Product Overview
The Omron E39-R7 is an 84 mm round acrylic reflector from the E39-series 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.
The reflector face is 84 mm in diameter and 7.4 mm thick, weighing 32 g. A single M4 mounting hole in the centre seats a vibration-resistant bolt.
Storage -25 to +65 degC; operating -10 to +55 degC. Key specs: Reflector Type Round, acrylic, micro-prism; Outer Diameter 84 mm; Thickness 7.4 mm; Mounting Hole 1 x M4 centre hole; Adhesive Backing None (bolt-mount only); Compatible Sensors E3F2, E3FA, E3Z, E3JM retro-reflective heads; Protection IP67 / IP69K; Operating Temperature -10 to +55 degC operating, -25 to +65 degC storage.
Key Features
- E39-series 84 mm round acrylic reflector
- IP67 and IP69K rated for high-pressure washdown panels
- Single M4 mounting hole, 32 g, no self-adhesive backing
- Pairs with E3F2 / E3FA / E3Z / E3JM retro-reflective sensors
- SKU: E39-R7
- Series: Omron E39-series reflector accessory
Best-Fit Applications
- Long-distance bottle detection on a beverage line where the IP69K face survives daily clean-in-place washdown at 80 degC
- ASRS bay-clearance check on a warehouse crane where the 84 mm face returns a strong signal at the 4 m sensing distance
- Spare replacement on a conveyor where the original small reflector kept missing clear PET bottles and the E39-R7 fixed the false-negatives
Buying Checklist
- Pick the E39-R7 for an 84 mm round IP69K reflector on a washdown line where a smaller reflector keeps missing clear targets.
- Pick the E39-R1S instead when the application needs a 60 mm square reflector on the same E39 platform.
- Pick the E39-L98 instead when the panel needs a protective mounting bracket for an E3Z sensor, not a reflector.

FAQ for E39-R7
What sensors does the E39-R7 work with?
Most Omron retro-reflective photoelectric sensors, including the cylindrical E3F2 family and the compact E3FA, E3Z and E3JM heads. The 84 mm face gives a strong return signal, so it is a good match for clear-object and long-range applications.
Can the E39-R7 survive high-pressure washdown?
Yes. The reflector carries IP67 plus IP69K ratings, which covers 80 degC, 80 to 100 bar high-pressure hot-water jets from any angle. Food, beverage and pharmaceutical panels are the main use cases.
Does the E39-R7 need a separate bracket?
Not usually. The single M4 centre hole takes a bolt directly through the back of the reflector. For adjustable mounting, fit the reflector on an E39-L98 sensor mounting bracket or a standard 84 mm sensor bracket.
How big a target can the E39-R7 detect?
Detection depends on the sensor. As a rule, the E39-R7 extends the sensing distance of a matched E3F2 or E3Z sensor by 30 to 50 percent compared with the smaller E39-R1S reflector, because the larger face returns more light.
Does the E39-R7 work with red-light sensors?
Yes. The micro-prism face reflects both red LED and infrared wavelengths, so the reflector matches every Omron retro-reflective sensor in the E3F2, E3FA, E3Z and E3JM families regardless of the light source colour.
