Metal-Body Cylindrical Photoelectric Sensors

Metal-body cylindrical photoelectric sensors are photoelectric sensors with an M18 or M30 threaded metal housing, powered by 10-30 V DC and providing an NPN or PNP transistor output. They are connected to a PLC input to detect objects on machine frames exposed to mechanical shock and vibration, on heavy conveyor lines and at mounting points exposed to the elements. The Lanbao PR18T and PR30T models on this page come with sensing distances such as 10 cm, 40 cm and 100 cm for the diffuse-reflective type, 3 m and 5 m for the retroreflective type, and 20 m and 40 m for the through-beam type. Choose the M18 or M30 housing according to the mounting hole and the required distance, the sensing type according to the object surface, the NPN NO+NC or PNP NO+NC output according to the PLC input card, and the connection according to whether it is cabled or has an M12 connector. For example, the 40 m through-beam and 5 m retroreflective models in this category have an M30 housing. The 20-250 V AC two-wire versions of the same PR18T and PR30T housing codes are in a separate category and are not a substitute for the DC models.

How to choose Stainless Steel Cylindrical Photoelectric Sensors

Metal-body cylindrical photoelectric sensors are photoelectric sensors with an M18 or M30 threaded metal housing, powered by 10-30 V DC and providing an NPN or PNP transistor output. They are connected to a PLC input to detect objects on machine frames exposed to mechanical shock and vibration, on heavy conveyor lines and at mounting points exposed to the elements.

  • 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.
