Fife SE-15 Visible Light Sensor
Small, yet accurate, the SE-15 Visible Light Sensor is perfect for web applications where exact guiding is required and space is limited. With a control range of 10.2 mm (0.4 inch), this compact, lightweight sensor is best suited for edge guiding opaque, transparent, or reflective materials in most unwind and rewind applications.
This medium-gap reflex sensor utilizes a reflector mounted on the opposite side of the web and a co-axis optical visible red light for transmitted and received light beams. The effective gap between reflector and sensor can range from 25 mm (1 inch) up to 1 meter (39 inches). The sensor light signal is processed to filter out ambient and reflected light to provide reliable and accurate performance.
