LS-400 laser sensor

  • LS-400 laser sensor

Laser heads

The LS series uses a highly focused and concentrated laser beam and a coaxial optical lens system to enable it to detect extremely small objects a long distance away. Choose from ultracompact sensor heads as a reflective light barrier with a polarisation filter or as a reflective sensor with a light spot or light band.

The LS series is particularly suitable for monitoring or detecting extremely small objects on a conveyor belt, for monitoring the sizes of objects and for monitoring edge positions in industrial production.

Characteristics:

  • Retroreflective: coaxial lenses with polarized filters
  • Reflective types: spot type and line type
  • Red light laser diode laser class 1 or 2
  • Laser focus and line adjustable
  • Ultracompact size

Accessory:

  • Mounting bracket
  • Lens LSMR1 for line reflection type

Controller

A jog switch and mode key allow you to conveniently program all controller functions; programming is easy with a dual, two-colour, 4-digit LCD display and several LED displays. The LS series' M.G.S. function, which allows the receiving sensitivity's dynamic range to be adjusted to prevent oversaturation of the reflected light intensity (transparent objects in the case of reflective light barriers or shiny objects in the case of reflective sensors, for example).
