2) Model-by-Model Explanation

1. E2B-M30LN30-WZ-B1

• Housing: M30 threaded

• Sensing distance: 30 mm (long range)

• Output type: PNP

• Switching mode: Normally Open (typical for B1)

• Connection: Pre-wired cable type

Application:
Used when longer sensing gap is required for large metal objects. Suitable for conveyors, large fixtures, or robotic approach detection where mounting distance cannot be close.

2. E2B-M30LN30-WZ-C1

• Housing: M30 threaded

• Sensing distance: 30 mm

• Output type: PNP

• Connection: M12 connector type (quick disconnect)

Difference from B1:
Electrical performance is the same, but C1 uses connector style instead of fixed cable. Suitable for installations requiring easy replacement or maintenance.

3. E2B-M30LS15-WZ-B1

• Housing: M30 threaded

• Sensing distance: 15 mm

• Output type: PNP

• Connection: Pre-wired cable

This is a medium sensing range version (shorter than LN30).
Used when 30 mm is too long and tighter detection control is needed.

4. E2B-M30LS15-WZ-B2

• Housing: M30 threaded

• Sensing distance: 15 mm

• Output type: PNP

• Switching mode: May differ from B1 (often Normally Closed variant depending on region code)

• Connection: Pre-wired cable

Difference from B1:
Typically differs in switching logic (NO vs NC). Always confirm specific datasheet for B1 vs B2 logic configuration.

5. E2B-M30LS15-WZ-C1

• Housing: M30 threaded

• Sensing distance: 15 mm

• Output type: PNP

• Connection: M12 connector type

Same sensing performance as LS15-WZ-B1, but uses connector version instead of cable.

3) Key Technical Comparison

4) LN30 vs LS15 Difference

Longer sensing distance requires larger metal target size for reliable detection.

5) Output Type Explanation (WZ)

All models shown are WZ, meaning:

• PNP output

• When metal is detected → output switches to +24 V

• Designed for PLC sourcing input configuration

6) Industrial Application Examples

These M30 sensors are typically used for:

• Large metal part detection

• Heavy press machine feedback

• Conveyor steel plate detection

• Robot fixture position confirmation

• End-of-travel detection on large actuators

• Gantry position sensing

7) Installation Considerations

• Ensure sufficient clearance from surrounding metal surfaces

• Confirm metal target size is appropriate for 15 mm or 30 mm range

• Use correct PLC input configuration for PNP output

• Secure M30 threaded mounting to prevent vibration movement

Model: E2B-M30LN30

3. Decoding the Model Code

The M30 body allows larger sensing distance compared to smaller M8, M12, M18 types. A 30 mm range is considered long for inductive detection, suitable for applications where the sensor cannot be mounted close to the target.

4. Sensing Distance Context

Inductive sensors saturate detection quickly. Standard E2B sensors have short sensing distances (3–8 mm or 8–15 mm).
The E2B-M30LN30 with 30 mm sensing means it has been engineered with a stronger oscillator and larger coil to detect metal targets at a significantly greater distance.

This can be useful when:

• The metal target moves variably within a larger gap

• The mounting position cannot be close to the moving target

• Larger objects require detection without precise alignment

5. Output Types and Polarity

This specific model (E2B-M30LN30) can be ordered with different output polarities:

Make sure to match the output type with your controller’s input logic:

• NPN (sinking) feeds current to ground when active

• PNP (sourcing) feeds positive voltage when active

6. Protection and Environment

The E2B series, including the M30 long range version, typically has:

• IP67 rating: dust tight and protected against water jets

• High durability for industrial factory floor use

• LED indicator for easy commissioning and troubleshooting

7. Wiring and Electrical Setup

These sensors normally have four wires on pre-wired cable or M12 connector versions:

Important: Confirm the exact wiring with the specific data sheet for the suffix you choose.

8. Typical Applications

The long sensing distance of this model makes it suitable for:

• Detecting large metal plates on conveyors

• Position feedback for fixtures with variable gap

• Detecting metal parts in press to conveyor transfer

• Robot approach detection with gap tolerance

• Overhead gantry detection where sensor cannot be close

9. Installation and Setup Tips

1. Mount perpendicular to target face to maximize sensing distance.

2. Avoid parallel metal surfaces close to the sensor body (for flush types, adjacent metal must be spaced per datasheet).

3. Ensure target is within the 30 mm range and is large enough (larger metal surfaces increase effective range).

4. Choose correct output type (NPN/PNP) to match PLC/PLC input card configuration.

5. Use LED indicator to confirm detection status during commissioning.
