Model PRA Diffuse Reflection Photoelectric Sensor

Application

  • Bill detection sensor for ATM
  • Held up hand for water around sensor
  • Held up hand for automatic door sensor
  • Automatic door sensor for held up hand
  • Non-contact switch for food factor
  • Paper detection sensor
  • Object detection of production line

Features

  • Uses infrared light modulation method for increased resistance to ambient light.
  • Small sensor supporting detection at long distances.
  • The output is an open drain type (Nch MOSFET) that can directly open and close the load,
    which facilitates wiring.

International Standards

  • Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.
  • Products is compliant to the RoHS directive.

* Please consult about "change of specification" and "request of specification" of the product.

Usage Precautions

Usage Precautions

  1. If there is a structure that should not be detected in front of the sensor detection surface, install the sensor with
    the light axis shifted approximately 15° from the structure surface.
  2. The sensor is pulse-driven. To ensure good performance, install a 100 μF capacitor between the power supply Vcc
    and GND near the sensor when possible.
  3. Detection distances have been set for each model using a standard detection target of a specific size.
    The detection distances may decrease with smaller detection targets.
    The detection distance also varies depending on the target material. Therefore, check the detection distance
    in advance using the appropriate target, and set the distance taking into account an error margin.
  4. When several photoelectric sensors are used close of each other, leave enough space between them or install light
    interception plates to prevent light interference. Pay also attention to light that may reflect on the floor or the walls.
  5. It is recommended to use black color with low reflectivity for the detection target background.
