Rectangular Type DC 3-Wire Inductive Sensors Selection Guide: Technical Criteria & Application Standards
Rectangular Type DC 3-Wire Inductive Sensors selection guide: technical parameters, mounting and compliance standards, and Lanbao comparison.
Rectangular type DC 3-wire inductive sensors are metal sensing sensors with a slim rectangular 8x8 mm cross-section housing, mounted on a flat surface. They are used to detect the presence or position of metal parts in narrow slides, holders and small machine elements where a hole cannot be drilled for a threaded cylindrical housing. The Lanbao models in this category measure 8x8x25 mm, 8x8x40 mm and 8x8x50 mm; they have flush heads, and a 1.5 mm sensing distance and 2 kHz switching frequency are specified in the product data. Choose the housing length, NPN or PNP output and 2 m cable or M8 connector connection according to the mounting space and the type of the PLC input card. The supply is 10-30 V DC, and the output is normally open. A rectangular type sensor does not replace 40x40 mm square-housing sensors that offer distances such as 40 mm; its sensing distance is around 1.5 mm and the target must pass close to the sensor. The Rectangular Type DC 3-Wire Inductive Sensors category on Welibaba includes 16 active models from leading manufacturers such as Lanbao.
Key Technical Parameters for Selecting Rectangular Type DC 3-Wire Inductive Sensors
To specify the right Rectangular Type DC 3-Wire Inductive Sensors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Sensing Distance | 1.5 mm | Verify against project schedule and load calculation |
| Connection Type | 2m Kablo, M8 Konnektör | Verify against project schedule and load calculation |
| Frequency Type | 2 kHz | Verify against project schedule and load calculation |
| Sensor Head Type | Düz | 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 Inductive 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 2-Wire Inductive Sensors, Analog Inductive Sensors, DC 2-Wire Inductive Sensors.
