Note:
1. Response frequencies are minimum values applicable to DC solid-state control output used to measure standard sensing objects,
each separated from one another with a distance that is double the side dimension of the sensing object and located at a distance
that is half the maximum sensing distance.
2. The cable length varies with the Amplifier Unit and Sensor Head in combination. Refer to the table on the next page. The character-
istic impedance of the coaxial cable is 50
Ω
