EE-SX671R

Optical Sensors involve the use of infrared light to detect objects in their vicinity. The EE-SX671R is an optical Sensor that utilizes photointerrupters to detect objects, with particular emphasis on slot type mechanisms. This Sensor includes logic output, meaning that any object detected is interpreted as either ‘on’ or ‘off’. The EE-SX671R is particularly useful for precision automation or precise detection tasks such as part-sorting processes.

Application Field

The EE-SX671R has a number of possible applications, including use in the field of automation. The primary function for which the EE-SX671R is best suited is the detection of objects and the interruption of motion. For example, the EE-SX671R can be used in the manufacturing process to detect objects passing through a chute, with the infrared light detecting precise points along the passage. These can then be used to activate a motor to stop movement at the desired point.

The EE-SX671R is also commonly used in conveyor belt systems, where the Sensor can be used to detect the edge of a conveyor, and interrupt motion when necessary, such as when a belt transports items to the end of its target area. Furthermore, the EE-SX671R can detect objects and prevent collisions, such as when a robotic arm is picking items from one location and transporting them to a new area.

Working Principle

The EE-SX671R utilizes a slit or slot type of input to detect objects or interruption of optoelectronic beams. This Sensor includes an infrared light emitting diode (LED) and a phototransistor that are arranged across from one another. When a beam of infrared light is disturbed, the phototransistor captures the light and converts it into an electrical signal, which is then used to detect an object and alter the output.

The EE-SX671R operates by the infrared LED transmitting infrared light towards a receptacle. When an object is detected, the light is blocked. This interruption is then detected by the phototransistor, which then sends a signal to the logic output. This then determines whether the detected object is an ‘on’ or ‘off’ command, and the EE-SX671R will respond accordingly.

Conclusion

The EE-SX671R is an Optical Sensor with slot-type input. This Sensor can be used to detect objects with precision, and be employed in a number of automation processes as well as collision prevention. The EE-SX671R works by the infrared LED transmitting a beam of light which is detected by the phototransistor when an object is present. This then produces an input signal which is interpreted as either an ‘on’ or ‘off’ command by the logic output depending on the predetermined criteria.
