Basic Information
User-friendly, high precision laser sensing!
UL/C-UL,CE,FDA,UKCA Approved
UL/C-UL : Recognition (Excluding LS-403)
FDA : LS-H□F□ only
Features
We offer 6 types of laser sensor heads for various applications
Industry standard mounting pitch
The mounting pitch for sensor heads is 25.4 mm 1.000 in, the same industry standard as the CX-400 series Ver.2 general purpose photoelectric sensors. Hence, existing mounting brackets can be used even when replacing general purpose sensors with laser sensors.
Easy and accurate adjustments
[Long sensing range spot reflective type] [Long sensing range line reflective type]
A spot-size adjuster is built into the back of the sensor head allowing the user to adjust the sensor easily while viewing the spot. The adjuster is adjustable with a screwdriver to avoid accidents during maintenance or any other time the sensors are handled.
Line-up of FDA / IEC / JIS Class 1 type [LS-H91(F)-A, LS-H21(F)-A]
Visible light spot using the Class 1 type. This makes beam axis alignment much easier.
![Line-up of FDA / IEC / JIS Class 1 type [LS-H91(F)-A, LS-H21(F)-A]](https://tp.industry.panasonic.com/hubfs/pid-corp/products/fasys/sensor/photoelectric/ls/images/pic12.jpg)
Sensor mounting bracket for beam axis alignment is available [MS-CX-11]
It is possible to make a minor adjustment for the bracket by 4 degrees up, down, right or left, even after setting up the sensor. The bracket can be mounted in both longitudinal and lateral directions.
Easy setting, dual display
Equipped with 2 large 4-digit digital displays. While checking the current incident light intensity (red display), the optimal threshold value (green display) can be set easily.
2 switches enable simple operation
Only two switches, the large MODE key and the large jog switch, are required for operation.
Wiring and space saving
The quick-connection cables enable reductions in wiring.
(connector type)
The quick-connection cables enable reductions in wiring. (connector type)
The connections and man-hours for the relay terminal setup can be reduced and valuable space is saved. Also, LS-400 series amplifiers can of course be connected side-by-side with a connector type amplifier of FX-500/FX-300 series digital fiber sensors or DPS-400 series digital pressure sensors.
Note :Because the transmission method varies depending on the amplifiers, check the instruction manual for the amplifiers when connecting them.
New release of type with upper communication functions to facilitate preventive maintenance!
[LS-403]
Network communication possible
Can connect to Open Network CC-Link IE Field / CC-Link / DeviceNet / EtherCAT via Communication Unit for Open Network SC-GU3 series. Monitoring and various settings can be done from PLC, PC, etc.
*CC-Link and CC-Link IE Field are a registered trademark of Mitsubishi Electric Corporation.
DeviceNet is a registered trademark of ODVA (Open DeviceNet Vender Association, Inc.).
EtherCAT is a registered trademark of Beckhoff Automation GmbH.
*Refer to SC-GU3 series.
Threshold tracking function saves maintenance time
This function seeks changes in the light emitting amount resulting from changes in the environment over long periods (such as dust levels), so that the incident light intensity can be checked at desired intervals and the threshold values can be reset automatically. This helps to reduce the man-hours for maintenance.
Accurately sense the minutest variations (M.G.S. function)
When sensing at close range or when the target objects are transparent or minute, adjust the sensor receiving sensitivity to one of 3 levels (U-LG mode: 4 levels) for the optimal setting. In addition, changing the receiving sensitivity will not effect the response time.
4 new modes enabling wide array of sensing
[Hysteresis mode]
By adjusting the hysteresis, convexo-concave parts of uneven objects can be cancelled enabling more stable sensing.
[Window comparator mode]
The sensor judges any object outside the range of incident light intensity established by two set threshold values.
[2 independent output modes]
By combining two outputs, a wide array of control is possible, allowing you to detect meandering objects, for example.
[Differential sensing mode] Only rapid changes in light received are detected, which enable the edge of glass, etc. to be detected accurately. Optimal for positioning.
MODE NAVI customized function
Frequently used functions such as response time, M.G.S. function, data bank load, emission halt function and D-CODE values can be stored in CUSTOM mode. The settings can also be changed easily.
Emission halt function
If you do not want to place a laser spot in the visual range of the image processor, you can stop the laser radiation using the emission halt signal from the external input.
Cable type allows external input
The LS-401-C2 cable-type amplifier is equipped with an external input wire (5-core). It is ideal to use the laser sensor at places where external teaching or laser light emission halting is to be carried out, or at places where the laser sensor is to be used separately.
Interference prevention function
The automatic interference prevention function prevents against interference among up to 4 sensors.
Setting conditions viewed at a glance (D-CODE)
The amplifier setting is shown in an 8-digit code. This is handy for remote indications and follow-ups.

