The BRQM400-DDTA is likely a model of a photoelectric sensor used in industrial automation and control systems. Here’s a brief overview:

• BRQM400-DDTA is a photoelectric sensor that detects the presence or absence of objects using light (usually infrared or visible light).

• The model might feature through-beam, diffuse, or retro-reflective sensing modes, offering versatility in detecting objects at varying distances.

• DDTA could indicate specific output types (e.g., NPN or PNP transistors) or an integrated time delay feature for specific applications.

• Commonly used in conveyor systems, material handling, safety gates, and other industrial automation tasks to ensure accurate object detection and enhance system efficiency.
