GPE 31850 LED Edge Guide Sensor

 GPE comes with over 70 years of engineering know-how and innovative design experience. Combining the latest advances in High-Tech research and development with years of field-proven experience, you are assured of a top-quality, reliable, and durable system capable of withstanding even the harshest of environments. This is a standard established for all of the equipment sold within the L&J Technologies family of products. Every product is designed and manufactured to last.

Modern process lines contain hundreds of feet of strip moving at high line speeds through narrow roll faces to be wound on enormous coils. Only the most accurate, automatic guiding system can protect such a mill against the product damage and process downtime caused when the strip runs off the rolls. Built for long life under the toughest possible working conditions, they’re backed up by a large service organization. GPE benefits from years of unparalleled strip guide leadership. Their continued top performance is assured by the broadest, deepest knowledge of strip guiding experience anywhere in the world.



The Model 31850 LED Edge Guide Sensors are specifically designed for strip guiding applications where maximum versatility is required.

The sensor is available in the standard gap (10′ maximum) or wide gap (20′ maximum) housing configurations for any application. Either housing configuration is extremely durable. Both sensors consist of two separate housings that contain the light source and the detector respectively.

The use of a solid-state source and detector units ensures reliability and eliminates periodic service. The light source is modulated by frequency beyond the range of ambient light sources. The detector circuitry includes a notch filter which permits detecting only the source light frequency. All external ambient light frequencies are restricted from entering the sensors.

The standard gap housing’s light source and detector can be spaced from 3″ to 120″ and the wide gap housing’s range is 3″ and 240″, for maximum flexibility. The Model 31850 Edge Guide Sensors are intended to be used with a GPE Controls Electronic Controller, which provides the operating signal.

When two sensors are used, the center guide operation is also possible.

The Model 31850 can also be used to retrofit existing GPE Controls Model 31550 and Model 31551 Edge Guide Sensors, while still using existing housings.
