Diffuse Reflective Rectangular Photoelectric Sensors

Diffuse reflective rectangular photoelectric sensors house the transmitter and receiver in the same rectangular housing and switch their output when the light they send is reflected back from the object itself. They are used to detect objects with single-side mounting at conveyor, feeding and packaging points where no reflector or receiver can be placed on the other side. The category includes Lanbao and Isıso branded models with sensing distances such as 30 cm, 100 cm and 200 cm, with PNP NO+NC and NPN NO+NC outputs and 10-30 V DC and AC/DC supply. Choose the model by the sensing distance required for the object's color and surface, the supply voltage, the NPN or PNP output that suits your PLC input, and cable, M8 or M12 connector connection. The catalog distance is given for a light-colored reference surface, so the distance reached is shorter for dark, matte or small objects. This type can also be affected by shiny surfaces in the background, so it does not replace a background suppression photoelectric sensor.

How to choose Diffuse Reflective Rectangular Photoelectric Sensors

Diffuse reflective rectangular photoelectric sensors house the transmitter and receiver in the same rectangular housing and switch their output when the light they send is reflected back from the object itself. They are used to detect objects with single-side mounting at conveyor, feeding and packaging points where no reflector or receiver can be placed on the other side.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
