DC 2-Wire Inductive Sensors Selection Guide: Technical Criteria & Application Standards
DC 2-Wire Inductive Sensors selection guide: technical parameters, mounting and compliance standards, and Lanbao, Isıso comparison.
DC 2-wire inductive sensors are proximity sensors that have no separate supply wire, work connected in series with the load and detect metal objects without contact. They are connected to a PLC input where existing two-core wiring is to be kept and at points where they replace a mechanical limit switch. This category includes Lanbao and Isıso branded M8, M12, M18 and M30 models with flush or non-flush heads; sensing distances are values such as 1.5 mm, 2 mm, 4 mm, 5 mm, 10 mm and 15 mm. Choose the housing diameter, head design, sensing distance, NO or NC output and switching frequency according to the mounting location and the input to be connected. A two-wire sensor has a voltage drop across it when on and a small leakage current passes through the circuit when off; verify from the manufacturer's data that the PLC input works correctly with these values. A DC 2-wire sensor is not a three-wire sensor with an NPN or PNP output; it has no separate output wire and is powered through the load circuit. The DC 2-Wire Inductive Sensors category on Welibaba includes 15 active models from leading manufacturers such as Lanbao, Isıso.
Key Technical Parameters for Selecting DC 2-Wire Inductive Sensors
To specify the right DC 2-Wire Inductive Sensors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Sensor Head Type | Düz, Düz (flush), Çıkık | Verify against project schedule and load calculation |
| Sensing Distance | 1.5 mm, 10 mm, 15 mm, 2 mm | Verify against project schedule and load calculation |
| Connection Type | 2m Kablo, Kablolu | Verify against project schedule and load calculation |
| Frequency Type | 1 kHz, 200 Hz, 300 Hz, 500 Hz | 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, Rectangular Type DC 3-Wire Inductive Sensors.
