The EZ-11-J is a slot type logic output photointerrupter composed of an LED emitter and a NPN phototransistor as optical components. When objects obstruct the optical signal path, the output state of the EZ-11-J will change. This device has a wide range of application fields, and it’s working principle has broadened the fields of optical sensors.

The most common use of the EZ-11-J is in objects detection for car assembly lines, robotics, automated door locks, vending machines, and other industrial applications. Due to the structural design of the EZ-11-J, it can detect objects which pass through its optical path without making contact with it. This makes it ideal for applications where continuous detection is required. As a result, the EZ-11-J can be used for presence and height detection in manufacturing lines, object recognition, moving target detection, and edge detection.

The working principle of the EZ-11-J is quite simple. The device consists of an infrared emitter and an NPN phototransistor, with a slot between them. When an object passes through the slot, it blocks the infrared light emitted from the emitter, resulting in a decrease in the level of light that reaches the phototransistor. The phototransistor then produces a corresponding electrical signal by changing its conductivity. This signal is then used by the user to control some aspect of the operation, either directly or through other circuits.

The EZ-11-J, due to its small size, low power requirements, and the fact that it does not require a dedicated power source, is also becoming more popular for use in smaller consumer level applications, such as mobile phones, personal digital assistants, and other such applications. It can also be used in conjunction with other sensors, such as pressure or temperature sensors, to detect the presence of objects in a specific environment, or the amount of force applied to an object.

The EZ-11-J has revolutionized the fields of optical sensors, photointerrupters, and slot-type logic outputs by making them applicable to a much wider range of application fields. Its small size, low power requirements, and capability to detect objects without making contact with them have made it suitable for a wide range of applications. Its ability to detect objects without needing an external power source also makes it highly attractive for consumer-level applications. Nowadays, it is used widely in many industrial and consumer-level applications.
