Main circuit of Sensor Connections Note: Shielding Conductor Terminal 7 (internal circuit 0 V) can be grounded by grounding the Sensor, because this terminal is connected to the metal case of the Sensor. Sensor input terminals 7 and 8, transistor output terminals 10 and 11, power supply terminals 1, 2, and 3, and relay connecting terminals 4, 5, and 6 are insulated from one another. 100 VAC 200 VAC, 50/60 Hz Precautions Please read the following carefully to ensure effective and proper use of the F2LP-W.

To mount the F2LP-W75M on a flange, open a hole of at least 112 dia. min. Others Do not use the Sensor immediately after power is on, since the Metal Sensor needs an interval of 1 to 2 seconds after power is on to function normally and sense objects. To maintain noise resistance when connecting a Sensor cable to the Amplifier Unit terminals, always use a cable with a conductor thickness of no more than 10 mm. 10 mm max. Note: F2LP-W100M 150 dia. min. Metal Metal Note: 25 mm To mount the F2LP-W100M on a flange, open a hole of at least 150 dia. Sensor Metal Sensor cable Amplifier Unit Only one pulse (40 ms) will be output when the sensing object is stationary or if the sensing object is always present such as the case when line breakage is detected. When using the Sensor at a high level of sensitivity, be careful not to touch or come in contact with the Sensor because any contact with the sensing surface will be detected.
