Product Description

The TL-SM511LSA-20KM module, a key component of the SM511 series laser sensor family, is a high-performance 20km fiber transceiver tailored for industrial automation and telecommunications. It supports dual-channel digital I/O and interfaces seamlessly with up to four expansion modules via standard fiber-optic connectors. Operating within 9-36V DC and -40°C to +75°C, it ensures stable performance in harsh environments. The module integrates industrial-grade communication protocols (RS-485/Modbus) and achieves precise laser-based detection up to 20 meters, complemented by its 20km optical transmission range. Designed for applications in logistics, remote monitoring, and robotics, its rugged housing and low-latency data transmission stand out, though installation complexity and lack of built-in power backup may require auxiliary systems. Compact and screen-free, it prioritizes reliability in space-sensitive setups.
