Miniature OJ sensors line has been expanded to include models with polarized retro-reflective sensing technology that detect clear objects such as glass, transparent film and see-through bottles. Sensing technology incorporates acute sensitivity that enables the sensor to accurately detect clear objects. When paired with the company''s 50 x 50 mm reflector, the OJ''s sensing range will reach 1.5 meters. The sensor''s microprocessor-based pushbutton adjustment simplifies programming and reduces setup time. Sensitivity is automatically calibrated by positioning the sensor in front of a reflector and pressing the pushbutton twice. A target is not required during initial setup to establish sensitivity.
