Reliable Through-Beam Sensing with NPN Output
The E3T-FT12 uses a through-beam sensing method. This means it has a separate emitter and receiver. This method is highly reliable for detecting objects. It is not easily affected by the color or surface of the object being detected. The red LED light source is easy to see, which helps with alignment.
This model provides a Dark-ON NPN output. The output turns on when the red light beam between the emitter and receiver is blocked. The NPN output is common in many control systems, making this sensor easy to integrate. With a 500 mm sensing distance, this sensor is versatile for a wide range of tasks.
Built-in Amplifier for Simplified Installation
That’s why the Omron E3T-FT12 sensor has a built-in amplifier. This feature simplifies wiring and installation. You don’t need a separate amplifier unit, which saves space and reduces costs.
The sensor comes with a pre-wired 2m cable. This makes connecting to your power supply and control system straightforward. The simple setup means you can get your production line running faster. The built-in design ensures a clean and professional installation every time.
Robust Red LED Light Source for Stable Detection
The E3T-FT12 uses a bright red LED as its light source. This red light provides a clear, visible spot that makes setup and alignment easy. You can quickly see if the sensor is positioned correctly.
This product is also designed to work well even with high ambient light. Pulse synchronization technology helps prevent interference from other light sources. The sensor’s lens and case are made from durable denatured polyarylate, and it has an IP67 rating. This means it is protected from dust and water, ensuring long-lasting performance in industrial environments.
