31551 Heavy Duty Edge Guide Sensor

The Model 31551 Heavy Duty Edge Guide Sensor is specifically designed for heavy duty strip guiding applications, where maximum versatility is required. The sensor consists of two sturdy cast steel housings which are mounted separately, providing greater installation flexibility. One housing contains the photocell and is available in two options, either photoresistive (cadmium sulfide) or photovoltaic (silicon solar cell). The other housing contains the light source. 

Improved optical system of Model 31551 allows for lamp and photocell housings to be spaced up to 144 inches apart. This provides the maximum in physical protection. 

The Model 31551 Edge Guide Sensor is intended to be used with the GPE Model 33130D Digital Controller or GPE 33130 Analog Webguide Controller, which provide the operating signal for GPE’s Electro-hydraulic or Powerpulse type controllers. The Electronic Controller provides for three control modes, such as Proportional Speed Floating, Predictive Position Feedback or Two Speed Floating. In addition, signals are acceptable for centerguide operation when two sensors are used.


  • High Sensitivity: Detects better than .005″ of lateral strip displacement

  • Versatility: Sensor provides signal for Electrohydraulic or Powerpulse Controller. Photocell and lamp housings can be mounted up to 144 inches apart. Electronic Controller provides for choice of three control modes and choice of edge or centerguide operation

  • Reliability: Photocell and lamp operate at low voltage for increased life
