AC Two-Wire 90-Degree Plastic Cylindrical Photoelectric Sensors Selection Guide: Technical Criteria & Application Standards
AC Two-Wire 90-Degree Plastic Cylindrical Photoelectric Sensors selection guide: technical parameters, mounting and compliance standards, and Lanbao comparison.
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. The AC Two-Wire 90-Degree Plastic Cylindrical Photoelectric Sensors category on Welibaba includes 14 active models from leading manufacturers such as Lanbao.

Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Cylindrical Photoelectric Sensors.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as AC Two-Wire Metal Cylindrical Photoelectric Sensors, AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors, AC Two-Wire Plastic Cylindrical Photoelectric Sensors.
