EX-M161H□ / EX-M161L□

Sensing fields

• Horizontal (left and right) direction

When using sensors of the same model side by side, up to two units can be mounted in direct contact. However, interference may occur depending on sensor alignment and background conditions. Verify that there is no interference before use.

• Vertical (up and down) direction

Correlation between lightness and sensing range

The sensing region (typical) is represented by oblique lines in the figure. However, the sensitivity should be set with enough margin because of slight variation in products.
Lightness shown may differ slightly from the actual object condition.
* Sensing object size: 15 mm × 15 mm 0.591 in × 0.591 in.

Correlation between material and sensing range

The bars in the graph indicate the sensing range (typical) for the respective material. However, there is a slight variation in the sensing range depending on the product.
Further, if there is a reflective object (conveyor, etc.) in the background of the sensing object, since it affects the sensing, separate it by more than twice the sensing range shown in the left graph.

• This product has been developed / produced for industrial use only.
• This product is suitable for indoor use only.
• Do not install the product in locations where it may come into contact with organic solvents such as thinner, strong acids, alkalis, chemicals, water, or oils and grease.
• Since this device does not have a protective structure, ensure that liquid does not adhere to the device.

Power supply

• Note that applying a voltage greater than the rated voltage or directly applying AC power will result in damage or burning.
• Do not use during the initial transient time (approx. 50 ms) after the power supply is switched on.
• If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
• Make sure that the power supply input satisfies the following items.
• The power supply unit must be certified for use in your region.
• The output holding time of the power supply unit must be 20 ms or more.
• The power supply unit must have a rated output voltage of 5 V to 24 V DC ±10%, ripple P-P of 10% or less, and a current capacity of 0.5 A or greater.
• If CE marking is required, the Safety Extra Low Voltage (SELV) or Protective Extra Low Voltage (PELV) of the power supply unit must comply with the EMC Directive.
• When using the product as a UL Recognized product, use a UL-certified Class 2 power supply unit.
• If surges occur, take countermeasures such as connecting a surge absorber to the source of the surge occurrence.
• For DC power supply, always use an isolation transformer. If an autotransformer is used, this product or power supply may be damaged.
• To protect the product from abnormal voltages on the power supply line, use an isolated power supply with a built-in protection circuit.
• If using a power supply without a built-in protection circuit, always supply power to the product through a protective element such as a fuse.
• Depending on the duration of a momentary power interruption, the product may either continue operating or return to the same state as when power is first applied. Avoid using the product in environments where momentary power interruptions may occur.

Mounting

• When securing the sensor with screws, use M3 screws and tighten to a torque of 0.49 N·m or less.
  Further, use small, round type plain washers (ø6 mm ø0.236 in).

• Avoid using or storing the product in locations in an environment where dew condensation may occur due to a sudden temperature change.
• Performance may not be satisfactory in a strong electromagnetic field.
• Sensing performance is affected if there is a reflective object (conveyor, etc.) behind the sensing object although it depends on the material. Provide a sufficient distance from the reflective object.
• When using multiple sensors, install so that they do not receive each other’s emitted light directly.
• When using sensors of the same model side by side, up to two units can be mounted in direct contact. However, interference may occur depending on sensor alignment and background conditions. Verify that there is no interference before use.

Wiring

• Before wiring work, always turn the power OFF.
• If equipment that generates electrical noise (such as switching regulators or inverter motors) is installed near the product, connect the equipment’s frame ground (F.G.) terminal to ground.
• Connect the load so that the current flowing through the output line does not exceed 50 mA. Also, avoid incorrect wiring such as reversing the power supply polarity. Failure to do so will cause damage or burning.
• The overall length of the cable can be extended to 50 m 164.042 ft maximum with a cable size of 0.3 mm² or more.
  Check to make sure that the terminal voltage of this device is 4.5 V or more.
• In order to reduce noise, make the wiring as short as possible.
• Do not apply stress such as excessive bending or pulling to the extracted part of a cable.
• Perform installation and cable routing in a room temperature.
  Be careful not to cause excessive stress to cables after they are routed.
• Always insulate the ends of unused cables to prevent contact with other wires.
• Do not run the wires in parallel with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
