The emitter-receiver photocells of the Sx-F/G-SG-ST series have been homologated to function with the control units of the SG-BWS series that together form a safety system respectively of Type 2 and Type 4 conforming with the EN 954-1 and EN ISO 13849-1 Standards. The photocells are available in the M18 tubular plastic format with infrared emission of the S5 series for distances reaching 8m, M18 plastic tubular format with laser emission of the SL5 series with operating range reaching 40m, and MAXI format with infrared emission of the new S300 series with operating range reaching a respective ly 50m for Type 2 and 40m for Type 4 models. Together with S300 standard models DEFOGGING MODELS with heated front glass are available for applications where sudden changes of the temperature in the nearby of the sensor are causing condensation. All models are equipped with M12 4-pole connector: no cable or terminal block models are available. LEDs signal
both the operating status and correct alignment of the safety photocells.
