Both Control output and analog output provide |
Feature
- Built-in amplifier and low-cost
- High precision detection can be made by applying PSD(Position Sensitive Detector)
- Protective structure is IP67
- Easy setting(Upper limit and lower limit) can be made by pushing teaching button
- Wide line-up with 30mm to 250mm(4 kinds) as detection distance
