RT9101
Celesco’s 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.

potentiometer cycle life
is defined as the minimum number of times the sensor can be cycled back and forth, from beginning to
end, before any measureable degradation of the output signal occurs.
