*1. The minimum value when using the solid-state control output on the Amplifier Unit.

Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing distance.

*2. Refer to 6 for cable lengths when combining Amplifier Units and Sensors. The characteristic impedance of the high-frequency coaxial cable is 50 Ù.
