Optical Data Transmission Module

Optical Link Characteristics

The ST100 Series Optical Data Transmission Sensor uses infrared lasers for data transmission, employing two laser wavelengths: 785nm and 850nm, for mutual data interaction. The original spot size of each laser is approximately 5mm, with a beam divergence angle of 1°, and the corresponding receiver field of view angle is 1.5°.

Optical Data Transmission Main Applications

The ST100 Series Optical Data Transmission Sensor utilizies optical transmission technology, eliminating the need for physical data transmission cables. As a result, it is particularly suitable for environments where the use of cables is impractical, such as in confined spaces or complex environments. Its main applications include: smart warehousing, overhead cranes, reciprocating transport systems, port automation, stacker cranes, rail cars, and more.

ST100 Series and DS Series Interference-Free Parallel Operation

As storage and retrieval systems increasingly rely on dynamic calculation of position data, pre-calculated position drives can be optimized for high speed or low power consumption, depending on throughput requirements.

The ST100 Series laser-based broadband data transmission module provides additional benefits by offering parallel real-time images from aisles for position data. This aids in fault analysis and correction, as well as system optimization. New ST100 Series Optical Data Transmission Module enables protocol-free, high-speed Ethernet communication with bandwidth up to 100 Mbit/s, making it ideal for internal logistics applications. The module also offers diagnostic capabilities via a display and digital outputs, providing a comprehensive solution for fast debugging and high operational availability.

This module is suitable for wireless data transmission to storage and retrieval devices in automatic high-bay warehouses or transfer vehicles. With a bandwidth of 100 Mbit/s, it can handle large amounts of data, such as diagnostic data generated by cameras installed on storage and retrieval devices for monitoring purposes. When combined with the DS Series Long Distance Laser Ranging Sensor, it offers enhanced functionality.

The ST100 Series Optical Data Transmission Module and DS Series Long Distance Optical Distance Sensors form a powerful suite for linear positioning, offering advanced and investment-secure positioning solutions for storage and retrieval systems from a single source. The 100 Mbit/s high Ethernet data transmission bandwidth enables the implementation of additional availability optimization options.

DS Series Long-Distance Laser Rangefinder

Long-Distance Laser Rangefinder Function of the DS Series

The DS Series Long Distance Laser Rangender consists of a laser emitter, an optical receiving device, and an internal processing circuit and software system. The sensor emits a laser beam, which is reflected by a reflector and received by the optical receiving device. The built-in evaluation and measurement unit uses the Time of Flight (TOF) method with phase correlation to accurately calculate the distance between the sensor and the reflector. During the measurement, the reflector or equipment can move linearly along the laser beam path, and the sensor continuously tracks and calculates the distance. The measurement results are transmitted through a data interface.
