Optical sensors are used in a wide variety of applications, including those related to safety, motion control, and environmental monitoring. The EE-SX471 slot type Logic Output Photointerrupter is designed for applications when a beam is used to detect objects. This photointerrupter features an optimized response time and allows for a maximum on/off switching speed of 100kHz. The EE-SX471 consists of a pair of infrared emitting diodes and a phototransistor which is used to detect the presence of an object.

The EE-SX471 utilizes a slot-type detection design which means that when an object passes through the sensing slot, the infrared beam is broken causing the output voltage to drop from high to low or vice versa. The output transistor of the photointerrupter is an open-collector NPN transistor which is designed to function in either a normally-open or a normally-closed configuration. The output voltage is inversely proportional to the input current, i.e., if the input current is raised, the output voltage will drop. The output voltage is also dependent on the ambient light conditions, i.e., if the ambient light increases, the output voltage will drop.

The EE-SX471 uses a reverse sensing configuration, where the output voltage is high when the beam is broken. This means that the device will detect the presence of an object or a gap correctly regardless of the background light conditions. The EE-SX471 is also RoHS compliant and is available in a variety of packages. The device is rated for an operating temperature range from -25°C to 70°C.

The EE-SX471 is well suited for a wide variety of applications, such as object detection, presence detection, position sensing, and motion detection. The device can be used in industrial automation applications as well as in consumer products. EE-SX471 also has a variety of applications in security systems, such as sensing the presence of a person or object.

The logic output of the EE-SX471 is compatible with most microcontrollers and logic ICs. The device features low power consumption and can operate at a supply voltage from 2.7V to 20V. The device also features a built-in pull-up resistor so no external components are needed to use the device. The built-in pull-up resistor ensures that the output voltage is always high when there is no beam broken.

The EE-SX471 is a reliable and robust slot-type photointerrupter which is suitable for a wide variety of applications. The device features an optimized response time and is capable of operating at a maximum on/off switching speed of 100kHz. The device is also RoHS compliant and features a built-in pull-up resistor. The wide supply voltage range and low power consumption make the EE-SX471 ideal for applications related to object detection, position sensing, and motion detection.
