Product Overview

The E3Z-LS61 is engineered for applications where standard diffuse sensing is insufficient due to distance, target size, or background interference. Laser through-beam architecture improves detection reliability and edge definition, making it suitable for high-speed production environments. It is frequently used in packaging, material handling, and precision assembly systems where false triggers can affect cycle consistency and product quality.

  • SKU: E3Z-LS61

FAQ for E3Z-LS61

What is background suppression?
Background suppression allows the sensor to detect objects while ignoring backgrounds beyond the set distance. The sensor only responds to objects within the configured sensing range.
Is the laser safe?
Yes, Class 1 laser is safe under all normal operating conditions per IEC 60825-1. No special safety measures required.
How do I adjust the sensing distance?
Use the sensitivity adjustment potentiometer while monitoring the operation LED. Set the distance with your target at the desired detection point.
Can this detect small objects?
Yes, the focused laser beam enables detection of small objects down to 0.1mm with precise positioning.
