SD3 safety laser scanner

  • SD3 safety laser scanner

Guard large danger zones cost-effectively

The Panasonic SD3 safety laser scanner is a cost-effective alternative for guarding danger zones. It can be used flexibly in confined spaces and for areas where the danger zone changes.

The SD3 can monitor an area within an angle of up to 190°, and divides it into 2 zones:

  • a warning zone within a radius of 15m, and
  • a protection zone within a radius of 4m.

The contours of these zones can be configured precisely for any application. Up to eight zone patterns can be set and activated at any given time, even during operation.

The reference boundary function memorizes the position of stationary objects and establishes a virtual boundary. It also monitors beam alignment after installation and issues an alarm if the beam becomes misaligned.

Characteristics:

  • Warning zone, max. radius 15m
  • Protection zone, max. radius 4m
  • Adjustment of response times enables interference prevention
  • Up to 8 freely switchable zone patterns
  • Smallest size in his class: W140 × H195 × D135mm


Accessories:

  • Configuration plug (optional), handy for storing, recovering and transferring settings
  • PC connection cable
  • Mounting bracket
  • Operation check tool to simulate the digital inputs and monitor the SD3 outputs
  • Cleaning set

Operating principle

A pulsed laser beam (3) is discharged from the emitting element (T) to the reflectors (1) and onto a rotating mirror. The rotating mirror (2) scans the laser as it rotates. The diffuse reflection (4) from the sensing object is then returned to the receiving element (R) by means of the rotating mirror. The location of the sensing object (SO) is measured based on the travel time of the laser and the angular information of the rotating mirror. The monitoring area (max. 190°) is divided into 528 segments of 0.36° each by the rotating mirror. An additional sensor (5) detects dirt on the lens’ surface to guarantee functionality.
