Plastic-Body Rectangular Photoelectric Sensors

Plastic-body rectangular photoelectric sensors are photoelectric sensors that, thanks to an M18 threaded section on the rectangular plastic housing, can be mounted both in an M18 hole and flat against a surface from the side. Because the mounting style is flexible, they are used to detect objects on packaging, labeling and handling lines by attaching to brackets with M18 holes or to machine sheet metal. The Lanbao PSRT series in the category covers three sensing types: 30 cm diffuse reflective, 3 m retroreflective and 20 m through-beam models are powered by 10-30 V DC and give NPN NO+NC or PNP NO+NC output. Choose a PSRT model first by the sensing type suited to the object and the gap, then by NPN or PNP output and 2 m cable or M12 connector connection; also decide in advance whether you will mount it with the M18 thread or from the side. In through-beam models, the product whose output type appears as light source is the transmitter unit and is used together with the receiver. Although this series is mounted with an M18 thread, it is not an M18 photoelectric sensor with a cylindrical housing; verify the dimensions of the rectangular housing against your mounting location from the product data.

How to choose Plastic-Body Rectangular Photoelectric Sensors

Plastic-body rectangular photoelectric sensors are photoelectric sensors that, thanks to an M18 threaded section on the rectangular plastic housing, can be mounted both in an M18 hole and flat against a surface from the side. Because the mounting style is flexible, they are used to detect objects on packaging, labeling and handling lines by attaching to brackets with M18 holes or to machine sheet metal.

  • 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.
