Proximity sensors are devices designed to detect the presence of an object or material without causing any physical contact. Whether a hand pushes a button or a distance monitor from a distance of several meters, the switch will respond accordingly. Proximity sensors detect the presence or absence of objects using electromagnetic fields, light, and sound. The E2J-A04 is a single-beam, photon-counting type proximity sensor.

The E2J-A04 is a single-beam proximity sensor, which usually means that it can only detect objects within a certain distance or area. Its sensing distance is adjustable from 10mm to 2,000mm, and its field of view is rectangular. Its output mode can be configured as NPN or PNP open-collector type, the response time is adjustable according to user\'s request. E2J-A04 features a human body presence detection accuracy of up to ±2 mm.

The working principle of the E2J-A04 is photon-counting. It uses sensing head emitting an infrared laser light source to detect objects. When the imaginary line that is perpendicularly in contact with the light receiver hits an object, the reflected light is detected. The sensor will then convert the light intensity into a voltage, which is then transmitted to its output. The key is to accurately count the photons that are reflected so that the object can be detected.

The E2J-A04 is commonly used for range measurement and safety applications. It can be used to detect objects, measure distances, detect movement, and detect objects within a certain range. It is also used for automation applications such as robotic arms and pick-and-place systems. It is highly reliable, making it a popular choice in industries like automotive, medical, and aerospace.

The E2J-A04 is designed to be user friendly and intuitive, making it easy to set up and use. It is also highly configurable, allowing users to adjust the sensing parameters, adjust the response time, and configure the output mode. The sensor is also equipped with a monitoring LED that allows users to quickly check the presence or absence of objects.

Overall, the E2J-A04 is a reliable and user friendly proximity sensor that can be used for a variety of applications. It is highly configurable, making it easy to set up and use, and its sensing accuracy makes it a popular choice in a variety of industries.
