Product Information

Full details

The Omron E3Z-LS86 is a background suppression photoelectric sensor designed for precise object detection in industrial automation. It's ideal for applications requiring reliable sensing of objects with varying colors or reflectivity, offering a detection range of 20mm to 200mm. A key benefit is its ability to ignore background objects, reducing false triggers. However, its effectiveness can be influenced by highly reflective surfaces directly behind the target object.

FAQs

What is the maximum sensing distance for the E3Z-LS86?

The maximum sensing distance for the Omron E3Z-LS86 is 200mm.

Can this sensor detect objects of different colors?

Yes, the E3Z-LS86 uses triangulation and background suppression, making it less sensitive to object color and more focused on distance, allowing it to detect objects of various colors reliably.

What type of output signal does the E3Z-LS86 provide?

It provides a PNP output signal, which is a common type in industrial automation.

Is the E3Z-LS86 suitable for outdoor use?

With an IP67 rating, it is protected against dust and temporary immersion in water, making it suitable for many industrial environments, but not continuous outdoor exposure without additional protection.

How do I adjust the sensing range?

The sensing range is adjusted manually using the adjustment dial located on the sensor housing.

What is the response time?

The response time of the Omron E3Z-LS86 is 1ms.

What are the operating temperature limits?

The sensor can operate in ambient temperatures ranging from -25°C to +55°C.

Troubleshooting

Sensor not detecting objects.

Verify power supply connections (10-30V DC). Ensure the object is within the 20-200mm sensing range. Adjust the sensitivity dial. Check if the output is correctly wired to the control system.

Sensor detects background objects.

Adjust the sensitivity dial to a lower setting or re-position the sensor to ensure the background is outside the optimal sensing zone. Ensure the background is not highly reflective and directly behind the target.

Intermittent detection.

Check for obstructions or dirt on the optical lens. Ensure stable power supply and secure wiring connections. Verify that the target object's reflectivity is consistent.

Sensor not powering on.

Confirm the DC power supply is within the specified 10-30V range and correctly connected with proper polarity. Check the power supply source for functionality.

Pros and Cons

Pros

  • Reliable detection of objects against complex backgrounds.
  • Flexible sensing range accommodates diverse application setups.
  • Robust construction suitable for industrial environments.
  • Quick response time for high-speed automation.
  • Easy integration with standard industrial control systems.

Cons

  • May struggle with extremely glossy or mirrored surfaces directly behind the target.
  • Adjustment requires manual setting, which can be time-consuming in frequent changeovers.
  • Limited sensing distance compared to some long-range sensors.
  • Requires a stable DC power supply (10-30V DC).

Setup, Compatibility & Care

Setup:

  1. Mount the sensor securely using its flange mount, ensuring the target object will pass through the sensing beam.
  2. Connect the sensor using the M8 4-pin connector to a compatible DC power supply (10-30V DC) and the control system input.
  3. Adjust the sensing distance manually using the adjustment dial on the sensor to achieve reliable detection of the target object while ignoring the background.

Compatibility:

  • Power Supply: Requires a DC power supply within the 10-30V range.
  • Output: Compatible with control systems accepting a PNP output signal.
  • Environment: Suitable for environments with temperatures ranging from -25°C to 55°C and protection against dust and water (IP67).

Care:

  • Keep the optical surfaces clean. Use a soft, dry cloth or a slightly damp cloth if necessary. Avoid abrasive cleaners.
  • Ensure connections are secure to prevent electrical issues.
  • Periodically check the sensing range adjustment, especially if environmental conditions change.
