Optical Sensors are devices used to detect the presence or absence of an object. They are commonly used in the automotive, industrial and medical industries. Photointerrupters are a type of optical sensor that uses a light source to detect when an object is passing through a defined area or slot. The EE-SX3157-P1 is a slot type, logic output Photointerrupter that is commonly used in industrial, commercial and medical applications. This article will cover the application field and working principle of the EE-SX3157-P1.

The EE-SX3157-P1 is a reflective type Photointerrupter which is designed to detect the presence of an object passing through the slot. It is housed in a TO-5, 6-pin package with a 25mm long, 2.54mm width slot. It is available with either a transparent or dark-colored slot. This type of Photointerrupter is commonly used in industrial, commercial and medical applications such as counting, position sensing, home appliances, security systems, and medical equipment. The EE-SX3157-P1 operates with an operating voltage of 5V DC and has an insulation resistance of 1000MΩ or higher.

The working principle of the EE-SX3157-P1 is based on the use of an infrared light source and a Photodiode to detect objects. The infrared light source is made up of a light-emitting diode (LED) and a photodiode which is situated opposite the LED and connected to the active collector. When an object passes through the slot, the photodiode is blocked by the object which in turn blocks the light being sent from the LED. This change in the amount of light being blocked is detected by the photodiode resulting in a change in voltage across the photodiode. This change in voltage is then converted to a logic output by an internal circuit and the output is then transmitted to the active collector. This logic output can be used by an external circuit to trigger certain events or to measure the speed of the object being detected.

In conclusion, the EE-SX3157-P1 is a slot type, logic output Photointerrupter that is commonly used in industrial, commercial and medical applications. It uses an infrared light source and a photodiode to detect objects that are passing through a 25mm long, 2.54mm width slot. When an object is detected, the change in voltage is converted into a logic output and the output is then transmitted to the active collector. The EE-SX3157-P1 is a reliable and cost-effective way to detect the presence of an object and can be used in a variety of applications.
