Why Choose This Machine

SD3-A1 Safety Laser Scanner Type3 PLd SIL2 provides flexible area safety protection for machine builders and system integrators. Instead of fixed physical safety fences, it creates virtual safety zones. It supports 8 zone switching and 190° wide scanning, ideal for dynamic production lines with frequent layout changes. The dust suppression and optical axis monitoring function greatly improve long-term reliability in factory environments.

Part of Your Smart Factory

Integrate Type3 Safety Laser Scanner SD3-A1 into your smart factory automation lines. Its programmable virtual safety zones fit robotic cells, machine tools and automated stations. Multi-scanner anti-interference design supports multiple safety sensors deployed in one workspace, protecting workers while keeping production flexible and efficient.

FAQ

Q: What benefit does 8-zone switching bring?

A: It allows the scanner to switch safety protection areas automatically for different production processes, eliminating repeated manual reconfiguration and saving setup time.

Q: What is the advantage of 190° wide scanning?

A: Wide 190° scanning covers large semi-circular monitoring space, one unit can cover a wide area and reduce the quantity of safety sensors required.

Q: Why is dust and insect suppression valuable?

A: It prevents false machine stops caused by flying insects or dust particles in factory workshops, improving uptime and reducing unnecessary production interruptions.
