Omron E3FA-TN11 2M Photoelectric Sensor

Omron E3FA-TN11 2M  Photoelectric Sensor

The Omron E3FA-TN11 Photoelectric Sensor is a cylindrical photoelectric sensor from the E3FA series, designed for precise detection and reliable performance in various industrial applications. This sensor employs a through-beam sensing method and provides a sensing distance of up to 20 meters, making it ideal for long-range object detection.

The red LED light source (wavelength: 624 nm) ensures accurate detection of objects. With both Light-ON and Dark-ON modes available, the sensor can be configured to match different operational needs, offering flexibility in various use cases. The sensor utilizes an NPN open collector output, with a maximum load current of 100 mA and a maximum applied voltage of 30 VDC.

Designed for durability, the Omron E3FA-TN11 Photoelectric Sensor includes short-circuit protection, reverse polarity protection (both output and power supply), and is built to withstand harsh environments. It has a response time of 0.5 ms and features a single-turn sensitivity adjustment to fine-tune detection performance.

The sensor operates in a wide ambient temperature range of -25°C to 55°C, and is resistant to ambient illuminance with tolerance for up to 10,000 lx of sunlight and 3,000 lx of incandescent light. With an IP67 protection rating, the sensor is highly resistant to dust and water, making it suitable for industrial and outdoor environments.

The pre-wired model comes with a 2-meter cable, simplifying integration and installation in industrial systems.
