Key Features

The LE200 measures linear movements without physical contact. The phase shift measurement principle ensures wear-free operation. Therefore, maintenance costs remain very low over time.

The 0.1 mm physical resolution provides precise distance measurement. Similarly, the 1000 values per second refresh rate captures fast movements. Consequently, this device suits high-speed positioning applications.

Three measuring ranges cover various application needs. For example, the standard range reaches 125 meters. Likewise, range extension 1 reaches 170 meters. Finally, range extension 2 reaches 195 meters.

The rugged IP65 construction survives harsh industrial environments. As a result, the device withstands 50 m/s² vibration and 300 m/s² shock. Furthermore, the optional integrated heating enables operation down to -30°C.

Flexible programming allows customer specific solutions. For instance, the TRWinProg software enables easy parameter adjustment. Meanwhile, the EtherNet/IP interface integrates seamlessly with Rockwell Automation systems. Finally, the device profile 0x22 supports standard encoder communication.

Installation Guidelines

Install the LE200 in a location with a clear line of sight to the reflector. Mount the device securely on a vibration-isolated surface. In addition, ensure the operating temperature stays within specified limits.

Connect 18-27 VDC power to the supply terminals. Use the optional 24 VDC heating supply for cold environments. Similarly, connect the EtherNet/IP interface to your industrial network. Use shielded CAT5e or CAT6 cables for best performance.

Configure the IP address using the programming tool. Then set the measuring range and resolution parameters. After that, program the external input and output functions as needed. Finally, aim the laser at the reflector foil for optimal measurement.

Do not stare directly into the laser beam. Therefore, always observe all laser safety regulations. The device complies with FDA 21CFR 1040.10 with Laser Notice No. 50.
