AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors

AC two-wire plastic-body cylindrical photoelectric sensors are photoelectric sensors with an M18 threaded plastic housing that are both powered and switch the load over the same two conductors at 20-250 V AC. They are used to drive a relay or a small AC load in door, small conveyor and stand-alone machine circuits where a separate DC power supply is not wanted. The category includes models from the Lanbao PR18TS series with 10 cm and 40 cm diffuse-reflective, 3 m retroreflective and 10 m through-beam distances and NO or NC output. First choose the sensing type and the distance, then the NO or NC output that suits your circuit logic and the connection with a 2 m cable or an M12 connector. If the load current is very small, the sensor's off-state leakage current can keep the load energized unintentionally; therefore check the leakage current and minimum load current values in the manufacturer data. AC two-wire plastic models with an M30 housing and PR18TS models with 10-30 V DC supply are in separate categories; they must not be confused because of the similar product codes.

How to choose AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors

AC two-wire plastic-body cylindrical photoelectric sensors are photoelectric sensors with an M18 threaded plastic housing that are both powered and switch the load over the same two conductors at 20-250 V AC. They are used to drive a relay or a small AC load in door, small conveyor and stand-alone machine circuits where a separate DC power supply is not wanted.

  • 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.
