Through-Beam Cylindrical Photoelectric Sensors Selection Guide: Technical Criteria & Application Standards
Through-Beam Cylindrical Photoelectric Sensors selection guide: technical parameters, mounting and compliance standards, and Lanbao, Isıso comparison.
Through-beam cylindrical photoelectric sensors are photoelectric sensor pairs made up of a threaded cylindrical-housing transmitter and a receiver of the same size, which detect an object when the beam between them is interrupted. Because detection does not depend on the object's color or surface shininess, they are used on conveyors where opaque objects are counted, at machine entrances and exits and at passage points. The category includes Lanbao branded M12 housing, metal and plastic models with a 10 m sensing distance, and Isıso branded M18 housing models, all powered by 10-30 V DC. In Lanbao products, the model whose output type is light source is the transmitter, and the model with NPN NO+NC or PNP NO+NC output is the receiver. Compare the gap between transmitter and receiver, the housing diameter and material, the receiver's NPN or PNP output and the 2 m cable or M12 connector connection. Both housings must be powered and aligned on the same axis; where single-point mounting is required, it does not replace a diffuse reflective photoelectric sensor. The Through-Beam Cylindrical Photoelectric Sensors category on Welibaba includes 14 active models from leading manufacturers such as Lanbao, Isıso.
Key Technical Parameters for Selecting Through-Beam Cylindrical Photoelectric Sensors
To specify the right Through-Beam Cylindrical Photoelectric Sensors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Output Type | Işık Kaynağı, NPN NO+NC, PNP NO+NC | Verify against project schedule and load calculation |
| Sensing Distance | 10mt, 500 mm | Verify against project schedule and load calculation |
| Connection Type | 2m Kablo, Kablolu, M12 Konnektör | Verify against project schedule and load calculation |
| Housing Code | PR12T, PR12TS | 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-Body Cylindrical Photoelectric Sensors.
