In addition, we regularly design and manufacture custom encoders for user-specific requirements. Tese range from ig-volume, low-cost, limited-performance commercial applications to encoders for military, aerospace and similar ig-performance, ig-reliability conditions. We would welcome te opportunity to elp you wit your encoder needs. WARRANTY offers a limited warranty against defects in material and workmansip for a period of one year from te date of sipment.
