Laser Sensors LS
LS User-friendly, advanced high precision laser sensing!
Features 4 types of identically sized sensor heads available They are approximately the same size as general purpose photoelectric sensors, and the mounting method is identical.
Accurately senses the minutest variations 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 affect the response time.
Easy setting, dual display
Long sensing range line reflective type: LS-H22 Long sensing range spot reflective type: LS-H21 (Class 1 type is also available.)
Coaxial retroreflective type: LS-H91 Long sensing range coaxial retroreflective type: LS-H92
Equipped with 2 large 4-digit digital displays. While checking the current light-receiving amount (red display), the optimal threshold value (green display) can be set easily.
(Class 1 type is also available.)

Wiring and space savings New coaxial reflective type with a long sensing range of 30m The introduction of the LS-H92 long sensing range coaxial reflective type sensor means that even longer sensing ranges are now possible.
The quick-connection cables enable reductions in wiring (connector type). The connections and man hours for the intermediate terminal block setup can be reduced and valuable space saved. Also, LS series amplifiers can be connected side-by-side with FX-300 series fiber sensors.

Spot size adjustment The long sensing range spot reflective type and long sensing range line reflective type have a built-in spot-size adjuster that enables spot size adjustment according to the object for optimal setting.

Laser Sensors Interference prevention function
Emission halt function
External teaching function
The automatic interference prevention function protects against interference among up to 4 sensors.
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.
Teaching can be conveniently performed externally for laser sensors installed inside a device.
