MITSUHASHI PS-270 Reflective Detector

Manufacturer: MITSUHASHI CORPORATION
Model: PS-270
This device uses photoelectric reflection to detect printed line marks and boundaries on the web. It is used in combination with Q-series control panels and drive units for controlling web meandering. It is highly resistant to ambient light and enables high-sensitivity detection.

Features
- By employing a large lens, the detection distance has been increased to 30mm and the spot diameter to φ7.5mm. The detection point is easy to see and the position can be easily adjusted.
- The detector incorporates a newly designed circuit, making it unaffected by sunlight, ambient lighting, and other external factors.
- It can also detect gold and silver-colored sheets. The new optical system is now more effective at detecting mark lines on shiny sheets such as gold and silver.
