Note: 1. The moving speed is based on the natural fall of objects from a height 10 cm above the Sensor.
2. The cable can be shortened or connected to another cable, as long as the total length of the cable is from 1.5 to 10 m. Use the following cables for extension: F2LP-W10M, F2LP-W20M: Electrostatic capacity 97 nF/km; characteristic impedance 50 2 τ F2LP-W-50M, F2LP-W75M, F2LP-W100M: Electrostatic capacity 100 nF/km; characteristic impedance 50 2 τ
