At a glance
• Accurate adjustment of the operating distance due to easy operation of the 3-turn
potentiometer
• Reliable detection of objects of all types regardless of their reflective properties
• Minimum black/white shift, less than 10% under 80 mm
Your benefits
• Precise, repeatably accurate switching points with a small, brilliant and sharply
defined light spot
• Universal use, since a minimum black/white shift allows the sensor to be used
irrespective of object contours and backgrounds
• High throughput and less downtime due to the sensor's ability to suppress active
and passive interference in industrial environments.
• The 45-degree tilted cable entry offers maximum installation flexibility with
additional soft rubber bearings to absorb vibrations and tensile loads
• The powerful PinPoint LED permits reliable detection of jet-black and poorly
reflective objects
