Optical sensors convert data from the physical world into signals which can be read by instrumentation and are used to measure a variety of environmental conditions. They are also used to detect the presence or absence of objects and can be used in machine vision systems for various industry applications. The E3FA-DN21 is a type of photoelectric optical sensor, suitable for industrial applications. It has a wide range of sensing distances and work with both non-magnetic heavy-duty enclosed sensors and micro-sensors.

The E3FA-DN working principle is based on the photoelectric effect. When the diffusely or sharply reflecting object enters the inner side of the light receiving lens, the light intensity of the optical receiver is changed, and is converted by the light intensity receiving element into a voltage signal. The voltage differences between the optical receiver and the reference voltage generate a logic output. This logic output signal is sent to the various controllers to determine the action to be performed.

The E3FA-DN21 is a photoelectric sensor with dual sensing ranges for heavy-duty enclosed and micro-sensors, making it ideal for a wide range of industrial applications. The sensing distance of this unit ranges from 4mm to 50mm, depending on the type of reflector used and environmental environment. It is equipped with 6 in1 multi-level interface, including switching power supply, DC power supply, NPN (NO) / PNP (NC) output, relay output, AC / DC 12/24V output and Pulse Output. This versatility makes it suitable for a wide range of applications.

The E3FA-DN21 is a durable and reliable double-channel photoelectric sensor, designed for industrial applications. It is designed to deal with different application environments, and can be used with a variety of reflectors to achieve different sensing distances. It is easy to install, with its 6 in1 multi-level interface providing both power and communication outputs. With its wide sensing distance, the E3FA-DN21 is an ideal choice for industrial applications.
