MOUNTING DIRECTIONS

Non-shiny Targets
Make sure the sensing side of the sensor is parallel with the
surface of the target object. Do not tilt the sensor towards the
target object.

Sensing side

Surface of target object

Shiny Targets
If the target object has a glossy surface, incline the sensor by 5#

to 10# as shown below, provided that the sensor is not influenced

by any background objects.

Glossy object

If there is a mirror--like object below the sensor, the sensor may

not be in stable operation. Tilt the sensor or keep the sensor far
enough away from the mirror--like object to avoid interfering
reflections as shown below.

ADJUSTMENTS

If the sensor is not in stable operation due to color differences, make a fine adjustment of the threshold level and confirm that the sensor

operates in stable state. Refer to Manual Teaching (Fine Distance Setting.

Adjustment Steps

Install, wire, and turn on the sensor.

Perform distance setting (teaching). Refer to Distance Setting (Teaching) below.

Make a fine adjustment of the threshold, if necessary.

Refer to Manual Teaching (Fine Distance Setting)

Check that the mode selector is set to RUN.

The ON range can be shifted using the UP/DOWN selector and
SET button. The differential travel is fixed.

Precautions

DESIGNING

High-voltage Lines

Do not place sensor power supply or signal lines within the same

conduit as high-voltage power lines.

Voltage Ratings

Do not exceed rated supply voltage, ripple percent (for DC
models), or load current limits.

Ambient Lighting

Do not install the sensor in direct sunlight or other sources of
strong ambient light.

Environmental Conditions

Do not install the sensor in areas

With high humidity, or where condensation would result

With corrosive gas.

With high vibration or shock.

Power Supply

If a switching power supply is used, or when using an inverter or

servomotor, you must ground the FG (frame ground) and G
(ground) terminals on the power supply for proper operation and
to avoid damaging the sensor.

Water Exposure

Although conforming to IP67, do not use the sensor where it may
be immsersed, is outdoors, or is exposed to rain.
To ensure the water resistance of the sensor, tighten the screws
of the operation panel cover to a torque of 0.2 to 0.3 N S m.

Cable

The bending radius of the cable should be at least 25 mm.

When using extended power and signal cable, total length
must not exceed 100 m, with a minimum wire size of
0.3 mm

(22 AWG).

Do not apply tensile force exceeding 50 N to cable (pre-
leaded and connector models).

Avoiding Malfunctions

If using the photoelectric sensor with an inverter or servomotor,
be sure to ground the FG (frame ground) and G (ground)
terminals, otherwise the sensor may malfunction.

Proper Mounting Screws

Use M3 screws and washers to mount the sensor and bracket.

Mechanical Shock

Avoid mechanical shock during installation which may amage the
housing (see Shock specifications)

Short--circuit Protection

If the load short--circuits, the output will be turned off. Disconnect
power and check the wiring. After correcting the shorted
condition, turn power back on. The sensor will reset the
short-circuit protection function. The short-circuit protection is

activated when the current flow is at least 2.4 times the rated
load current. When using an inductive load, the inrush current
must not exceed this factor.

Connector

When connecting or disconnecting the connector, hold the
connector cover to avoid tension on the housoing.

Tighten the connector by hand only. Do not use tools which
may damage the connector.

Always disconnect power before connecting or disconnecting
the connector.

Be sure that the connector is tightened securely. The sesnor
enclosure rating may be reduced or the connector may get
loosened.

MAINTENANCE AND INSPECTION

Cleaning

Solvents damage the casing of the sensor. Do not use
solvents to clean the sensor.

EEPROM Writing Error

If a teaching data error occurs with the operation indicator
flashing due to a power failure or static noise, perform the
teaching operation of the sensor again.
