*1 Semi-open collector (Open collector + Pull-up) is our proprietary output circuit, which allows direct connection even if the pull-up voltage at the signal receiving end is higher than the sensor power supply voltage.
Unlike a simple open collector, it provides pulse output with a voltage close to the sensor power supply voltage.
*2 Differential (balanced) CMOS logic can be used as an unbalanced signal. When using as a balanced signal, please check the power supply voltage and output voltage specifications.
*3 The output voltage of the GP type is theoretically proportional to the speed, but the GP type prevents unnecessary increases in output to improve reliability.
