Product Overview
The Omron E3Z-D82 is the M8-connector variant in the E3Z-D8x long-range (1 m) diffuse-reflective photoelectric family, with PNP open-collector output and a 660 nm red LED emitter. 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.
The 1 m sensing distance (rated with a 300 × 300 mm white paper target at 100 × 100 mm to 1 m working range) covers most conveyor-rail, parts-present-at-station, and bin-detection jobs without needing a separate retro-reflective target. The visible-red spot is the key to fast commissioning — you point, see the red dot on the target, and confirm aim before locking down the bracket.
Then turn it up slowly until the indicator turns ON reliably with the target present, then add a quarter turn of headroom.
Key Features
- 1 ms response time
- Current consumption 30 mA max
- PNP open-collector output, 100 mA max switching current
- Operating voltage 12 to 24 VDC ±10 %
- SKU: E3Z-D82
- Series: E3Z Compact Photoelectric Sensor with Built-in Amplifier
- Voltage: 24 VDC
Best-Fit Applications
- Pallet stack-height monitoring at the exit of a stretch-wrap station — E3Z-D82 detects the top of the load
- Carton-presence detection on a roller conveyor entry — sensor 0.7 m above conveyor, brown cardboard carton is the reflective target.
- Bin-fill level verification on a vibratory feeder bowl — sensor mounted inside the feeder tooling, target = level of parts.
Buying Checklist
- Pick E3Z-D87 for an NPN sinking-output M8-connector variant
- Pick E3Z-D81 2M for a 100 mm short-range PNP pre-wired sensor
- Pick E3Z-D82 2M for the same sensor with a pre-wired 2 m cable

FAQ for E3Z-D82
What's the difference between E3Z-D82 and E3Z-D86?
Functionally, none — the E3Z-D82 and E3Z-D86 are the same 1 m diffuse-reflective PNP M8-connector sensor; the D82 is the global catalog number (Omron Industrial Automation) and the D86 is the European-region catalog number suffix (-OMI / E3Z-D86 2M OMI). Both use the same red LED emitter, both have the same 100 mA PNP output, both have the same 1 ms response, both use the same M8 4-pin connector with IEC 60947-5-2 pinout.
What cable do I use with the E3Z-D82 M8 connector?
Use the Omron XS3F-M series M8 4-pin female-to-pigtail cable. The standard PVC variant is XS3F-M421-402-A (2 m PVC, oil-resistant, 4-conductor; wire colors brown = +V, white = pin 2 unused, blue = 0 V, black = OUTPUT per IEC 60947-5-2). For cable carriers or moving-machine applications where the cable flexes continuously, use XS3F-M422-402-A (2 m PUR, oil-resistant, robotic-grade) instead. For right-angle exit where space is tight, use the L-angle variants XS3F-M421-404-A (4 m PVC) or XS3F-M422-404-A (4 m PUR).
Why is the red LED spot visible on the target?
The E3Z-D82 uses a 660 nm visible red LED emitter instead of infrared — the red dot is intentional, not a side effect.
How does the E3Z-D82 fail on shiny or transparent targets?
Diffuse-reflective sensors detect a target when light from the emitter reflects off the target's surface back into the receiver. On shiny surfaces like polished stainless steel, mirror-finish aluminum, or wet/glass surfaces, the light specularly reflects at the same angle as the incident beam — most of the light bounces away from the receiver, and the sensor does not see the target reliably.
