Optical sensors, also known as photointerrupters, are devices that use optical technology to detect the presence and/or absence of an object within an environment. The OPB380N11Z is a slot type optical sensor that features a transistor output. It can be used in a variety of applications, and is especially suited for applications wherein low power consumption is desired.

The OPB380N11Z measures 3.2mm x 11mm in size; it is composed of a sealed, black plastic housing containing a slot phototransistor and a back-mounted infrared emitter. The phototransistor is an NPN compound device, and the infrared emitter produces a modulated signal when activated. The OPB380N11Z operates on 3V (min.) to 24V (max.) power supply.

In order to detect the presence and/or absence of an object, the OPB380N11Z utilizes a slot type design, wherein an object located between the emitter and detector can block the detecting beam. The presence of the object will cause the output to change from "Off" to "On". When the object is removed, the signal returns to "Off" and the circuit is deactivated. The OPB380N11Z can operate with a maximum switching frequency of 20 kHz.

The OPB380N11Z can be used in a wide variety of applications where optical sensing is desired. Typical applications include object location, position sensing, and proximity sensing. In each instance, an external circuit is necessary to control the sensing and output of the OPB380N11Z. When externally activated, the OPB380N11Z can directly drive a load, such as a relay, to control the desired action.

The working principle of the OPB380N11Z optical sensor is straightforward. The emitter is activated and the phototransistor in the detector will be turned "On" when an object is detected. When the presence of the object is removed, the phototransistor will automatically switch "Off". This change in state is detected by the external circuitry and is then used to activate the desired action.

The OPB380N11Z Optical Sensor is an excellent choice for applications requiring a small, compact design and low power consumption. With its slot-type design and transistor output, the OPB380N11Z can easily be integrated into a variety of applications. Its small size and low power consumption make it an ideal choice for applications that require a robust and reliable sensing solution.
