Plastic-Body Rectangular Photoelectric Sensors Selection Guide: Technical Criteria & Application Standards
Plastic-Body Rectangular Photoelectric Sensors selection guide: technical parameters, mounting and compliance standards, and Lanbao comparison.
Plastic-body rectangular photoelectric sensors are photoelectric sensors that, thanks to an M18 threaded section on the rectangular plastic housing, can be mounted both in an M18 hole and flat against a surface from the side. Because the mounting style is flexible, they are used to detect objects on packaging, labeling and handling lines by attaching to brackets with M18 holes or to machine sheet metal. The Lanbao PSRT series in the category covers three sensing types: 30 cm diffuse reflective, 3 m retroreflective and 20 m through-beam models are powered by 10-30 V DC and give NPN NO+NC or PNP NO+NC output. Choose a PSRT model first by the sensing type suited to the object and the gap, then by NPN or PNP output and 2 m cable or M12 connector connection; also decide in advance whether you will mount it with the M18 thread or from the side. In through-beam models, the product whose output type appears as light source is the transmitter unit and is used together with the receiver. Although this series is mounted with an M18 thread, it is not an M18 photoelectric sensor with a cylindrical housing; verify the dimensions of the rectangular housing against your mounting location from the product data. The Plastic-Body Rectangular Photoelectric Sensors category on Welibaba includes 14 active models from leading manufacturers such as Lanbao.
Key Technical Parameters for Selecting Plastic-Body Rectangular Photoelectric Sensors
To specify the right Plastic-Body Rectangular Photoelectric Sensors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Sensing Distance | 20mt, 3 mt, 30 cm | Verify against project schedule and load calculation |
| Connection Type | 2m Kablo, M12 Konnektör | Verify against project schedule and load calculation |
| Housing Code | PSRT | 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 Rectangular 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 Background Suppression Rectangular Photoelectric Sensors, Diffuse Reflective Rectangular Photoelectric Sensors, Through-Beam Rectangular Photoelectric Sensors.
