Part description
No. Name Function1
(1) Digital display (Red) Displays measured values and settings.
(2) PRO indicator (Yellow) Lit when PRO mode is set.

Emitted beam spot check method

  • The emitted beam spot check mode is available to facilitate the confirmation of the laser beam spot position. When this mode is used, the beam spot becomes brighter and flashes.
    Activate the emitted beam spot check mode by following the procedure described below and adjust the workpiece position.

(1) After turning ON the power, make sure that the display shows the following measurement screen. Then, press and hold the UP key for 3 seconds or longer.
The emitted beam spot check mode will be activated.

Emitted beam spot check method (1)

(2) The product emits a spot beam in 1-second intervals.
While observing the beam spot, move the sensor unit and adjust the optical axis.

Emitted beam spot check method (2)
When the "emitted beam spot check mode" is used, sensing objects cannot be measured.
By holding down the UP key for 3 seconds or longer while the "emitted beam spot check mode" is selected, you can return to the measurement display.
The display automatically returns to the measurement display when 2 minutes elapse after the sensor is set to the "emitted beam spot check mode". To continue to adjust the beam axis, hold down the UP key for 3 seconds or longer again to set the "emitted beam spot check mode".


  • When mounting the sensor unit, use M3 screws with washers (length: 25 mm 0.984 in or longer) (not included with the product).
    The tightening torque should not exceed 0.5 N∙m.

When using multiple sensors, mount them so that emitted laser beams do not directly enter the beam receiving parts of other sensors in order to avoid mutual interference. Also, mount them so that spot beams irradiated on a workpiece do not overlap with those of other sensors.
Do not mount the sensors closely side by side to prevent heat generation. Otherwise, the product temperature may exceed the specified temperature due to heat generation.
To prevent the product from falling due to loose screws, take prevention measures such as using screws with washers depending on the operating environment.

  • Use the tightening torque of 0.5 N∙m or less when using the simple mounting bracket MS-HG-01 (optional).

Power supply

  • Verify that the supply voltage fluctuations are within the rating when using the product. Note that applying a voltage greater than the rated voltage or directly applying AC power will result in damage or burning.
  • To ensure performance, use the product at least 30 minutes (warm-up time) after the power is turned 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.
    1) The power supply unit must be certified for use in your region
    2) The output holding time of the power supply unit must be 20 ms or more
    3) The rated output voltage and ripple (P-P) of the power supply unit must be 24 V DC ±10% and 10% or lower, respectively.
    4) The power supply unit with SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low Voltage) that comply with the EMC Directive must be used (if the CE marking compliance is required).
    5) The power supply unit with SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low Voltage) that comply with the EMC Regulations must be used (if the UKCA marking compliance is required).
    6) The power supply unit must support Class 2 (if cTÜVus marking compliance is required).
  • If surges occur, take countermeasures such as connecting a surge absorber to the source of the surges.
  • Do not turn OFF the power while conducting teaching or saving settings such as the PRO mode setting. Doing so can damage the internal memory of the product and may disable the product from restarting.


  • Before wiring work, always turn the power OFF.
  • Do not wire in parallel with a high-voltage line or power line, or run through the same conduit. Doing so may result in malfunctioning due to induction.
  • Apply a load so that a current of 50 mA or more does not flow through the control output line. Also avoid incorrect wiring such as polarity connection error of the power supply. Failure to do so may cause damage or burning.
  • The overall length of the cable can be extended to 10 m 32.808 ft maximum with a cable size of 0.3 mm2 or more. Use a shielded cable to extend the analog wire line.
  • Do not apply stress such as excessive bending or pulling to the extracted part of a cable.

Operating environment

  • This product is suitable for indoor use only.
  • Do not install the sensor in the following locations.
    Locations subject to flammable gas, corrosive gas, or excessive dust
    Locations subject to dust, metal particles, or saline matter
    Atmospheres containing benzine, paint thinner, alcohol, or other organic solvents or strong alkaline substances such as ammonia or caustic soda
    Locations subject to severe vibration or shock
    Locations subject to direct sunlight
    Locations subject to water, oil, or chemicals
    Locations where load is applied to the sensor
  • Avoid using this product in environments where condensation occurs due to sudden temperature change.
  • Performance may not be satisfactory in a strong electromagnetic field.
  • Although it depends on the product type, lights from rapid start type or high frequency lighting type fluorescent lamps, sunlight, etc. may affect the sensing performance. Do not allow those lights to directly enter the emitting / receiving surfaces of the product.
  • Keep the light emitting and receiving windows of this product clean and free of water, oil, fingerprints, and other substances that refract light as well as dust, grit, and other objects that intercept light. When cleaning the surfaces, wipe them with a lint-free soft cloth or lens cleaning paper.
  • Make sure to turn OFF the power supply before cleaning the light emitting and receiving windows of this product.
  • This product is a precision device. Do not drop or otherwise subject to shock. Doing so may cause product failure.
  • Due to the detection principle, if there is a background object in a specific region, a distance different from the actual distance may be displayed. Confirm actual operations in an actual operating environment.

    If an object exists in a particular zone, shield the laser within 24 m 78.740 ft.


  • This product has been developed / produced for industrial use only.
  • Do not use this product outside the scope of the specifications.
    Doing so may result in accidents or failures. It will also significantly shorten the service life.
  • There is a certain deviation in the directivity of this product. When using this product, install the product using a mounting bracket or similar fitting to allow the adjustment of beam axis.
  • The internal memory (non-volatile memory) of this product has a service life. Settings cannot be configured more than one million times.
  • Due to leak light around the detection point, the measurement values may be affected if there exist objects with high reflectance around the detecting point.
  • If specular reflection light enters the beam receiving part, proper measurement may not be possible. When the reflectance of a detection object is high, be careful in installation.
  • When this product becomes unusable or unnecessary, dispose of the product properly as industrial waste in accordance with the applicable law in the country.
