IFM Electronic (UK) introduces a new design that combines stainless steel and plastics in a range of photoelectric sensors for universal use. The choice of models includes very precise background suppression up to 1.8m, through to long-range versions for general applications where no setting is needed. Precise background suppression versions feature a range of 1.4m, using a potentiometer, and 1.8m with a push-button control. The through-beam versions reach 20m, and the retro-reflective devices cover 7m or more. All devices are sealed to a minimum of IP67. The plug can be rotated by 270 degrees so that it can be aligned in any direction.
