### 2.5 Low Power Consumption
Designed with energy efficiency in mind, the OPB375N51 sensors consume very low power. This is beneficial for battery - powered applications, as it helps to extend the battery life and reduce the overall energy consumption of the system.
## 3. Technical Specifications
### 3.1 Optical Characteristics
- **Emitter Wavelength**: The sensors typically use an infrared (IR) emitter with a wavelength in the range of 850 - 940 nm. This wavelength is well - suited for many applications as it is less affected by ambient light and can penetrate through certain materials.
- **Detector Sensitivity**: The photodetector has a high sensitivity, with a typical responsivity of [X] A/W at the specified wavelength. This ensures accurate detection of the emitted light.
### 3.2 Electrical Characteristics
- **Supply Voltage**: The sensors can operate within a supply voltage range of [X] V to [Y] V, providing flexibility in power supply design.
- **Output Signal**: They provide a digital or analog output signal, depending on the specific model. The output signal can be easily interfaced with microcontrollers, PLCs, or other control systems.
- **Quiescent Current**: The quiescent current is very low, typically in the range of [X] μA, which contributes to the low power consumption of the sensors.
### 3.3 Mechanical Characteristics
- **Package Type**: The OPB375N51 sensors are available in a variety of package types, such as surface - mount packages (e.g., SMD) and through - hole packages. This allows for easy integration into different printed circuit board (PCB) designs.
- **Dimensions**: The compact dimensions of the sensors make them suitable for a wide range of applications. For example, the length may be [X] mm, the width [Y] mm, and the height [Z] mm.
