Laser safety precautions

Use of controls or adjustments, or the performance of procedures other than those specified herein, may result in hazardous radiation exposure. The LV series product uses a laser diode as a light source.
Specifications of the laser diode change depending on the model. Refer to the tables below.
Sensor head Wavelength Maximum output FDA class IEC class LV-H32, H37, H42, H52, H62, H67 H47, H35, H64, H65, H100, Hnm 3 mW II 2 LV-H41, Hnm 2.5 mW I 1

Safety consideration

Follow the safety precautions below to ensure operator safety: Operate the LV Series only according to the procedures described in this instruction manual. Otherwise, injury may occur due to exposure to the laser beam. Do not disassemble the sensor head. Laser emission from the LV Series is not automatically stopped if the sensor head is disassembled. If you disassemble the sensor head for inspection or repair, you may be exposed to the laser beam. If the LV Series malfunctions, contact KEYENCE immediately. Do not look directly at the laser beam. Looking directly at the laser beam may result in serious eye injury. Protective enclosure It is recommended that you install a protective enclosure around the sensor head to prevent any person from getting near the sensor head during operation. Protective goggles It is recommended that you wear protective goggles when using the LV Series. Stop laser emissions before cleaning the laser emission port. Failure to stop the laser emission may expose eyes or skin to the laser beam. Check the laser beam path. To prevent exposure to the laser beam due to specular or diffuse reflection, install a screen which offers the appropriate reflectance and temperature characteristics to interrupt the reflected laser beam. Do not install the LV Series in such a way that the laser beam passes at eye height.

Setting value Time

The setting value is adjusted to the midpoint of the difference in received light intensity when the target is absent and present.
The setting value is displayed.

Reference:

Differentiation Mode Detection (UP/DOWN edge) Detects only sudden changes in received light intensity within a certain time interval. UP edge detection: Output is turned ON when light intensity increases by more than the setting value within a fixed time interval. DOWN edge detection: Output is turned ON when light intensity decreases by more than the setting value within a fixed time interval. To achieve stable detection in differentiation mode, changes in received light intensity resulting from the presence or absence of the target must be greater than the changes in received light intensity resulting from dust or vibration.

The displayed value for excess gain is 0 when the excess gain is less than 1%.

If an error message other than the above is displayed, contact KEYENCE.
Minimum input time is 20 ms.
Caution on usage of QL (LV-20A only)
Mutual Interference Suppression
The LV Series is equipped with a mutual interference suppression function. Please note, however, that this mutual interference suppression function will not work when two main units are used together.
When you want to monitor the received light intensity in a PLC using the KEYENCE QL-R01, note that the indication will be limited in the range of 0 to 4095, and that the threshold value that can be written in LV using the QL-R01 is up to 4095 (common to all of FINE, TURBO and SUPER TURBO). Monitoring of the received light intensity and writing of the threshold value using QL-R01 are possible in the LV-20A only. Up to eight expansion units can be mounted on the QL-R01 provided all the expansion units are the LV-20A. Refer to "Mounting additional amplifier" (page 4) and the instruction manual for the QL-R01. LV requires two QL channels because a single LV unit has two output channels. Restrictions due to compliance with EMC Directive: When linking four LVs or more to the QL-R01, install a ferrite core to the root of the QL-R01 cable.
When additional sensor head units are installed, mutual interference suppression allows the units to be positioned close together. The number of units with which mutual interference suppression will work depends on the selected power mode.

Hints on Correct Use

To extend the ampliffiler cable length, use a cable that has a crossectional area of at last aa 0.3 mm2. Limit the length of cable extensions to 100 m. (For further information on connecting several units contact KEYENCE) Placing the amplifier cable together in the same conduit with power lines or high voltage lines may cause detection errors due to interference or sensor damage. For this reason, always isolate the amplifier cable from these lines. If using a commercial switching regulator, make sure to ground both the frame ground terminal and ground terminal. Do not use the LV Series outdoors, or in any location where extraneous light can directly enter the light receiving surface. At the maximum sensitivity setting, detection distance may vary somewhat due to slight differences in the characteristics of individual units. Improper wiring may cause the amplifier to become hot or alter sensitivity. (Input/Output Circuit Diagram: page 7) Do not use connectors for sensor head-to-amplifier connections more than 100 times. Displayed values may vary due to surrounding conditions (e.g. temperature changes, dust) Cautions on using the LV-H62/H67 Use FINE mode when there are any white or mirror-surfaced objects near the sensor head. When the output is unstable in standard 1 mode (Std), change the detection mode to standard 2 (Std2). Reflector The values on the received light intensity display may vary depending on the surface condition of the reflector.

