SAFETY LIGHT CURTAINS

SAFETY LIGHT CURTAINS / SAFETY GUARDS

MODELS FOR BODY PROTECTION

Model :     With 90 mm Pitch

DETAILS

Electronic Switches offers new generation Safety Light Curtains / Safety Guards based on advanced micro controller technology. These are available in two types. Parallel Beam ( LC : type II beam ) and Cross Beam   ( LX : type x 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.

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 & Receiver.
- Blanking / By-Passing individual channel is provided through software.
- System operation is unaffected by mains power fluctuations.
- Machine OFF if screen is too dirty or oily.
- Barrier operates on cyclic scanning photo-electric infra-red techniques.
- Various barrier heights are available for covering 90 mm to 1890 mm .
- Higher covering heights available upon request.
- Use of solid state components & special construction technique ensures that barrier is not affected by normal vibrations & shocks.
- 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 Indications are provided for status indication of each channel.
- LED indications are also provided for each output.
- Choice for suitable Control Unit available as per different working conditions.
- Flexible fixing arrangements to suit individual requirement.
- Increases productivity while maintaining required safety.
