Sensing Method

Notes for Operation

・Prevent incidence of reflected light from the floor or wall.

・Do not expose the photoelectric switch to sunlight or other direct light projections.

・Do not strike the photoelectric switch with a hammer when instlalling, otherwise the waterproof

characteristics will be impaired. (Except for UL / c-UL)

・For preventing the transient state when turning power on, a circuit to turn output off (universal

voltage: 200 ms, DC power: 50 ms) is contained. On the timer-function model, time-delay

operation starts when the output is released from the off state. Take care of the operation when

turning power on.

・Do not use the photoelectric switch under conditions exceeding the rated operating

temperature, vibration resistance, and shock resistance.

・Use the photoelectric switch within the rated power voltage.

・When using a switching power supply, connect the FG (frame ground) terminal to a proper

ground.

・When compliance with the EU Low Voltage Directive is required, connect an EN approved fuse

outside the power terminals of the universal voltage type.

・Install the cover maintain the water-proof characteristics, install the cover in a regulated

position.

Wiring Diagram

①Connect wires starting from the lower terminals.

②Install the cover using the captire screw.

Use a cable of 8 to 10 mm in diameter to ensure water- and dust-proof characteristics(Except

for UL / c-UL). Two gland packings are supplied; for cables of 8 to 9 mm and 9 to 10 mm in

diameter. Use a proper gland packing and a gland washer, and tighten the gland firmly. Keep

the cable insulation within 5 mm from the gland packing as shown above. Make sure that the

gland washer is placed in the gland packing correctly.

・Turn off the power supply before wiring.

・Connect correctly to prevent damage.

・The power voltage must not exceed the rated range.

・The cable should not be run in the same wire duct with other power supply, motor, or

electromagnetic lines because induction noise will cause malfunction or damage to the

photoelectric switch.

・Cable extension is allowed up to 100m using a cabtyre cable with core wires of 0.3 mm

more. On the DC power supply type, consider the voltage drop by the resistance of the cable.

Optical Axis Alignment & Sensitivity Adjustment

(1) Through Beam Type

Direct the projector and the receiver face by eye measure and fasten them tentatively. Direct

the receiver upward, downward, and sideways and lock the projector in the middle where the

indicator on the receiver goes on.

(2) Polarized retro-reflective

Direct the sensor upward, downward, and sideways and lock the reflector in the middle

where the indicator goes on or off.

(3) Diffuse-reflective

Place the sensing object and direct the sensor upward, downward, and sideways and lock

the reflector in the middle where the indicator goes on or off. Without the sensing objects in

place, check the indicator goes off. If the background influences, make the sensitivity

adjustment as follows.

(a) With the sensing object in place, turn the sencitivity adjusting control clock wise from MIN

position until the indicator goes on (point A).

(b) Remove the object, then the indicator will go off. Turn the sensitivity adjusting control further

clockwise until the indicator goes on again by detecting the background (Point B).

gives the best sensitivity.

NOTE: Use the attached screwdriver to make adjustments. Avoid excessive force to the

sensitivity adjusting control to prevent damage.

(4) Make the sensitivity adjustment of the background suppression (BGS) as follows.

(At dark on operation, read lighting the operation indicator in a different way as turning off

and adjust it.)

①First, direct the sensor and place the object, turn the sensitivity adjusting control

counterclockwise until the indicator goes off. Then turn the sensitivity adjusting control

clockwise until the indicator goes on (Point A).

②Remove the object, then the indicator will go off. Turn the sensitivity asjusting control further

clockwise until the indicator goes on again by detecting the background (Point B) (*1).

③Set the sensitivity adjusting control at Point C, the middle point between A and B (*2).

*1: Make one turn or more clockwise from point A and set the position as point C when the

background is too far and the operation LED dose turn on.

*2: There may be more than 1 turn between points points A and B, since this photelectric

switch incorporates a 6-turn adjuster.
