Length of the mounting rails
Table 4-1 Mounting rails - Overview
Mounting rail length Usable length for modules Order number
160 mm 120 mm 6ES7 390-1AB60-0AA0
482.6 mm 450 mm 6ES7 390-1AE80-0AA0
530 mm 480 mm 6ES7 390-1AF30-0AA0
830 mm 780 mm 6ES7 390-1AJ30-0AA0
2000 mm cut to length as required 6ES7 390-1BC00-0AA0
In contrast to other rails, the 2 m mounting rail is not equipped with any fixing holes. These
must be drilled, allowing optimal adaptation of the 2 m rail to your application.
