Optical sensors such as photointerrupters are used in a variety of applications to detect objects, detect motion, or measure position. The OPB885Z slot type, transistor output photointerrupter is a popular choice for many industrial, automotive, and consumer applications.

The OPB885Z photointerrupter consists of an emitter LED and a phototransistor integrated in a two-part molded plastic housing. The sensing element is an infrared emitting diode positioned to shine light onto a photodetector. The sensing slot between the LED and photodetector creates a break in the light signal when an object enters the sensing slot and cuts off the light. The output of the photodetector is then used to detect the presence of the object.

The OPB885Z photointerrupter offers a number of features, including low power consumption, long-life reliability, and low cost. The device has a high-sensitivity phot detector with a small 2mm sensing slot that can detect objects as small as 0.3mm. It also features a reverse biased emitter diode, which increases the stability of the device.

The OPB885Z photointerrupter operates in two modes: normal-on and normal-off. In normal-on mode, the photodetector is in the "on" state when there is no object in the sensing slot and the incoming light is blocked. When an object enters the sensing slot, the photodetector turns "off." In normal-off mode, the photodetector is "off" when there is no object in the sensing slot and the incoming light is not blocked. When an object enters the sensing slot, the photodetector turns "on."

The OPB885Z photointerrupter is ideal for a wide range of applications that require precise positioning or sensing of objects. It is also used to detect the presence or absence of objects in a slot and can be used for motion detection, limit sensing, and proximity sensing. A common application is to detect the presence of a coin or bill in a slot for payment acceptance.

In addition to its small size and low cost, the OPB885Z photointerrupter offers a high level of reliability and durability. The device is rated for a minimum of one million cycles and its wiring is resistant to water and shock. This makes the OPB885Z ideal for applications in harsh environments.

The OPB885Z photointerrupter is a versatile device that is ideal for a wide range of applications. It is an ideal choice for applications requiring precise positioning or sensing of objects, motion detection, limit sensing, and proximity sensing. The device is also reliable and durable, making it suitable for use in harsh environments.
