Beam axis alignment is easy

using the bright spot light.

This is a coaxial retroreflective sensor with a spot

diameter of approx. "1 mm "0.039 in (at a 1 m

3.281 ft sensing range), so it can measure amounts

remaining on sheet rolls with high precision.

The first visible light spot for a Class 1

type (FDA standards) (as of October 2004 and

based on research conducted by SUNX). This

makes beam axis alignment much easier.

Easy installation

Sensor heads are designed approximately the same size as

general purpose photoelectric sensors and the mounting

method is identical. (Long sensing range spot reflective / Long

sensing range line reflective / Coaxial retroreflective types)

Because their mounting is compatible with general purpose photoelectric sensors,

the mounting brackets for the general purpose photoelectric sensors and the

universal sensor mounting stand can be used.

Assorted mounting brackets available

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.

The long sensing range spot reflective type and long sensing

range line reflective type have a built-in spot-shape adjuster

that enables spot shape adjustment according to the object

for optimal setting.

Spot shape adjustment possible

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.

Note: Because the transmission method varies depending on the

connecting them.

Cable type allows external input

The LS-401-C2 cable-type amplifier is equipped with

external input wires (5-core). It is ideal for using the laser

sensors in places when external teaching or laser light

emission halting is to be carried out, or when using

separately.

External input

Pressing the switch selects or

cancels the operating mode

Moving the switch from side

to side allows items to be

Pressing the switch then

confirms the selected

setting

Only two switches, the large MODE key and the large jog switch, are required for operation.

2 switches enable simple operation

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

saved. Also, LS series sensors can be connected side-by-

side with FX-300 series fiber sensors.

Handy functions made simple for easy, on-site use.

Easy to use complex functions

When sensing at close range or when the target objects are

transparent or minute, adjust the sensor receiving sensitivity

to one of 3 levels for the optimal setting. In addition, changing

the receiving sensitivity will not effect the response time.

New proposal

Accurately sense the minutest variations (M.G.S. function)

By adjusting the hysteresis, convexo-concave parts of

uneven objects can be cancelled enabling more stable

sensing.

The sensor judges any object outside the range of incident

light intensity established by two set threshold values.

Hysteresis mode Window comparator mode

By combining two outputs, wide array of control is possible,

allowing you to detect meandering objects, for example.

Only rapid changes in light received are detected, which

enable the edge of glass, etc. to be detected accurately.

Notes: 1)

This product complies with 21 CFR 1040.10 and 1040.11 Laser Notice No. 50, dated July 26, 2001, issued by CDRH (Center for Devices and

Radiological Health) under the FDA (Food and Drug Administration). For details, refer to the Laser Notice No. 50.

The sensing range is the value for the RF-330 [RF-230 for the LS-H92(F)] reflector. In addition, the sensing range is the possible setting range for the

reflector. The sensor can detect an object less than 0.1 m 0.328 ft [LS-H92(F): 0.2 m 0.656 ft] away. Note that if there are white papers or specular

objects near the sensor head, reflected light from these objects may be received. In such cases, use the M.G.S. function of the amplifier unit to change

the response time or incident light sensitivity.

LS-H22(F) is the model No. for LS-H21(F) long sensing range spot reflective type sensor head combined with the LS-MR1 lens attachment for line

reflective type sensor head, hence LS-H21(F) appears on the sensor head itself.
