The LA-511 is a logic output type slot type photointerrupter optical sensor from Omron. It is comprised of a light-emitting element and a light-sensitive element positioned on opposite sides with a slot between them. When an object passes between the two elements, the light beam is interrupted and the output signal from the sensor changes. As the object moves out of the light beam again, the output signal from the sensor returns to its original voltage level.

The LA-511 is designed for applications requiring high accuracy or a wide light-interruption range. It is suitable for use in a variety of different machine and electronic applications such as detecting the presence and absence of parts or monitoring objects during production processes. Its features include a wide-angle detection, compact size, high sensitivity, and a logic output. This makes it suitable for many automated applications.

Working Principle

The LA-511 operates using a basic working principle that involves passing a light source from one side to the other. The optical sensor is specifically designed for detecting thin objects or objects with small variations in thickness. When an object enters the light beam, the light source on one side is blocked, preventing the light from reaching the opposite side. This causes the output signal to change. As soon as the object passes out of the light beam, the output signal returns to its normal voltage level.

The output signal of the LA-511 can be configured for either NPN or PNP outputs. The logic level of the output signal changes depending on the presence or absence of an object detection. When an object blocks the light beam, the output signal switches to one state (high or low), and when the object passes out of the light beam, the output switches to the opposite state.

Features and Benefits

The main features and benefits of the LA-511 include:

• Long sensing distance: up to 12mm (0.47 in.)
• Compact size: 8mm (0.31 in.) x 15mm (0.59 in.)
• High reliability: up to 1 million operations
• Fast response time: 10 microseconds
• Wide detection angle: up to +-60 degrees

The LA-511 is an ideal optical sensor for high-precision and high-reliability applications such as automated production line processes and other applications where accurate and reliable detection of objects is essential.

Applications

The LA-511 is used in a variety of different applications that require accurate and reliable detection of objects. Some common applications include:

• Automotive sensing
• Robotics
• Packaging machines
• Container handling
• Quality inspection
• Material handling
