Autonics BYS500-TDT Photoelectric Sensors with Synchronous Detection

Product Information

• The BY Series Photoelectric Sensors with Synchronous Detection are designed for use in various industries, including nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc. They have a fail-safe device that must be installed when using the unit with machinery that may cause serious injury or substantial economic loss.
• The sensors should not be used in places where flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact, or salinity may be present. The unit should not be disassembled or modified. Connections should be checked before wiring. The unit should be used within the rated specifications and cleaned with a dry cloth only.
• The BY Series Photoelectric Sensors come in different models and combinations. The specified model can be selected from the Autonic website. The product components include an emitter, receiver, circuit, load, operation indicator, and bracket.
• The product dimensions vary for front and side detection types. The sensors operate on a power supply of 12-24 VDC and have a sensing distance of up to 150 g. They have a response time of 940 nm and operate in Dark ON mode. The sensors have an operation indicator (red) for indicating the operational status.
• The sensors have various approvals and certifications, including OCP, SCP, NPN circuit, insulation resistance, noise immunity, dielectric strength, vibration resistance, and shock resistance. They are protected against residual voltage and have a protection rating for use in different environments.

• the symbol indicates caution due to special circumstances in which hazards may occur.
  Warning Failure to follow instructions may result in serious injury or death.

1. A 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.

2. 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 an explosion or fire.

3. Do not disassemble or modify the unit.
   Failure to follow this instruction may result in fire.

4. Do not connect, repair, or inspect the unit while connected to a power source.
   Failure to follow this instruction may result in fire.

5. 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.

1. Use the unit within the rated specifications.
   Failure to follow this instruction may result in fire or product damage.

2. 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 a 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.

• 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 the switching mode power supply (SMPS), ground the F.G. terminal and connect a condenser between 0V and F.G. terminal to remove noise.

• When using a sensor with 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
  • The 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 0.3 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.

Connections

• Be sure to use the same power for the emitter and receiver.
• Be sure to connect the synchronous wire (white) of the emitter and receiver.

Circuit

NPN open collector output

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