Motion sensors are widely used in various industries and play an important role in security and general monitoring. The EKMB1204112 is one such device commonly seen in the field, specializing in optical motion sensing.

Technical Specifications and Features

The EKMB1204112 is a dual beam leading edge optical motion sensor designed to detect objects that are moving in front of its sensing field. It has two 5V and one 10V ratings, and comes with a current output of 200mA and a sensitivity level of 0.5mV/A. The primary sensing element is comprised of two L-shaped photodiodes; when a target object enters the sensing field between the photodiodes, it will activate and cause a current to flow.

This device has a viewing angle of 120 degrees, and is capable of sensing objects up to 30 meters away. Additionally, it has a temperature range of -40°C to +80°C, and a response time of 250ms. This device is also designed to be resistant to both dust and water, with an IP67 rating.

Applications

The EKMB1204112 is particularly well suited for outdoor applications, as it is resistant to both dust and water. It can be used for security and surveillance, as it can detect moving objects from far away, as well as for object tracking and precise motion sensing. Because it is able to detect even subtle movements, it can be used in robotic systems, such as industrial robotic arms and robots with autonomous navigation.

It is also applicable for use in retail spaces, where it can be used to detect when customers pass through certain areas. Furthermore, it is commonly found in car washes, to detect when the vehicles have passed through specific areas. Additionally, it is also useful as a safety device, as it can detect sudden movement within the sensing field and alert the necessary personnel or systems.

Working Principle

The EKMB1204112 is an L-Shaped dual beam optical motion sensor, which works by detecting movement in its field of view. When something enters the sensing field, two beams of light are emitted from the photodiodes. As the object passes through the field, a decrease in the light emitted from the first beam and an increase in the light emitted from the second will be detected. This change in light is measured using a current output and compared to a sensitivity level set within the device. If the difference is greater than the sensitivity level, then the motion will be detected.

The device also has a built-in filtering mechanism to reduce false alarms due to external factors, such as temperature change. This filtering allows the device to only respond to signals which are significant enough to trigger the motion detection function.

Conclusion

The EKMB1204112 is an effective motion sensor designed specifically for outdoor use. Its dual beam leading edge optical sensing technology allows it to detect even slight movements, making it suitable for both security and monitoring purposes. Its long range of detection and high accuracy make it an ideal choice for many applications, such as security, surveillance, object tracking, robotic navigation, and safety.