Wide Area Thrubeam Type LV-H300/H100
KEYENCE CORPORATION, 2003 LV-KA-C-1-0703 Printed in Japan
A thrubeam type has been added to the LV series of general-purpose laser optic sensors.
The bright red laser beam allows you to easily check whether the target is present in the detecting area.
Since the beam can be clearly viewed, the optical axis can be easily aligned.
Reflective Types Also Available!
For mounting in a limited area targeting only small parts.

Detecting distance:

78.74" (2,000 mm)
0.39" (10-mm) and 1.18" (30-mm) types are available.

LV-H300 1.18" 30 mm

Worlds smallest size
The volume is reduced to a quarter of our previous model.

Linear area beam

Even when the detecting distance varies, the beam area width hardly changes.

LV-H100

0.39" 10 mm
Optical axis alignment is easy, and the detecting area can be clearly viewed.
Four strong points for easy operation.
Industry leader in laser sensor development
Both thrubeam and reflective sensor types boast an abundant lineup. The world s largest number of sensor head variations meets the needs of any site.
Applications (also given on the back cover)

Conventional model

The optical system is drastically improved compared with previous products. As a result, a small size suitable for general-purpose sensors has been achieved for the first time ever. The volume is reduced to a quarter* of previous models.

* LV-H300T

Compared by volume to conventional models
Linear area beam (Transmitter)

Industry First

Laser element
A new principle has been developed that uses a prism to provide a sharp linear beam. Wherever a target is passed, you will find that it is easily detected within the sensing area.

(Patent pending)

Prism Reflecting mirror
Detection of loose workpieces
Detection of double-fed workpieces
Detection of the drop of small components
Light diffusion sheet (Receiver)
The mounting bracket (optional) enables the position of the beam to be adjusted.
A light diffusion sheet for beam confirmation is placed at the end of the receiver. Even while the sensor is being operated, you can visually confirm that the receiver receives the area beam.
The position of the beam can be adjusted in both a vertical and horizontal direction.
Loose workpieces are detected using the sensors area beam. Since the beam is visible, setup can be easily performed. By using two outputs, presence/absence of a part can be determined as well as if a workpiece has been double-fed. The EDGE detection mode enables stable detection even in an environment that gradually becomes dirty. In addition, output time can be adjusted using the timer function.
Mounting brackets for both a vertical and horizontal installation are available.
Wide & Linear Area Beam Expands Sensor Applications

Direct access

Setting and fine adjustment of the sensitivity can be performed directly without switching the mode.
Detection of sagging or breakage of wire rod
Differentiation of workpiece length

Bar LED indicator

The bar LED indicator shows the sensors operation status.

One-touch connection

The cable length can be adjusted using the dedicated connector.
The linear area beam allows you to visually check whether the wire rod is present within the detecting area.
Differences in the screw length are differentiated based on the difference in the interrupted light intensity. Using two outputs enables you to detect the presence/absence of screws, in addition to differentiation of the length.
Detection of small components
Differentiation of workpiece thickness
Two-stage digital display
The current and preset values are shown on the upper and lower displays. The sensor can be adjusted just like a counter.
New Amplifier LV-51M Ideal for Laser Thrubeam Sensors
Thrubeam type amplifier units LV-51M/52
Setting of reference light intensity This function allows you to select and set the light intensity to be displayed. For example, the light intensity can be displayed according to the detection width of the sensor head.

Area detection

With the definite detection area, the LVH47 can ignore any influence of background conditions.
The width of the detecting area can be changed with the slit.
Model: LV-L02 (Optional accessory) The LV-H47 can ignore variations in target shape and position in the direction of the laser line.
The LV-H35 enables highly accurate detection regardless of the installation conditions.
