Functions & Features
• Providing a DC output proportional to a potentiometer or
slidewire position input
• Constant voltage excitation allows use with pots with total
resistances from 100 Ω – 10 kΩ without affecting accuracy
• 50 % zero/span adjustments with minimal interaction
• High-density mounting
