Diffuse Reflective Cylindrical Photoelectric Sensors

Diffuse reflective cylindrical photoelectric sensors combine the transmitter and receiver in a single threaded cylindrical housing and switch with the light returning from the object itself. Because they need no element on the opposite side, they are used for part presence inside machines, product arrival on a feeding line and short-distance counting. The category includes Isıso and Lanbao branded M12 and M18 housing models with sensing distances such as 100 mm, 200 mm, 400 mm and 800 mm, powered by 10-30 V DC or 90-250 V AC. Choose the housing diameter by the mounting hole, the sensing distance by the object's color and size, the output by NPN or PNP input type and the need for NO, NC or NO+NC, and the connection by whether it is cable or M12 connector. Dark and matte surfaces reflect less light, so the same sensor detects these objects from a shorter distance. It does not replace a retroreflective or through-beam photoelectric sensor for monitoring gaps at the meter level; its sensing distance is shorter than these types.

How to choose Diffuse Reflective Cylindrical Photoelectric Sensors

Diffuse reflective cylindrical photoelectric sensors combine the transmitter and receiver in a single threaded cylindrical housing and switch with the light returning from the object itself. Because they need no element on the opposite side, they are used for part presence inside machines, product arrival on a feeding line and short-distance counting.

  • 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.
