Their special features make them particularly attractive as measured value displays for photoelectric length gauges in manufacturing environments and in measuring and testing labs. However, they also serve for position display in simple positioning tasks such as the infeed of a circular saw or the stroke of a press, and with their switching inputs and outputs they are also found in simple automation environments. One version model can switch from linear to angular display values for rotary and angle encoders.
