Optical Sensors - Photointerrupters - Slot Type - Logic Output

Photointerrupters are types of optical sensors that detect the presence or absence of objects in a predetermined area. The EE-SPX401 is a slot-type photointerrupter with a built-in logic output. It is designed to detect the presence of objects in a working area, for use in bi-directional sensing applications.

Working Principle

The EE-SPX401 consists of an infrared LED and an NPN phototransistor encased within a plastic package. The gap between the LED and phototransistor works as a slot window. The product works on the principle of optical isolation and is employed in bi-directional object detection applications. When the object passes into the gap, the light is interrupted and the photonumber decreases, inducing a current flow in the phototransistor thus triggering the logic output. This logic output can be used to signal the presence or the absence of the object.

Advantages

The EE-SPX401 has many advantages over existing photointerrupter options. It offers a simple and straightforward interface which is easy to use, and is highly reliable in operation. The built-in logic output eliminates the need for an external interface or circuit, eliminating the risk of interference. The sensor is also highly sensitive, and can accurately detect objects in a wide range of positions and gap distances. In addition, it is small and compact in size, making it suitable for use in tight spaces. It has a wide operating voltage range from 2.7 to 5.5V and can be safely used in a variety of projects. It also has a high temperature range of -40 to +50°C (-40 to +122°F) which allows it to operate in both cold and hot climates. Lastly, it can operate at a frequency of up to 100 kHz, providing fast and accurate detection.

Applications

The EE-SPX401 can be used in a variety of different applications. Its primary use is to detect the presence or absence of objects in a bi-directional sensing application. This can be used in a variety of areas, such as doorways, elevators, conveyor belts, and machine automation. In addition, the EE-SPX401 can be used in a variety of other applications such as motion detection, product counting, and pick-and-place operations. The wide temperature range and high frequency operation make it suitable for use in almost any environment. Overall, the EE-SPX401 is an ideal solution for any bi-directional object detection application. With its high accuracy and reliability, it is sure to be a valuable addition to any project.
