The Fife H3218 center-guide detector provides a signal proportional to the center position of a strip of material; independent of material width. Two models of the H3218 are available; depending upon light source choice. The H3218 is for use with the H3137 family of fluorescent light sources. An enhanced version, the H3218E, is for use with the H3157E LED light source. Advanced signal processing allows the H3218 to discriminate between the pulsed light from either the H3137 or H3157 and other sources of light.H3218 Center-Guide Detector SpecificationsPower Requirements10 to 30 Vdc at 3.3 wattsAnalog Output:+/- 10 Vdc proportional to strip centerlineStatus Output:Contact closure indicates normal detector operationRecommended Gap with Light Source:2 to 10 feet
