Accurate Positioning in Medical & Scientific Laboratories
Challenge
Medical and scientific laboratories need a method to ensure that their microwell plates (containing batches of small samples) are accurately positioned in testing machines. Polarized retroreflective sensors work well for leading-edge detection, but many testing machines have a small footprint and are already crowded with internal components. These offer little space for most sensors on the market.
Solution
The miniature Q2X LPF is a polarized retroreflective sensor small enough to fit inside many types of machines that cannot accommodate larger sensors. In addition to its reduced size, the sensor offers a fast response time of 600 μs, which ensures accurate positioning relative to the known speed of conveyors. With its bright, visible red LED, the sensor is easy to align. By using retroreflective sensing, the Q2X can detect microwell plates of any color, shade, or reflectivity.
