The EE-SPX742 is a slot-type photointerrupter logic output optical sensor. It is reliable, cost effective, and easy to use. It is used in a wide variety of applications, from industrial to consumer products and appliances.

The EE-SPX742 is an optical sensor with an active area of 4.2mm in the slot type. The device consists of an infrared emitting diode (LED) and a photosensitive transistor. A light beam is emitted from the LED and enters the detection area in a slot. When an object partially blocks the slot, a portion of light is blocked and a voltage drop is detected at the phototransistor. Output can be read in two directions, upstream or downstream.

EE-SPX742 is most commonly used in the automotive and consumer electronics markets, as well as other industries requiring accurate and reliable optical sensing. In automotive applications, this device is used for monitoring interior lighting, doors, and seat occupancy detection. In consumer electronics, EE-SPX742 can be used for game consoles, TV remote control, motion detection, etc. In industrial applications, it is used for conveyor belt monitoring, detection of paper jams in copiers and printers, and motion detection.

The primary working principle of the device is based on the interruption of light from the LED source by an object. When the light is visible, the phototransistor output voltage remains high. When the light is blocked, the output voltage decreases resulting in a numerical value that can be used to control the target. The output is highly reliable and repeatable as it is not dependent on any environmental variables like temperature or humidity.

The device can be programmed to work in two modes: latching and non-latching. In latching mode, when the light is blocked by an object, the output voltage remains low until reset manually or via program. In non-latching mode, when the light is blocked, the output is only low for a short period of time and then returns to the initial state. This is useful for systems that require a longer period of detection.

The EE-SPX742 is a useful and versatile optical sensor with multiple applications. With its simple design, reliable output, and cost-effective construction, it is an excellent choice for many applications. It is ideal for use in automotive, consumer electronics, and industrial automation applications that require accurate sensing and control.
