Clamp Terminal
Blocks
Screw-less clamp terminal blocks use clamps to attach wires, and do not
require screws. In addition to control signal wiring to Servo Drivers, clamp ter-
minal blocks can be used to connect sensors and external devices. A ferrule,
however, must be connected to the sensor or external device cable when con-
necting to clamp terminal blocks.
The following table shows the suitable ferrules.
Wiring Method • Inserting Wires
Insert the ferrule into the terminal hole.
• Removing Wires
Push and hold the release button on top of the terminal hole with a small
flat-blade screwdriver and remove the wire.
The following screwdriver can be used when removing wires.
