OS32C-4M-DM Safety Laser Scanner


The STI OS32C-DM Safety Laser Scanner reports status and measurement data via EtherNet/IP. This helps keep machines up and running by enabling users to check the operating state analyze the cause of an emergency stop via LAN, and take quick corrective action, even in large-scale applications with multiple scanners.


These simple and versatile STI safety laser scanners are available with new user tools that help speed customer development time and conserve engineering resources. Easy-to-use function blocks are ideal for simple PLC-controlled status and data updates. A simple and effective method of integrating the status and measurement data to a PLC, these function blocks can be used in the PLC code to automatically configure the PLC to process and display the information. Software examples are available for large process PC-controlled applications where large amounts of data are logged to determine product quality, consistency or process variations. The updated configuration tool now provides a “maintenance access level” that enables the user to make only non-safety-related programming changes and employs a “non-safety checksum” for easier re-commissioning when non-safety changes are made. A “zone coordinate import/export” function allows users to modify the shape and size of a monitoring zone by importing coordinates from a text file.


All STI OS32C safety laser scanners provide configurable object resolutions of 30, 40, 50, and 70 mm to accommodate hand and arm detection applications. They feature a compact 104.5 mm profile, light 1.3 kg weight, and consume just 5 W power (3.75 W in standby mode). Combined with innovative features that include up to 70 sets of highly flexible and easily configurable detection zones, the OS32C is easy to handle and install and delivers the versatility needed to solve diverse presence detection and collision avoidance application needs. The status display and eight patented Individual Sector Indicators also enable users to determine at a glance the unit’s operating state and error codes and assess the direction of an intrusion.
