Photoelectric sensors, also known as industrial vision sensors or photoelectric switches, are used to detect the presence, absence, or color of objects. ET4-P3215 is a photoelectric sensor introduced by Pansonic. It is a 2-point type photoelectric sensor with a long sensing distance of up to 3m. It has high immunity to ambient light conditions with its immunity rating up to 10,000LX. This product is suitable for wire connection wiring and providing reflective sensing applications.

The main application field of this model includes vending machines, packaging, controlling the entrance and exit of conveyor stops, auto doors and safety guards, etc. Its sensor head could be used as a surge protector to protect it from possible damage caused by lightning and power spikes. This model is highly reliable and cost-effective since it is a dust-resistant and water-resistant photoelectric sensor.

The working principle of ET4-P3215 is a simple one. It uses infrared light, produced by the LED at the sensor head, to monitor the target object. When the light beam is obstructed by an object, the built-in photocell detects the change in luminosity and signals the output terminal. The amount of light that passes through the laser beam determines the sensitivity of the sensor. It has a direct beam distance of up to 3m and its incident light type can detect absence/nearness with an object. It also provides visible light sensing functions such as colour detection and counting.

The advantages of ET4-P3215 model are numerous. It has a long sensing distance up to 3m, which allows much space for application and makes it suitable for large object detection. It also has superior immunity against changes in ambient lighting, as the immunity rating is up to 10000LX, ensuring accuracy in various environments. Moreover, it has multiple power supply options - AC/DC, DC/AC, AC only, and voltage tolerant power supply that adds to its versatility. Its shield cover and small sensor head further provide a compact design for space-saving installation.

To summarize, ET4-P3215 is a photoelectric sensor designed for industrial applications and includes a variety of applications such as vending machines, packaging, controlling conveyor stops, and automatic doors. Its working principle utilizes infrared light to detect the presence of objects in a long sensing distance of up to 3m. It also has superior immunity against changes in lighting conditions, multiple power supply options, and a small sensor head for space-saving installation. All these factors make ET4-P3215 a highly efficient and reliable photoelectric sensor for industrial environments.
