| *1 This is the value when considering linearity + hysterisis + repeatability in a stable environment of 23°C. *2 The repeatability, based on consistent conditions, is the difference in the detection points at the time of fluctuations in the repetition. *3 When the temperature of the piping exceeds 80°C, do not connect the cable. *4 Consumption current including output is 0.6 A and under. *5 The maximum load resistance R will be the values below in response to the electric voltage E. When 10-23V: R = ?38 x (E-10) + 128? ? When 23-30V: R = 622 ? |
