Product Overview

The Omron E3Z-LR86 is a compact retro-reflective photoelectric sensor with a visible red laser Class 1 source for where LED retro-reflective sensors are not precise enough. It is manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.

M8 4-pin connector 12-24 VDC ±10 % supply, 30 mA current draw PNP open-collector output, 100 mA at 26.4 VDC max. 12-24 VDC ±10 % supply, 30 mA current draw

PNP open-collector output, 100 mA at 26.4 VDC max. 12-24 VDC ±10 % supply, 30 mA current draw

For transparent objects the E3Z-B PET-bottle sensor is the right pick instead.

  • 15 m sensing distance with E39-R1 reflector (5 mm spot at 3 m)
  • M8 4-pin connector
  • SKU: E3Z-LR86
  • Series: E3Z-LR compact laser retro-reflective sensor
  • Voltage: 12-24 VDC

Best-Fit Applications

  • Long-distance trigger for boxes or totes on a warehouse conveyor
  • Shiny-label and foil-wrap detection on a cosmetic or food line
  • Small-part presence check on an electronics pick-and-place infeed

Buying Checklist

  • Choose E3Z-LL86 for BGS laser detection at 20-300 mm range.
  • Choose E3Z-LR86 for laser retro with MSR, PNP, and M8 connector.
  • Choose E3Z-LR81 2M for the same sensor with a pre-wired 2 m cable.

FAQ for E3Z-LR86

What is the difference between E3Z-LR86 and E3Z-R86?
Both are compact MSR retro-reflective sensors with PNP and M8 connector. The E3Z-LR86 uses a laser source for a 5 mm spot at 3 m and a 15 m range; the E3Z-R86 uses a red LED for a 4 m range. Pick the LR86 for small parts, shiny labels, or long distances where the laser spot is needed; pick the R86 for general-purpose retro at a lower price.
What reflector does the E3Z-LR86 need?
Use the standard E39-R1 reflector for a 15 m range. For a smaller 200 mm spot at half the range, use the E39-R2 or E39-R6 reflector. Allow at least 100 mm between the sensor and the reflector for stable detection, and clean the reflector face on the same schedule as the line belt to avoid false drops from contamination.
Why does the E3Z-LR86 use M.S.R. optics?
M.S.R. (Mirror-Surface Rejection) is an optical filter that ignores the polarised reflection from shiny surfaces such as foil labels, polished metal, or gloss cartons. Without it, a shiny target reflects the laser back to the sensor and is detected as a fault (light received through the polarised filter). With M.S.R., only the diffuse signal from the actual target reaches the detector, so shiny-label applications detect reliably.
