Connecting Registration
Sensors
The IMC-S/23x provides a high-speed optically isolated registration
input for each axis. These registration inputs require 2.5 mA at 5V DC
(each) to operate.
Each registration input may be individually configured to interface
directly with either 5V or 24V DC registration sensors as explained in
Configure the Registration Inputs earlier in this section. To prevent
damage to either the IMC-S/23x or the registration sensors, ensure that
these switches are set properly before connecting registration sensors.
If you are using current sourcing proximity switches, registration
sensors, or active-high encoder markers, connect them to the
IMC-S/23x using the same 4100-CCAxxF pre-engineered cable
assembly used for that axis’ discrete I/O, as shown below.
If you are using current sinking proximity switches, registration
sensors, or active-low encoder markers, connect them to the IMC-S/23x
using the same 4100-CCAxxF pre-engineered cable assembly used for
that axis’ discrete I/O, as shown below.

ATTENTION: Set the registration switches for 5V or
24V sensors before connecting registration devices.
