s SLITS FOR THROUGH-BEAM SENSORS
E39-S46 Slit Set
Using slits allows smaller objects to be detected and reduces
the sensing distance.
Slit width Sensing distance
0.5 mm
1 mm
2 mm
0.5 m (1.64 ft)
1.1 m (3.61 ft)
2.4 m (8.20 ft)
Min. object size
0.5 mm (0.02 in)
1 mm (0.04 in)
2 mm (0.08 in)
Use the rubber attachment with the metal cover if a slit width of
2 mm is required. Insert the 0.5- or 1-mm slit between the metal
cover and rubber attachment if a slit width of 0.5 or 1 mm is
desired. These slits fit into the rubber attachment.
NOTE: Apply the slit to the lens of the photoelectric sensor
marked with an arrow indicating the position of the
optical axis (apply it to the bottom lens of horizontal
sensors and the top lens of vertical sensors).

s OPTICAL AXIS CONFIRMATION REFLECTOR E39-R5
Use this attachment when the set distance is long and
adjustment is mechanically difficult with a sensing object.
Attach the reflector to the receiver (refer to the figure).
Look at the reflector from right behind the emitter. The
Eye
reflector should be bright with red light when the optical
beam strikes the reflector. If the emitter has a turbo
function, the reflector looks brighter with the function
switched on.
When the reflector is removed, the light beam strikes the
receiver.

s ADJUSTER CAP AND OPTIONAL E39-G2 SENSITIVITY ADJUSTER KNOB
Adjuster Cap (Supplied with each sensor)
In order to prevent the sensitivity or OFF-delay time that
has been set from changing accidentally, cover the
adjusters with the adjuster cap (enclosed).

E39-G2 Adjuster Knob
To temporarily use the knob to adjust the sensitivity of the
photoelectric sensor, insert side A into the shaft of the
sensitivity adjuster. To snap the adjuster onto the sensor,
push side B onto the sensitivity knob.
(A)
Press the adjuster cap until
this face touches the name
plate on the sensor.

s E39-E6 MUTUAL INTERFERENCE FILTER
A set of 4 filters are sold together for two through-beam
models (for 2 each of emitters and receivers).
The arrow printed on the cover indicates the direction of
polarization. By attaching the filters opposite to each other
in polarization to the emitters and the receivers (refer to
the figure) in rows, mutual interference can be prevented
(in any case, the filter attached to an emitter and to the
corresponding receiver must be the same in direction of
polarization or the photoelectric sensor will not function).

Be aware of the direction of