Applications
Detecting objects with a complex shape
Its linear sensing area enables more stable detection of objects with complex shapes.
Detecting the remaining amount of sheet rolls
The coaxial retroreflective sensor with a spot diameter of approx. ø1 mm ø0.039 in (at a 1 m 3.281 ft sensing distance) can measure amounts remaining on sheet rolls with high precision.
Detecting electronic component pins
Because its spot shape can be adjusted in accordance with the object, it can be easily set to detect even the minutest object from a remote location.

②Press down the rear part of the mounting section of the unit on the 35 mm 1.378 in width DIN rail and fit the front part of the mounting section to the DIN rail.
<How to remove the amplifier>
①Push the amplifier forward.
②Lift up the front part of the amplifier to remove it.
Note:Be careful. If the front part is lifted without pushing the amplifier forward, the hook on the rear portion of the mounting section is likely to break.
<How to mount the sensor head>
①Insert the sensor head connector into the inlet until it clicks.
②Fit the cover to the connector.
Sensor head
- The tightening torque should be 0.5 N·m or less.
- When placing the sensor head horizontally or vertically, the reflector must also be positioned horizontally or vertically as shown in Fig. 1 below.
If the sensor head is placed horizontally or vertically but the reflector is leaned as shown in Fig. 2 below, the reflection amount will decrease, which may cause unstable detection.
Fig. 1 Proper positioning
When placing the sensor head horizontally or vertically, the reflector shall also be positioned horizontally or vertically.

Lens attachment for line reflective type (LS-MR1)
Removing method
①Insert a screwdriver into the fixing slot located at the top of sensor head.
②Tilt the screwdriver inserted in Step ① to remove LS-MR1.
Mounting method
- The lens attachment for line reflective type LS-MR1 mounted in the long sensing range line reflective type LS-H22□ is removable.
When LS-H22□ is used without LS-MR1, it will provide the equivalent performance to the long sensing range spot reflective type LS-H21□. In addition, the optional LS-MR1 can be attached to LS-H21□ to obtain the performance equivalent to LS-H22□. - Keep the lens clean of dust, dirt, water, oil, grease, etc.
- Do not apply any excessive force to LS-MR1.
Such force may cause damage.
①The size of upper fixing hook of LS-MR1 is not same as the lower fixing hook. After identifying the upper and lower fixing hooks, insert LS-MR1 upper fixing hook into the fixing slot at the top of sensor head and then insert LS-MR1 lower fixing hook into the fixing slot at the bottom of sensor head.
②After mounting, check that LS-MR1 is properly fixed to the sensor head.
Wiring
- Make sure that the power supply is off while wiring.
- Verify that the supply voltage variation is within the rating.
- Take care that if a voltage exceeding the rated range is applied, or if an AC power supply is directly connected, the sensor may get burnt or damaged.
- Take care that short-circuit or wrong wiring of the load may burn or damage the sensor.
- Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
- Ensure that an isolation transformer is utilized for the DC power supply. If an auto transformer is utilized, the main amplifier or power supply may be damaged.
- Make sure to use the optional quick-connection cable for the connection of the amplifier [connector type LS-401(P) / LS-403]. Extension up to total 100 m 328.084 ft is possible with 0.3 mm2, or more,cable. However, in order to reduce noise, make the wiring as short as possible.
Others
- Do not use during the initial transient time (0.5 sec. approx.) after the power supply is switched on.
- Because the sensitivity is higher in U-LG mode than in other modes, it can be more easily affected by extraneous noise.
Check the operating environment before use. - These sensors are only for indoor use.
- Avoid dust, dirt, and steam.
- Take care that the product does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.
- This sensor cannot be used in an environment containing inflammable or explosive gasses.
- Never disassemble or modify the sensor.
