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]

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 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-500FX-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.

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.
Threshold tracking function saves maintenance time

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.
4 new modes enabling wide array of sensing

[Window comparator mode]
The sensor judges any object outside the range of incident light intensity established by two set threshold values.
4 new modes enabling wide array of sensing

[2 independent output modes]
By combining two outputs, a wide array of control is possible, allowing you to detect meandering objects, for example.
4 new modes enabling wide array of sensing

[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.
Emission halt function

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.
Cable type allows external input

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.
