A new type of laser sensors that makes maintenance and preventive maintenance easy!

■Direct connection with communication unit for CC-Link SC-GU2-C

CC-Link communication is possible through the connection to SC-GU2-C. By having the configurations saved as "Configuration file" before equipment shipment, later on when it comes to exchanging the sensors, the configurations can be simply written in through CC-Link. When connecting with digital fiber sensors FX-301/305 or digital pressure sensors DPS-401/402, batch data communication can be carried out.

■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 manhours for maintenance.

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 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.

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. The connections and man-hours for the intermediate terminal block setup can be reduced and valuable space is saved. Also, LS-403 can be connected side-by-side with fiber sensors FX-300 series, pressure sensors DPS-400 series, or other connector type sensors.

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

Using the emission halt function, the laser beam can be stopped via external input, e.g. when a spot appears within the visual range of an image processor.

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.
