Detection Distance 2 M Cable Laser Class 2 Keyence LR-TB2000
*2 The laser classification for FDA (CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice No.50.
*3 You can select the I/O from the following combinations.
Control output × 2, control output + external input
Control output + analog output (LR-TB5000/TB5000C/TB5000CL only)
External input + analog output (LR-TB5000/TB5000C/TB5000CL only)
(For details on the setting method, see the instruction manual.)
*4 IO-Link specification v.1.1/COM2 (38.4 kbps) is supported. You can download a setup file from the KEYENCE website (http://www.keyence.com).
If you are using the product in an environment in which you cannot download files over the Internet, contact your nearest KEYENCE office.
