Safety Guard - Parallel BeamSafety Guard - Cross Beam
  1. Hand Protection
  2. Finger Protection
  3. Protection of Body/Part of Body

These are available in two types. Parallel Beam and Cross Beam. For the same protected height, Cross Beam Light curtains are more sensitive as there are more number of active beams in the same area (explained at the bottom with figure).

Safety Light Curtains / Guards are used for preventing injuries of hand / finger / body part, while working at Power presses for Metal, Processing machines for Wood, Plastic, Leather, Rubber, Glass, etc.; Filter presses, Folding or systems, Rubber molding machines, SPMs, Forging Presses, Injection machines, etc.

Features:

  •  Offers Safety Standard Type 4 when used with Controller
  •  Easy to install & can be mounted in any position. Vertical / Horizontal.
  •  Non-Critical alignment between Emitter & Receivers is possible.
  •  Blanking / bypassing individual channel is provided through software.
  •  System operation is unaffected by mains power fluctuation.
  •  Dirty or Oily screen make your machine off.
  •  Barrier operated on cycles scanning photo-electric infra-red techniques.
  •  Various barrier heights are available for covering 90mm to 1710mm.
  •  Higher covering heights available upon request.
  •  Use of solid state components & special construction technique ensures that barrier is not affected by normal vibration & shock.
  •  Sensor connections are provided through plug in connectors.
  •  Self-Checking circuitry with two outputs continuously monitors failure of any of the beam in the system and stop the machine if failure is detected.
  •  LED indicators are provided of status indication of each channel.
  •  LED indicators are also provided for output and sense.
  •  Choice for suitable Control Unit available as per different working conditions.
  •  Flexible fixing arrangements to suits individual requirements.
  •  Increases productivity while maintaining required safety.
