90-Degree Metal Cylindrical Photoelectric Sensors

Cylindrical metal 90-degree photoelectric sensors are photoelectric sensors with angled optics that have an M18 threaded metal housing and send their light perpendicular to the housing axis, that is, from the side. They are used to detect objects, with the housing laid parallel to the surface, inside machines and along conveyor edges where there is not enough depth behind the sensor for the housing length. The category includes Lanbao PR18TG series 40 cm diffuse reflective and 20 m through-beam models, powered by 10-30 V DC, with NPN NO+NC and PNP NO+NC outputs. Choose the sensing type and distance by the application, the output by the PLC input type and the connection by whether it is a 2 m cable or M12 connector, and compare the light exit direction with your mounting position. In through-beam models, the one with a light source output is the transmitter and the one with an NPN or PNP output is the receiver. For models with plastic in the product name, verify the housing material from the product code and the manufacturer's data before ordering. It fits a hole of the same diameter as straight-optics M18 photoelectric sensors, but because the light direction is different it does not replace an existing straight model.

How to choose 90-Degree Metal Cylindrical Photoelectric Sensors

Cylindrical metal 90-degree photoelectric sensors are photoelectric sensors with angled optics that have an M18 threaded metal housing and send their light perpendicular to the housing axis, that is, from the side. They are used to detect objects, with the housing laid parallel to the surface, inside machines and along conveyor edges where there is not enough depth behind the sensor for the housing length.

  • 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.
