Autonics BJX Series Rectangular Photoelectric Sensors

Product Information
The Transparent Guide Rectangular Photoelectric Sensors BJX Series is a product used for sensing applications. The product is available in three sensing types: Through-beam, Polarized retroreflective, and Diffuse reflective. The product has a stable and an unstable light on/off area, and it operates on a 10-30 VDC power supply. The product comes with a reflector, MS- 2A, and Bracket A or B (depending on the cable or connector type). The product is sold separately, and the ordering information is provided in the manual.

Do not disassemble or modify the unit.
Do not connect, repair, or inspect the unit while connected to a power source.
Check connections before wiring.

Cautions

Use the unit within the rated specifications.
Use a dry cloth to clean the unit and do not use water or organic solvent.

Cautions during Use:

Follow the installation instructions for Through-beam,Retroreflective, and Reflective types.

Setting Operation Mode:

Set the operation mode to L (Light ON) or D (Dark ON) mode.
For detailed information on product components, ordering information, and connections, refer to the instruction manual.

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.
Failure to follow this instruction may result in explosion or fire.
Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire.
Do not connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in fire.
Check ‘Connections’ before wiring.
Failure to follow this instruction may result in 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 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 varistors.
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.
10-30 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 3
- 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.
For installation, tighten the screw with a torque of 0.5 N m. Mount the brackets correctly to prevent the twisting of the sensor’s optical axis.
Do not impact with a hard object or bend the cable excessively. That could decrease the product’s water resistance.
Use this product after the test. Check whether the indicator works appropriately for the positions of the detectable object

Setting Operation Mode

Be sure to set the mode before power-on.
Use the offered adjustment screwdriver. Do NOT turn with excessive force to prevent product damage.

Operation Timing Chart

Light ON mode

Autonics BJX Series Rectangular Photoelectric Sensors-
fig5

In Dark ON mode, the waveforms are reversed.
Operation indicator and transistor output differ from the sensing method.

Connections

Circuit

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

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.
