Optical sensors are key components of various devices used in various industries, such as industrial automation, motorized machines, motion control, and lighting control. The E3ZM-T81 2M from Omron Automation is a photoelectric hazard-prevention type safety-door switch suitable for a variety of applications. It measures a maximum distance of 2m and provides reliable detection with an improved waveform function that smoothens out the input waveform. In this article, we will discuss the application field and working principle of the E3ZM-T81 2M.

The E3ZM-T81 2M is a static-type optical sensor suitable for a wide range of applications such as measuring the presence or absence of parts, detecting product concentration, controlling product weight, and for positioning. The sensing range of 2m is ideal for detecting the presence of objects at longer distances. The improved waveform function smoothens out the waveforms of AC input, so that there are minimal lag times and ripple effects, providing users with a reliable detection performance.

The working principle of the E3ZM-T81 2M is based on the optical-principle of triangulation. In this optic-principle triangulation, the optical sensor projects an infrared beam onto the formed object and evaluates the response of the light reflected from the object. The object\'s presence is determined by the distance obtained through the evaluation of the light beam. The E3ZM-T81 2M also comes with a built-in light source, making it easy to use without being connected to an external light source.

The E3ZM-T81 2M has a small size and is designed to be dust-resistant and moisture-resistant. The sensing head has a rib-shaped design which ensures the resistance against ingress of dust particles as well as the shorter response time compared to single-element type. The special shape of the sensing head also makes it easy to mount the sensor close to the object to be detected.

The sensing range of the E3ZM-T81 2M can be adjusted to the user’s specifications depending on the application, by a step width of 0.2m to a maximum of 2m. The sensing range is adjusted using the Teach-in knobs, meaning no programming is necessary. This makes the sensor suitable for applications that are not only reliable but also require minimum setup time.

The E3ZM-T81 2M features a pilot LED that lights up whenever it is operating. This helps to quickly and easily check the status of the sensor. The light source also features a bright red LED that can be seen clearly from a distance of several meters and makes it easy to detect the zone of presence.

The E3ZM-T81 2M from Omron Automation is a reliable and versatile optical sensor that can be used for a variety of applications. The sensing range of 2m and improved waveform feature make it ideal for long-distance applications where reliable detection is required. The Teach-in knobs also make it extremely easy to adjust the sensing range to the user’s specifications, without having to do any programming. The built-in light source and visible red LED also provide users with quick and easy status checking, making it a great choice of sensor for various industrial applications.
