RT9101
Celesco鈥檚 model RT9101 provides a voltage
feedback signal for rotational position. The
sensing element of this device is a precision
plastic-hybrid potentiometer which provied
superb linearity and resolution.
This innovative sensor from Celesco,
desinged to meet tough NEMA-4 and IP67
environmental standards, is available in full-
stroke measurement ranges of 1/4 to 50 turns.
Because the sensor is potentiometric, the
RT9101 is absolute and will maintain position
information even after a loss of power.
