Photoelectric, industrial optical sensors are crucial components, when it comes to automation, and they have applications in various industries. The E3Z-R81K 2M is a reliable, public-customized photoelectric sensor provided by Omron Corporation which is popularly used in the industrial sector. The main aims of this article are to describe the primary application field and working principle of the E3Z-R81K 2M.

The E3Z-R81K 2M is a type of simple shape, presence control photoelectric sensor. It is suitable for detecting the presence of objects, like detecting the position of a part or confirming the absence of a part. Besides, it can be used for counting as it is robust enough to tolerate rough handling and resists vibration or shock. As a result, the E3Z-R81K 2M is adopted in conveying systems, automotive production lines, closing processes or packaging machines.

The working principle underlying the E3Z-R81K 2M is the emission of a visible red light beam from the transmitter unit. The transmitted light is received by the receiver unit, thereby completing the path of light. If a single object interferes with the light path, then the current path of light becomes incomplete. This results in interruption of the current flow, and the supply circuit inside the sensor gets cut off causing an output signal to be generated either in the form of a switch or a transistor.

Moreover, the E3Z-R81K 2M is designed with two transmission formats, namely, fractional polarity response and transmission by mirror reflection. In fractional polarity response, the received light can alter the polarity while transmission by mirror reflection uses the mirror to focus the transmitted light for greater accuracy. Both approaches, employ a two-wire configuration and the photoelectric switch has an LED indicator that indicates the output status.

The E3Z-R81K 2M is a versatile photomicrosensor which combines a number of different safety features. Thus, it is becoming more and more popular in the industrial sector to meet specific application requirements. It also includes alarms in case of faults, as well as afterglow elimination for cleaning, resetting, and other types of adjustments. Furthermore, its protection rating of IP67 ensures that dust and dirt won\'t affect the photoelectric switch even when it is constantly exposed to the environment.

In conclusion, the E3Z-R81K 2M is a reliable, public-customized photoelectric sensor that offers a two-wire configuration, as well as a fractional polarity response or transmission by mirror reflection. Moreover, it can be used for detecting the presence of objects, as well as for counting. It is also designed with several safety features to protect it against different environmental conditions, as well as to alarm its user of any potential faults. Hence, this optical sensor is suitable for use in various industrial production systems.
