AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors Selection Guide: Technical Criteria & Application Standards
AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors selection guide: technical parameters, mounting and compliance standards, and Lanbao comparison.
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. The AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors category on Welibaba includes 18 active models from leading manufacturers such as Lanbao.
Key Technical Parameters for Selecting AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors
To specify the right AC Two-Wire Plastic-Body Cylindrical Photoelectric Sensors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Sensing Distance | 10 cm, 10mt, 3 mt, 40 cm | Verify against project schedule and load calculation |
| Connection Type | 2m Kablo, M12 Konnektör | Verify against project schedule and load calculation |
| Housing Code | PR18TS | Verify against project schedule and load calculation |
| Model Type | Cisimden Yansımalı, Karşılıklı, Reflektörlü | Verify against project schedule and load calculation |
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 90-Degree Plastic Cylindrical Photoelectric Sensors, AC Two-Wire Metal Cylindrical Photoelectric Sensors, AC Two-Wire Plastic Cylindrical Photoelectric Sensors.
