Laserheads
|
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 ultra-compact 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 polarised filters
- Reflective Type: Spottyp und Linetype
- Redlight-Laserdiode laser class 1 or 2
- Laser focus and line adjustable
- Ultra-compact size
Accessory: - Mounting bracket
- Lens LSMR1 for line reflection type

Controller
|
|
A jog switch and a mode key are a convenient way to program all the controller functions; programming is easy with a dual, two-colour, 4-digit LCD display and several LED displays. A characteristic of the LS series is the so-called M.G.S. function, which allows the dynamic range of the receiving sensitivity to be adjusted. This prevents 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). Characteristics: - Double 4 digit display for current and threshold values
- Mode-key and jog switch for simple adjustment
- Response time max. 80µs
- Four output modes
- Timer
- Cross talk prevention
- External teach In (cable type)
- Key-Lock function
- External switch off of laser beam
- Side by side mounting with FX300 series possible
- Cable or connector types
Accessories: - Main- and sub cable for side by side mounting (1 / 2 / 5 m)
