AC Two-Wire 90-Degree Plastic Cylindrical Photoelectric Sensors

AC two-wire 90-degree plastic cylindrical photoelectric sensors are photoelectric sensors that operate on 20-250 V AC, are connected in series with the load, and emit their light from the side of an M18 plastic housing, perpendicular to the housing axis. They are used to switch a relay or a small AC load by detecting objects in panels without a DC supply and at mounting points with no space behind the sensor. In the AC version of the Lanbao PR18TGS series, diffuse-reflective models with 40 cm, retroreflective models with 3 m and through-beam models with 10 m are offered with NO or NC output. Compare the sensing type, the distance, the NO or NC output and the connection with a 2 m cable or an M12 connector; verify from the manufacturer data that your load current stays within the sensor's load current range. On through-beam models, the emitter unit, the product whose output type is a light source, is a separate product. They must not be confused with the 10-30 V DC version of the same housing with NPN and PNP outputs; the supply and wiring diagram of the two versions are different.

  • 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.
