Broad spectrum white LED High-speed, 40kHz switching Teach function Numeral display (on some models) DESCRIPTION CNTX CONTRAST SENSOR OVERVIEW Our contrast sensor increases process throughput with high-speed, accurate, and reliable contrast differentiation. The CNTX™ combines a broad-spectrum light source, small spot size, and fast response to achieve high-speed contrast differentiation of both neutral and color targets. The CNTX™ employs our field-proven, patented technology, for effective detection of registration marks, glossy surfaces, cap inserts, date codes, and sorting of the product by color in many industrial applications. The durable plastic case and polycarbonate lens provide robust construction expected in an industrial environment. The CNTX™ (also known as a Registration Mark Sensor) combines the small spot size of 3mm (0.4MM SPOT SIZE also available) and fast response times to achieve high-speed contrast differentiation of both neutral and color targets. The sensor provides a numerical display of 50 grayscale levels. The broad-spectrum light source allows accurate detection of a wide range of colors against any background. The flexibility of the CNTX™ makes it easy to set up in a wide variety of printing, packaging, and converting applications. CONTRAST SENSOR APPLICATIONS: Detect registration marks Confirm the presence of date codes Detect glossy surfaces Sort products by color Detect cap inserts Read our APPLICATION NOTE on how contrast sensors detect transparent objects.
