length: up to 250mm (special lengths available on request)
