Product Description P/N: E3S-R36
Description
The Omron E3S-R36 Photoelectric Sensor is a square-type, retro-reflective photoelectric sensor with an M.S.R. (Mirror Surface Rejection) function designed for precise object detection in industrial automation systems. Operating on 10–30 VDC, it uses a red LED light source and provides a PNP open-collector output, supporting both Light-ON and Dark-ON modes for versatile application control.

Information About E3S-R36
The E3S-R36 is part of Omron’s E3S Series, engineered for reliable detection of opaque objects and reflective materials. When used with the E39-R1 reflector, it achieves a sensing distance of 0.1 to 1 meter, maintaining accuracy even on highly reflective or transparent surfaces due to its advanced M.S.R. optical filtering. The sensor includes short-circuit and reverse-polarity protection, ensuring long-term durability in demanding industrial environments. Designed with a compact, IP67-rated housing, it withstands exposure to dust, vibration, and moisture. Its integrated red and green status indicators simplify setup and troubleshooting, while the M12 connector allows for quick installation and maintenance.
Key Features:
- Retro-Reflective Sensing: Detects objects using a built-in M.S.R. (Mirror Surface Rejection) function for reliable operation near reflective surfaces.
- Wide Sensing Range: Detects objects at distances from 0.1 to 1 m when paired with the E39-R1 reflector.
- Fast Response Time: Operate or reset response within 1 ms for high-speed detection.
- Selectable Modes: Light-ON or Dark-ON operation selectable for flexible control integration.
- Robust Protection: Includes short-circuit and reverse-polarity protection circuits.
- High Durability: IP67-rated PBT housing resists dust, vibration, and water ingress.
- Easy Installation: M12 connector design for fast connection and maintenance.
- Status Indicators: Red LED (light indicator) and green LED (stability indicator) for quick visual feedback.
The E3S-R36 delivers the reliability and precision required for automated object detection in industrial sensing applications.
