The 44B photoelectric sensor incorporates adjustable background or foreground suppression. The sensor is designed for industrial applications requiring reliable detection of targets close to a surface - such as a conveyor - that must be ignored by the sensor.
The 44B photoelectric sensor is available in two sensing modes: background suppression up to 300 mm and foreground suppression up to 200 mm. The background suppression sense mode will change its output state when it 'sees' reflected light from the target. The foreground suppression sense mode uses the background as a reflector and changes its output state when a target blocks this reflector.
The background suppression sense mode is best suited to the detection of light targets against a less reflective background - such as detecting missing bottle caps. Foreground suppression should be used when looking at a dark or irregularly shaped target against a highly reflective background - such as products on a reflective white conveyor belt.
With its unique optical design, IP67-rated housing and fast 1 ms response time, the 44B sensor helps ensure high-quality production line output with minimum false triggers.
