In the automation process of logistics and warehousing, stacker cranes, as the core equipment of three-dimensional warehouses, have the characteristics of high precision and high speed, and can quickly and accurately complete the tasks of goods storage, retrieval, and handling.

However, in practical applications, the photoelectric sensors on stacker cranes need to face various complex detection environments, such as large cargo, long detection distances (within 10 meters), and background reflection interference.

To meet these needs

Meiji TOF photoelectric sensor ELT series is born to meet the demand

The Akusense TOF photoelectric sensor uses the time-of-flight (TOF) principle to determine object distance by emitting pulsed laser and measuring reflection time. This type of sensor has high precision, long-distance detection capability, and is not affected by the size or material of the measured workpiece. In addition, the Meiji TOF photoelectric sensor also has background suppression function, which can effectively reduce or eliminate the interference of reflected light from non target objects, ensuring accurate detection of target objects.

⭐  Remote detection:

The Meiji TOF photoelectric sensor has a sensing distance of 3/5/10 meters, which can meet the requirements of large cargo and long detection distance.

By adopting advanced laser ranging technology, sensors can accurately measure the distance between goods and sensors, ensuring the accuracy of detection.

⭐ Background suppression:

To address the issue of shelf reflection interference, Meiji TOF photoelectric sensors use intelligent algorithms and multi frequency modulation technology to accurately identify and suppress background interference, ensuring measurement accuracy and stability.

⭐ NPC+PNP Free Switching:

The Meiji TOF photoelectric sensor supports two output modes, NPN and PNP, and can be switched through simple settings.

This enables sensors to seamlessly connect with different types of control systems and devices such as PLCs, improving the flexibility and compatibility of the system.

By using Meiji TOF photoelectric sensors, the stacker crane can achieve precise detection of the position of goods. When the sensor detects goods on the shelf, it will send a signal to remind the shuttle to carry them; When no goods are detected on the shelf, a signal will be sent to drive the shuttle to place the goods in the designated location. This not only improves warehousing efficiency, but also reduces the risk of misjudgment and missed judgment
