DIN Rail Terminal Block End Stops and Terminators

An end stop (terminator) is a fixing part fitted to both ends of a terminal block row on the rail to prevent the terminal blocks from sliding along the rail. In panel assembly it is used to hold terminal block groups in place, mark the start and end of a group and, in some types, carry the group label. This category includes small, large, screwless and group-label end stops suitable for the Onka MRK-OPK series in gray, beige, brown, red, blue, yellow, black and green. Choose the end stop by the terminal block series and rail type, the fixing method (screw-tightened or screwless), whether you need it to carry a group label, and the color that will distinguish the circuit group. An end stop is not a terminal block to which conductors are connected or a separator plate placed between groups; its only job is to mechanically fix the terminal block row on the rail.

How to choose End Stops and Terminators

An end stop (terminator) is a fixing part fitted to both ends of a terminal block row on the rail to prevent the terminal blocks from sliding along the rail. In panel assembly it is used to hold terminal block groups in place, mark the start and end of a group and, in some types, carry the group label.

  • Clarify whether the task is connection, cable routing, enclosure distribution or termination.
  • Match dimensions, thread standard, conductor cross-section and IP rating with the cable and panel.
  • Choose housing material and pack quantity according to the mounting environment.
