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
F2LP-W-50M, F2LP-W75M, F2LP-W100M: Electrostatic capacity 100 nF/km; characteristic
impedance 50 2

Sensitivity selector
Timer mode selector
(see note 1)
POWER indicator:
Lit when power is on.
OPERATION indicator:
Lit when sensing objects.
Frequency selector:
If induction or other mutual inter-
ference is experienced when us-
ing more than one Sensor, set the
Sensor to different frequencies.
Sensor selector:
F2LP-W10M, F2LP-W20M: Select dia.
of 10 to 20
F2LP-W50M, F2LP-W75M,
F2LP-W100M: Select dia. of 50 to 100
Compensation selector: Select the
position according to the cable length.
When cutting or extending the cable,
the length should be between 1.5 m
and 10 m.

Note: 1. Timer mode selector: NORM:
No timer; TIMER: OFF-delay
transistor output (40 ms)
2. Output mode selector:
NO: Both transistor output and
relay output ON when sensing
objects; NC: Transistor output
OFF and relay output ON
when sensing objects

Note: 1. Relay outputs are ON when ob-
jects are sensed (when objects
pass through the Sensor head)
2. Each relay output is ON for 40
ms minimum regardless of the
position of the timer mode se-
lector.
