symbol indicates caution due to special circumstances in which hazards may occur.

Warning Failure to follow instructions may result in serious injury or death.

Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss. (e.g., nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc.)
Failure to follow this instruction may result in personal injury, economic loss or fire.
Do not use the unit in the place where flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact or salinity may be present.

Check ‘Connections’ before wiring.
Failure to follow this instruction may result in electric shock or fire.

Caution Failure to follow instructions may result in injury or product damage.

Use the unit within the rated specifications.
Failure to follow this instruction may result in fire or product damage.
Use a dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in electric shock or fire.
Do not use a load over the range of rated relay specification.
Failure to follow this instruction may result in insulation failure, contact melt, contact failure, relay broken, or fire

Cautions during Use

Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected accidents.
When connecting an inductive load such as DC relay or solenoid valve to the output, remove surge by using diodes or varactors.
Use the product after 0.5 sec of the power input.
When using a separate power supply for the sensor and load, supply power to the sensor first.
12-24 VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.
Wire as short as possible and keep it away from high voltage lines or power lines to prevent surge and inductive noise.
When using switching mode power supply (SMPS), ground F.G. terminal and connect a condenser between 0V and F.G. terminal to remove noise.
When using a sensor with a noise-generating equipment (e.g., switching regulator, inverter, and servo motor), ground F.G. terminal of the equipment.
This unit may be used in the following environments.
– Indoors (in the environment condition rated in ‘Specifications’)
– Altitude max. 2,000 m
– Pollution degree 2
– Installation category II

Cautions during Installation

Be sure to install this product by following the usage environment, location, and specified ratings. Consider the listed conditions below.
– Installation environment and background (reflected light)
– Sensing distance and sensing target
– Direction of target’s movement
– Feature data
When installing multiple sensors closely, it may result in malfunction due to mutual interference.
Mount the brackets correctly to prevent the twisting of the sensor’s optical axis.
Retroreflective: If the sensing target has a glossy surface or high reflection, tilt the sensing target with an angle from 30 to 45 degrees and install the sensor.

Use this product after the test. Check whether the indicator works appropriately for the positions of the detectable object.

Through-beam	Retroreflective	Reflective

Emitter – Receiver:
Install to face each other| Sensor – Reflector:
At least 0.1 m apart, install to face each other (parallel with the sensing side of the unit)| Sensor – Sensing target:
Install to face each other (parallel with the sensing
side of the unit)

Cautions for Wiring

Use the round wire with the size of Ø 6 to 10 mm like [Fig. 1].
When extending the wire, use a wire of AWG 20 or higher. (extension length:≤ 100 m)
Use the wire holder, washer, and waterproof rubber together like [Fig. 2].
Select the round wire with the size of Ø 6 to 10 mm for the waterproof and tighten the cable holder by a torque of 1.0 to 1.5 N m.
Be sure to mount the protective cover. Failure to follow this instruction may result in electric shock. Tighten the screw of protective cover by a torque of 0.3 to 0.5 N m.
Use the UL approved stripped crimp terminal that satisfies the size of [Fig. 3].
Tighten the terminal screw with a torque of 0.8 N m.

OCP (over current protection), SCP (short circuit protection)
If short-circuit the control output terminal or supply current over the rated specification, normal control signal is not output due to the protection circuit.

Operation Timing Chart

Light ON mode

Autonics BX Series Universal AC or DC Photoelectric Sensors - fig
7

For preventing the malfunction, the control output maintains off state for 0.5 sec after power-on.
Timer mode: Timer OFF (SW1: ON, SW2: ON)
In Dark ON mode, the waveforms are reversed.

Sensitivity Adjustment

Set the adjuster for stable Light ON area, minimizing the effect of the installation environment.
Use the offered adjustment screwdriver. Do NOT turn with excessive force to prevent product damage.
The steps below are based on Light ON mode.

STEP	Status	Description
01	Received

| Turn the adjuster from MIN to MAX sensitivity and check the position (A) where the operation indicator activates under the light ON area.
02| Interrupted|

| Turn the adjuster from (A) to MAX and check the position (B) where the operation indicator activates under the light OFF area.
If the operation indicator does NOT activate at the MAX (maximum sensitivity): MAX = (B).
03| –| | Set the adjuster at the mid position between (A) and (B) for optimal sensitivity.
